AROUND THE WORLD IN NINE DAYS

It was 14 December 1986. The afternoon sun was weak. It could not kill the chill in the air over the Mojave Desert of California where the Edwards Air Force Base is located. However the cold did not dampen the enthusiasm of the men who scurried around the tarmac, in a state of excite­ment. The centre of their attention was ‘a weird and won­derful aircraft called The Voyager which looked like a de­formed letter of the alphabet and carried its fuel in wings which could flex 30 ft (9 m) either way’.

It was a strange looking aircraft, no doubt. Yet it seemed just right for the grand trip round the world, nonstop, that Dick Rutan and his girlfriend Jeana Yeager had planned.

The idea for this daring trip was born about six years back while Dick, Jeana and Dick’s brother Burt sat at a bar, one evening.

Dick had been a fighter pilot. He had seen action in Vietnam, carried out several bombing sorties before his plane was downed. Luckily he was dumped into the South China Sea and picked up by a US rescue boat. After he retired from the Air Force, he joined his brother Burt, who was improv­ing and experimenting with new designs for aircraft. Dick tested the new machines. Often he performed stunts at air shows. At one such show he met Jeana. She was an ace sky – diver and was preparing to fly helicopters. They became friends and then lovers.

Dick and Burt remembered their days in Oregon and

California, of their childhood obsession with flying, of the happy times they had designing and flying toy planes. The talks veered round to the challenges that aviation of­fered. Dick referred to a record set by US pilots in 1962. They had flown, non-stop, a distance of about 12,500 miles (20,000 km).

"That record can be broken," Burt lowered his voice.

Both Dick and Jeana looked up. Then came a funny idea. How about circling the earth non-stop in an aircraft? Burt calculated the distance that the aircraft would have to cover. It came to anything between 40,000 to 42,000 km. That was double the distance (slightly over 20,000 km) recorded by Air Force pilots in 1962. Yet Burt felt it could be done. He said he would design a special aircraft. It would have to be light, yet strong and sturdy. It would carry enough fuel to power the flight around the earth. That would make the aircraft a virtual ‘flying fuel tank’.

Dick looked at Burt, winked at Jeana and grinned, "Jeana and I shall fly the aircraft, try to girdle the earth non­stop". Dick later recollected, "I knew from that instant that we were going to do the thing or die trying".

Burt had built several sail planes and sports aircraft. He took just a few minutes to mentally conceive a design of the aircraft that could possibly make the round trip possi­ble. He pulled out a paper napkin and drew the design on it. Dick and Jeana examined it. They felt a little uneasy about the weird design, but they kept their fears to themselves. Burt detailed his plans. Over the weeks, the design started gaining clarity. Burt spoke of using graphite fibre and alu­minium frames to make the aircraft very light. He estimated its weight at about 900 kg.

Room for fuel gained top priority. The aircraft would need to take along 3,100 kg of aviation fuel. Burt said he would fix 17 fuel tanks. They would be placed wherever space could be found—under the wings, in the fuselage, even in the outrigger booms that firmed up the wings. That set severe pressure on space. The squeeze on space led to a cockpit, hardly 7.5 feet by 3.5 feet (2.3 m x 1.1. m). Here, Burt grinned, Dick and Jeana would have to work, eat, sleep and relax, spend around 10 days. Irene Rutan, mother of the two boys, took one look at the cabin and snapped, "You didn’t design that with people in mind". Burt softly purred, "No, Ma, I didn’t. I designed it to go round the world".

To reduce weight, Burt cut down on the oxygen needed to keep the fliers in comfort while flying at altitudes rang­ing from 8,000 to 12,000 ft (2,400 m to 3,600 m) to the mini­mum; scrapped insulation needed to make the aircraft soundproof, cut down on heavy fuel gauges. Burt, however, offered to power the aircraft with twin engines. That was the only concession he offered.

Dick and Jeana winced at the hardships that they would have to face. It was not going to be easy, they agreed. Records could not be broken nor created the easy way.

Burt estimated the cost of the aircraft at $2 million. That was a fabulous sum. Where would the funds come from? Burt had gained a reputation in the field of aviation. That stood him in good stead when he passed the hat around for financial and material help. Every donation was hailed as assistance coming from a VIP (Voyage Important People). Many corporate bodies donated instruments, tools and gadg­ets to equip the aircraft.

It took the team six years to produce the weird aircraft. It was named The Voyager. It cost the team less than $2 mil­lion. Burt joked, while showing his creation to the member of the press, "It would have been $400 million if a Pentagon contractor had built on a cost-plus and over-time basis".

In July 1986, Dick and Jeana carried out a test flight, flew a distance of 18,600 km, non-stop. It took them four and a half days and just half the fuel on board to complete the flight. This success emboldened them.

They waited for setting out on the historic flight round the earth. Burt carried out rigorous check of every part of the aircraft. Finally he declared it airworthy.

The date for the final takeoff was announced.

On 14 December 1986, Dick and Jeana shook hands with friends and officials on the tarmac and climbed into the cockpit. Dick sat behind the controls, started the engines, waited till they gained enough thrust and then let the air­craft cruise along the runway. The aircraft picked up speed, but the wings, heavy with fuel, dipped and dragged. Burt who was following The Voyager, in a spotter plane, got a shock. The Voyager was not gaining the requisite lift even after covering most of the runway A crash seemed inevita­ble. He warned Dick over wireless to abort the flight. But the message did not go through. Burt watched, his heart in his mouth, when the miracle happened. The aircraft rose in the air with just about 200 metre of runway to spare. Burt’s hopes rose, only to sink almost instantly when he noticed that the tips of the wings had been damaged. He advised Dick to sever the tips off. That was a risky operation. But Dick managed to reach out of the cockpit, donning a para­chute, and clip the damaged tips off.

The first day’s flight was smooth and uneventful. The wings, even though chipped, did not pose a problem. On the second day, while over the sea near the Philippines, the aircraft faced a cyclone. Dick swerved, kept out of the eye of the cyclone with wind speed of 75 miles (120 km), taking a longer route, often gaining extra speed from the tailwinds. Then came a new danger. The aircraft had to be steered through a narrow corridor that lay between hostile Vietnam­ese airspace and dangerous weather pockets. The pilots managed to get through, safely. On the fourth day, the air­craft flew over Kandy in Sri Lanka. The pilots enjoyed the grand sight of sunset from their lofty flying perch. They flew over Africa on the fifth day. Weather forecasts indicated air turbulence at lower levels. So Dick and Jeana flew at 20,000 ft (6,000 m), using both engines to gain the required lift.

The deafening noise produced by the aircraft was wrecking their mental balance. The constricted space trou­bled them. Time seemed to stretch into infinity. Every hour they spent on the aircraft seemed to be as long as a day. They wished they had room enough to stretch their legs. They craved for a good long undisturbed sleep. But these luxuries lay beyond their reach. That often left one or the other of them sulking, at times, and often, in bad mood. There were times when they cursed themselves for being so foolhardy. Once, even Dick, who usually never grumbled, let the guard down and told his brother, Burt, who was moni­toring the flight from the ground: "I’m tired. I want to go to bed in California. Vector me home". But Jeana cheered him, told him that they were almost home, more than halfway through! When fair weather held, the two joked, sang to­gether old ditties, felt confident of completing the mission. But often the weather turned foul; or the aircraft developed trouble. They however clung on, determined to do or die.

They received a fright during the last lap of the jour­ney. The gauges indicated that the rear engine was getting overheated. What had caused the trouble? It didn’t take them long to realise that they had not replenished its oil supply in time. They took quick remedial steps. The engine began to behave normally.

Every passing day made life more miserable. How the two wished their ordeal would end! Yet this was an ordeal they had chosen to face willingly. They could not drop out, midway. They had covered more than four-fifths of the gir­dle. "This too would pass", they drew courage.

While flying over Brazil, the aircraft ran into a turbu­lence, heeled over, one wing pointing at the sky above, one at the sea below. Dick and Jeana were tossed around for a considerable period. They worked at the controls, managed to lift the aircraft beyond the turbulence. Bad weather over the Caribbean forced them to reroute the flight over Panama and the West Coast of Mexico.

Finally, on the ninth day after take off, The Voyager zoomed over the sky, touched down at the Air Force Air­port at Mojave Desert. The tyres screeched when the brakes bit into them and forced them to stop whirling. Then the aircraft came to a dead stop.

Dick quickly grabbed a cowboy hat, set it at an angle on his head and emerged from the cramped cockpit, flash­ing the victory sign. Right behind him appeared Jeana, beam­ing a smile that reflected the abiding joy within. Instantly the two were sucked into a cheering crowd of admirers and friends, and reporters. Thousands of flash bulbs blew their tops off recording the tumultuous scenes at the airport.

It marked their finest hour. They had flown an aircraft, girdled the earth non-stop and thus created a record. This record would remain forever. Dick struck the right note, af­ter the historic flight, "Life is an opportunity. It’s only lim­ited by what you can dream about".

Ronald Reagan conferred on Dick, Jeana and Burt the Presidential Citizen’s medal and noted, "When we saw you coming home—so ungainly yet so graceful—well, that’s about the best present America could have had". Dick re­plied, with a merry chuckle, "This is done by individual citizens of this great country who had the freedom to pur­sue a great dream".

The three had truly made a great dream come true.

INDIANS GET AIRBORNE

Indians were late entrants to the field. But we have made up for lost time, to a large extent. Of course, we are still much behind the developed nations. Finance stands in the way, not lack of spirit or enthusiasm or commitment. Yet many Indians have overcome the limitations, created avia­tion history. It is impossible to refer to all of them. However the feats of three Indians, detailed in this section, make us swell with pride.

The first Indian to dare to fly was Jahangir Rattanji Tata. He was drawn to it when he was hardly ten. He stood at the beach, on the French Coast, close to where he lived with his parents and let his eyes rivet on a small plane in flight. The drone of the aircraft became louder as it came near, started to descend and touched down on the sand. The pi­lot hopped out of the cockpit.

"Uncle", Jahangir screamed when he identified the pilot, Bleriot, a neighbour and a family friend. He was the first man to fly across the English Channel. Jahangir held him by the hand and looked at him with admiration. "How I wish I too could fly!" the boy turned hopefully to the elder.

"Meet me here tomorrow at 10. I shall take you on a joy ride", said Bleriot.

Next day the boy had his first flight. "Some day, Uncle, I shall fly my own plane", said the boy.

"Why not!" Bleirot gave the boy an encouraging nod.

"Can I fly planes?" the boy asked his parents, later in the day.

"Of course! Flying can be a hobby," his father, Ratanji Dadabhai Tata, held him in a warm hug.

In 1929, Jahangir received the pilot’s licence. In 1930, he made a bid for the Aga Khan Trophy, offered to the first Indian who flew solo from India to Britain or from Britain to India, in the shortest time. Jahangir (better known as JRD), entered the race, took off in a Puss Moth aircraft and flew West, heading for Britain. Around the same time, another young man, Aspi Engineer, set out from Britain and headed for India.

JRD ran short of fuel, while flying over Egypt, and force-landed in the desert. He trekked to an outpost at Rutbah Wells, once an important stop on the Imperial Air­ways’ route, gathered fuel and returned to resume the flight. At the next stop, on the desert route, he met Aspi Engineer. JRD greeted him warmly. Aspi grinned, but his eyes wore a beaten look.

"What is troubling you, Aspi?" JRD asked.

"I need spares, but where will I get spares in this desert? I think I have to drop out of the race", Aspi scowled.

"Cheer up, Aspi. I have some spares with me. Come, take what you want", JRD gently picked up Aspi’s hand.

Aspi jumped with joy, thanked JRD, picked the spares he needed, carried out the repairs and tested the engine. "Good luck", said JRD.

Soon both resumed their flights. JRD headed West; and Aspi flew East. Both completed the trip. But Aspi recorded better timing and won the race.

"I owe my success to JRD", he said. "But for those spares, I would never have made it".

Aspi was at the airport when JRD landed at Karachi. JRD stepped out of the cockpit and ran into the warm hug of Aspi. His eyes opened wide when Aspi asked him to
accept a guard of honour, presented by a group of boy scouts. Aspi had specially brought them to the airport to make the welcome memorable. That was perhaps the best homecom­ing that JRD ever had!

Many years later, JRD noted, "I am glad that Aspi won because it helped him into the Air Force". Aspi rose to high ranks, retired as the Chief of the Indian Air Force.

Подпись: Fig. 11.1: JRD Tata JRD joined the family’s busi­ness house (Fig. 11.1). In between, he took time to fly planes. Around that time, the Imperial Airways planned a flight between London and Calcutta via Karachi. A friend,

Neville Vintcent, a dare devil flier from Britain, saw a golden chance.

He suggested to JRD, "Why don’t you start an airline service linking Bombay with Karachi?" JRD dis­cussed it with Uncle Dorab. "No",

roared the old man. But JRD kept up pressure. Finally he received the green signal. Tata Aviation service was formed.

The service started with a solo flight by JRD on 15 Oc­tober 1932. He took off from Karachi, in a single-engine Puss Moth, flew solo, bringing mail to Bombay. It was a historic flight. The Airlines grew in strength. In 1948, it became Air India International. After nationalisation, the government appointed JRD as the Chairman.

In 1982, he celebrated the fiftieth anniversary of his first flight, flying the same route in a De Havilland Leopard Moth. That was indeed a record.

Vijaypath Singhania, a 49-year-old industrialist of Kanpur, chose another track to create a record. He too loved flying, knew how aviation had grown through the years since the

flight by the Wright brothers in 1903.

One day, while going over the records in aviation, he felt depressed. ‘India does not have any aviation records’, he moaned. How he wished someone would accept the chal­lenge and create aviation history? Then it struck him. Why shouldn’t he himself accept the challenge?

Easier said than done. But Vijaypath was equal to the task. He resolved to carry out the plan. His search for possi­ble records to create or break led him to the feat of Brian Milton, a journalist. Milton had flown a microlite aircraft, solo, from Britain to India, in 34 days. Could he fly the dis­tance in lesser number of days and thus create a new record? That seemed a target he could achieve.

He looked out for a microlite aircraft that would serve him well. Finally, after going round Aircraft factories all around the globe, he chose an aircraft manufactured by a British firm. It weighed just under 150 kg (6.4 m long; wing­span 10 m and maximum sped of 60 knots). He named it L’esprit d’lndian Post.

Preparations began in right earnest. The aircraft was readied for the 9600 km flight to Delhi. The maximum dis­tance that the single engine aircraft could fly, non-stop, was 960 kmph. The route and the scheduled halts enroute were meticulously chalked out. Medical facilities were lined up at the halts to provide for emergencies. Landing permits at various proposed stops were obtained. Due note was also taken of the dangers posed by the turbulence over the Medi­terranean Sea and over the Gulf of Oman.

On 15 August 1988, Vijaypath took off from Biggin Hill, outside London. Clouds blinded him while he flew over the Alps. He had to descend below the clouds, fly rather very low, hardly 100 m, along the coast of Italy, to avoid the mist. The fuel tank cracked and gave some anxious moments. But he safely landed at the next stop and set it right. While crossing the Mediterranean, he had his life jacket on and
carried a shark repellant. "Every time I would spot a ship, I would start calculating how long it would take the vessels to reach me if I fell", he joked.

The aircraft ran into a crosswind and was tossed around, giving him many anxious moments. Overflying the Saudi desert, the plane got caught in sandstorms. It required all his skill to steer the plane through. When he landed, the wind was so strong that the aircraft came to a dead stop in just under 4 m. Occasionally technical snags delayed his plan. At one stage, he was behind the time set by Milton by about two days. But he made up for lost time, thanks to some fine weather. He landed at Ahmedabad, 21 days after taking off from London, to a rousing reception. He had beaten Milton’s record by 11 days.

The nation hailed his feat. JRD was at the tarmac of Safdarjang Airport, on 11 September, to welcome him. Milton too was present. He complimented Vijaypath on breaking his record. Vijaypath had raised India’s image.

Harji Malik was one of the first Indians to be commissioned in the Royal Air Force. After independence, the Indian Air Force came into being. It played a major role in defending the nation. The officers and men displayed exceptional gal­lantry on the battlefield. Among them the name of Flying Officer Nirmaljeet Singh Sekhon stands out (Fig. 11.2).

image42It was 14 December 1971. India was at war with Pakistan. A Gnat detachment was moved to Srinagar. A 25-year-old ace pilot, Sekhon, who had flown the Gnat on several missions, was standing at the window of the duty room at Srinagar. He drew the collar closer as the chill wind wafted in. Then he heard the deafening scream of the siren. He noticed four Fig u 2. sekhon

Pakistani Sabres zooming toward the airport. Behind these planes came two more. The enemy aircraft bombed the air­port. Four of the ten aircraft held at the airport were dam­aged.

"I will get you, for sure", Sekhon swore, while he sped to the hangar. He neared one of the gnats that had not been damaged. He found Srawan Singh, an airman, bleeding, badly hurt, yet boldly checking the aircraft, and asked him, "Is this aircraft fit to fly?" The man nodded his head.

Sekhon got into the cockpit. "Take my advice. Don’t go after them. There are six of them. You can’t hunt them down", the man warned, before collapsing.

Sekhon started the engine. He got clearance to take off and was soon in flight. He went after the Sabres. He spot­ted two of them, flying low, almost scraping the tops of trees. He took them by surprise. His guns boomed before the en­emy knew what was happening. The two Sabres were hit. They spun like leaves, caught in a storm, and crashed.

Sekhon steadied the Gnat at a height of 200 m and looked out for the remaining four Sabres. He knew that he no longer enjoyed the advantage of taking them unawares. He saw in the rear mirror three Sabres coming after him. He quickly set the Gnat on a back roll. The enemy pilots didn’t anticipate that move. They banked to the right. Sekhon got just enough time to shoot one of them down. The other two regrouped and charged. This time Sekhon could not avoid a direct hit. The tail of the aircraft burst into flames. The engine went dead. The left wing caught fire and fell off. Sekhon took a deep breath as the plane started to plunge. Then his eyes lit with joy. He noticed the tracers fired by ack-ack guns on the ground, tearing the bellies of the Sa­bres. He was still savouring this sight when his plane hit the ground. Sekhon died with a smile on his lips.

The nation honoured him with the Param Vir Chakra.

HELICOPTERS

Aircraft needs to pick up immense speed, on the ground, before it can get airborne. The speed at which air runs over and under the wings (Bernoulli’s principle), provides the upward thrust. Higher speeds generate more powerful thrusts and thence more lift.

Aircraft have giant wheels. The runways at modern airports are very long. The pilot starts the engine, revs it up and waits for the engine to gain enough power and thrust before he pulls the lever. The aircraft gains speed. More speed and still more speed! Then, suddenly, the nose of the aircraft tilts up. It cuts its way through space. The nose moves further up. The aircraft gets bodily lifted. The steep climb ends, once the aircraft gains the height it needs to cruise. The pilot presses a control button. The wheels retract and slip snugly into the body of the aircraft.

Runways are essential to put an aircraft in flight and permit it to land back. The aircraft is of no use where this facility does not exist. At such places, the helicopter comes into play (Fig. 12.1). The helicopter has a main rotor and a tail rotor. They are mounted on top of the frame. The main rotor provides the lift. The tail rotor checks the tendency of the helicopter to pull in a direction opposite to that set by the main rotor. The rotors rotate at very high speed, force the air to part and provide the necessary lift.

The helicopter can move in any direction or simply hover over one place by suitable adjustment of the angles

of the blades of the main rotor and the tail rotor. The adjust­ments are made with the help of pedals and levers.

image44

The basic idea for the helicopter goes back to 12th cen­tury China. A toy-maker shaped a slim elegant shaft with holes from wood. Into the holes, he inserted and fixed small arms, shaped with care. The toy looked like a huge screw. The man added three propeller-like wings attached to one end. A firm tug at the free end of a string that wound round the central rod sent the toy into a spin. This spin produced the lift and made the toy fly.

Leonardo da Vinci, one of the greatest artists of all times, was a genius (Fig. 12.2). His interests were varied. He loved to paint. Da Vinci spent hours, observing birds in flight. He drew pictures of birds in flight, studied the anatomy of birds to find out the secret of flight. This quest led him to the details about the old Chinese toy.

He worked on the design and
drew the blueprint for a machine that resembled a giant screw. He called it, ‘Helipteron’, by combining two Greek words, Heli (means spiral) and Pteron (wings). Da Vinci be­lieved that it could fly. But how could it draw power to stay airborne? He thought four men could work the bars, at­tached to the airscrew. He left it at that.

Centuries later, Lomonosov, a Russian scientist, put a crude form of the helipteron in flight in 1754. In 1843, Sir George Cayley spent time to fabricate a flying machine that would take off vertically.

Louis and Jaques Breguet were siblings. They flew kites, spun out boomerangs that returned to them after short flights. Then they read about the helipteron. They assem­bled crude replicas with whatever they could lay their hands on. This childhood interest led them into the field of flight, once they were on their own. Charles Richet, another young man, joined them. The three spent all their spare time on the design of the helicopter. They called it the Gyroplane. The rotors whirled very fast. In 1907, the machine rose by 0.6 m on the first attempt. On the second try, it lifted itself bodily to a height of 1.6 m.

In the same year, Paul Cornu came up with a more effective design. It had twin rotor blades, powered by a gaso­line engine. The helicopter lifted itself and Paul up in space. It rose to a height of 0.6 m and stayed aloft for about 20 seconds. In the next trial, the helicopter rose up, taking Paul and his brother too aloft.

These were small beginnings, faltering steps taken by the pioneers. It took three more decades before the helicop­ter truly entered the field of aviation. Heinrich Focke, a Ger­man technologist, studied the work done by the pioneers. He improved on the designs. He carried out tests with his machines. Finally he felt confident that he had a design of a helicopter that would fly as freely as an aircraft.

In 1938, Heinrich announced that he would hold a public demonstration in Berlin. Huge crowds gathered to watch the air show. The helicopter stood at the centre of a wide open ground. Hanna Reitsch, a daring young dame, was at the controls. Heinrich went round, making last minute checks. Finally, sure that everything was in perfect working order, he signalled to Hanna. She started the en­gine. The deafening sound of the rotors, whirling madly, resounded in the air. People craned their necks to get a bet­ter glimpse of the grand show. The helicopter rose in space. It was incredible. The machine kept gaining height. On and on to record a height of 2,400 m! It flew forward at 120 kmph; and backward at the speed of 32 kmph. It covered a dis­tance of about 225 km. The helicopter came of age, on that historic day.

From then on, its growth was phenomenal. It devel­oped more range and speed, and found its place in civil and military operations.

Helicopters airlift wounded soldiers from forward lines to base hospitals; fly in to drop men and material in diffi­cult terrain, that are not accessible by road; maintain the supply line to forward posts. Helicopters are found active in war zones and disaster stricken areas. They carry out survey operations and weather studies. On ceremonial occasions, like the Republic Day, they fly low along or around the venue, drop flowers that make the scene truly colourful.

Helicopters were held in readiness, on 24 July 1969, to pick up the astronauts when Apollo 11 Command Module touched down on the high seas. The helicopter hovered above the space capsule. It dropped a flotation ring to the capsule and pulled up the’ astronauts.

In India, helicopters fly supply missions to several for­ward posts in the Himalayas. These missions are danger­ous. Pilots steer the helicopters between mountain ranges. Often wild winds rock the helicopters. It demands immense courage to carry out such missions, especially when the posts lie close to the enemy lines and danger of sniper fire always exists.

Naval helicopters undertake several specialised tasks. They carry out reconnaissance flights. Anti-submarine heli­copters use sonar devices. They spot enemy submarine and drop depth charges to explode near the submarine. If the hit connects, the submarine’s hull gets cracked or it is forced to surface. These sonar devices send out wave pulses into the waters and wait for the reflected echoes. They show up as a blip on a TV screen. Experts study the image and de­cide if it is a whale or a submarine. This decides the course of action to be taken. Naval helicopters rescue fishermen who drift at sea during cyclones.

Daring are those who man the helicopters. One instance comes to mind.

It was 13 October 1992. Tourists were in high spirits when they boarded the cable car to take them to the Timber Trail resort on the hilltop, close to the Shimla-Kalka high­way. The cable car slid across, providing a grand view of the gorge, about 2,500 m below. One moment the car was gliding, smoothly. Next moment, two of the wires of the cable car snapped. The car tilted, dangerously. Those in the car clutched the bars or held on to each other, while the car swung like a leaf in a storm. Fear gripped them. Would the remaining six wires hold on? Or would they snap and dump the car, with the tourists, into the gorge?

The local police immediately sought help from the IAF and the Army. The IAF station at Sarsawa received the call about two hours after sunset. It was too late to launch res­cue operation. The trapped tourists spent the night, on board the dangerously hanging car, hoping against hope that they would survive the ordeal.

Next morning, Air Force helicopters flew in. They stud­ied the terrain and the strategy for the rescue. Several attempts were made to land a commando on the cable car, break into the car and winch the trapped people. But strong winds aborted every attempt. Should they wait till next morning?

"No", said Major Ivan Casto, one of the commandos chosen to land on the car and to carry out the rescue.

"Have you any idea of the risk? The winch comes in the way", one of the team members pointed out the danger. (The winch is a roller that has steel cable wound round. Very much like the spool with the string whose free end is tied. The turn of the spool decides how much string the kite gets.)

"I know", said Major Ivan Casto.

"We will be forced to cut the winch if you or the cable that takes you down to the car touches a cable of the car. That will send you hurtling in space, crash in the valley. What hopes have you of survival if that happens?" said the pilots who would stay on the helicopter and try to keep it stable and steady.

Casto pursed his lips and said firmly, "Let us get going".

It was around 5 p. m. The helicopter took off, hovered directly over the cable car. The winch lowered Casto to the top of the cable car. He broke the glass panes of the cable car. The tourists beamed a welcome smile. His presence worked wonders. He got down to work immediately. A fa­ther and his four-year-old son, strapped on to his back, were hauled up first. Four more persons were winched to the helicopter before darkness fell.

The operation was suspended for the day. Casto spent the night in the cable car. His presence worked wonders. Those who remained in the cable car now looked relaxed. Rescue operation was resumed next morning and completed by 10.30 a. m. It marked one of the finest hours for the army commandos and the helicopter pilots.

One could recollect hundreds of such daring feats in which gallant men on board helicopters performed death – defying acts. Each of them confirms the power of courage. Truly has it been said, "Courage conquers".

DARE DEVILS

Courage conquers, we said. Every pioneer displays cour­age of a high order. Each one is a dare devil. Each feat is unique. A quick survey of the history of aviation leads us to more names and events. Let us take note of some of the men and events that made aviation history.

image45The first name that comes to mind is of Sir George Cayley. He tracked down the forces that needed to be con­trolled before one could fly. These were Tift, drag, thrust and gravity’. He developed the controlling mechanisms to counter-balance these forces and thus provide balance to the flying object. He shaped the horizontal rudder (or el­evator), experimented with multiple-wing designs, thought of the propeller. For over forty years, he worked. Finally, in 1849, he decided to test fly his tri-plane glider. He strapped a 10- year-old boy on to the glider and tested it at the open grounds close to his home Brompton Hall. The glider soared in space.

Lindbergh flew across the Atlan­tic solo and created an endurance record. The round the world trip in The Voyager by Dick and Jeana set an­other endurance record. Charles Kingsford Smith tried a different type pig 13 1; Charles of endurance (Fig. 13.1). He became Kingsford Smith

image46

Fig. 13.2: The record-breaking flight round Australia

the first man to fly across the Pacific. He set out, with three others, in May 1928, from Oakland Airfield, US, and landed at Brisbane in June (Fig. 13.2). For him it was a dream come true.

Amelia Earhart was not the first woman aeronaut. That glory belongs to Jeanne-Genevieve Garnerin who soared in space in a balloon. She also was the first parachutist. Mrs. Cromwell Dixon was amused when her 13-year-old son in­vited her to fly an ‘air bicycle’. He told her that she had only to pedal with all the power at her command and she would be taken into flight. She tried that in 1909. She ped­alled hard and the machine took to flight, carrying her along. Therese Peltier, a French sculptor, was the first woman to fly an aircraft solo. Raymonde de Laroach was the first li­censed pilot. She received the licence in 1910. Eighteen years later, Lady Mary Heath flew an aircraft from Cape Town to London. In 1932, Maruyse Bastie of France flew alone, re­mained airborne for 38 hours and created a record.

Flight opened up immense opportunities for the ad­venture seekers.

In 1911, the first major long-distance air race was or­ganised. The route was Paris-Belgium-Holland-England (over the Channel) and back to Paris. There were 43 entries; and 12 different types of aircraft. Nineteen participants com­pleted the first lap. Nine crossed the finish line. Three lost their lives and six were seriously injured. The races, held annually, drew a lot of enthusiastic participants.

In 1913, the Michelin Cup Race set down a challenge for pilots. They were required to cover specific distance and maintain an average speed of 50 kmph. At the Gordon Bennett Trophy, held in the same year, Jules Vedrines’ air­craft recorded a speed of over 160 kmph. It took another seven years to double this speed record. Flying a 300 hp engine, Sach Lecointe registered, at Etampes, speed of over 320 kmph. In 1922, Billy Mitchell broke this record and won the Pulitzer race with a speed of 350 kmph. The quest for speed finally led man to the Concorde (Fig. 13.3). In 1995, the Concorde flew round the globe, taking short halts at Touclouse in Southern France, Dubai, Bangkok, Guam, Honolulu and Acapulco in Mexico before returning to New York, in less than 33 hours.

The quest for more speed demanded improved designs. Often the newly designed aircraft crashed. Accidents took a heavy toll of men and material. But mishaps did not deter the daring. Many young men explored the limits to which the aircraft would go along with them. They performed loops and turns, dipped and rose. Large crowds gathered to watch stunt shows.

Charles Willard, a Harvard graduate, trained under the ace flier and aircraft designer, Curtiss, before he turned to stunt shows. He came to be known as the Wizard. In 1910, he commanded $1,000 per flight. Many others took to stunt shows. But most of them died in accidents. A common say-

ing, in those days, read: "There are plenty of bold flyers; and plenty of old flyers, but hardly any bold old flyers".

In 1913, at a public show, Edouard Pegoud performed death-defying loops in space. The aircraft gracefully arched and turned around, yielding to the command of the pilot. The Press reported the show.

Lincoln Beachey, who revelled in performing spirals and dives with planes, read the news. He decided to try the stunts. He set before Curtiss his plan. He wanted a specially reinforced bi-plane that could stand the strain of sharp loops. The first model crashed. The second one stood the trials. It had a top speed of over 165 kmph. Lincoln Beachey scheduled his show for 14 March 1915. He took off from San Francisco, climbed over the bay toward Alcatraz, reversed course and performed a series of loops, losing height with each one. Back he climbed to 1100 m and dived straight down.

He dropped so low that people could spot his head above the wings. It looked as if he was crashing. But, at the very last moment, he pulled sharply on the stick to regain level flight. That was too much for the aircraft. The wings broke away. The aircraft crashed in the bay. The stuntman was alive, but was trapped in the wreckage. He drowned before he could be pulled out.

After the end of the Second World War, many young fighter pilots were jobless. The more daring among them found work as stunt pilots. They showed their skill at carni­vals. They walked on the wings, while the plane was in flight, or jumped from plane to plane while in flight or got on to aircraft from running cars, ambling up rope ladders suspended from jennies.

In September 1999, Jurgis Kairys, a Lithuanian pilot, displayed a rare stunt. He flew an SU-26 plane at a speed of about 300 kmph under 10 bridges spanning the Neris River at Vilnius, the capital of the Baltic State. It was a risky show. The bridges are just 6 m above the waters. That did not de­ter Jurgis. It took him just under 20 minutes to complete the show. Asked what more he had in mind, Jurgis joked, "The only thing that remains to be done is to fly under all the bridges upside down". Speaking about this show, Jean Louis Monnet, Chief Executive of the International Air Sport Fed­eration, said: "As far as I know, this was the first stunt like this in the world".

In India, the Air Force often organises special air shows. On Republic Day, the aircraft perform stunts over Raj Path. They loop around, fall freely through space, swiftly turn, regain height and vanish into the sky. The aircraft fly in formation, yet not once do they get into the flight path of each other (Fig. 13.4).

A different form of challenge came in with the arrival of ultralight crafts. In 1960, Francis Rogalli developed a light­weight plastic arrowhead shaped flexible wing. He called it

image48

para-sail. It was meant to be a gliding type of parachute for lowering pieces of cargo from high-flying aircraft. It did not find favour with the defence agencies. Acceptance came from an unexpected quarter. Gliding experts picked it up. They rigged a sort of trapeze, spread fabric to form the wing and added a few wires to control flight by shifting weight on trapeze. Thus began the sport of hang gliding. In the mid 1970s, they added small engine and propeller to the craft.

The glider has no wheels, no landing gear. The man riding the glider runs into the wind and takes off. Often the lover of gliding takes the glider to the top of a slope and runs down picking up speed till the glider gets airborne.

Himachal Pradesh holds annual hang gliding competitions before winter really sets in. Hang gliding has become very popular world over.

Is there any room for heady excitement, while we stay on the ground? Radio controlled sailplanes provide this fa­cility. These parasails are very light. Hardly 2 kg, including the radio, placed in a little black box in the nose of the plane! The person on the ground operates the control and defines the flight path.

People who fly the machines, be it an aircraft or heli­copter or glider or parasail, constantly improve designs to break established speed or endurance records. They believe that when it comes to development, even the sky doesn’t set limits.

THE FUTURE IS NOT OURS TO SEE

Innovators know that the future is not theirs to see. The future needs expansion of the vistas of knowledge. That is what they do, continuously. They explore virgin territory that lies currently outside the bounds of knowledge. They dare the untried. Thus they become pioneers.

What further developments await aviation?

Aircraft will become sleeker and lighter thanks to spe­cial adhesives. They make it possible to bond material— aluminium, plastic foam, carved and evened out and cov­ered with fibre glass—better. These materials make the air­craft stronger and lighter. Moreover, they give scope for new shapes to aircraft, shapes that reduce resistance of air by directing the airflow round the plane and not into it. That leads to better speed, lesser fuel consumption. Work is on to harness new material to make the engine lighter and more fuel-efficient. New energy sources—liquid hydrogen, elec­tric power, solar energy and even atomic power—are being tried out.

How will these changes benefit us?

Does it not cheer us to note that some day, in the future, we may be flying our own aircraft! That is no tall story. Look at cars on Indian roads? Did anybody imagine, twenty years back, that the common Indian could own a car? Yet, now, the car is within the reach of the middle class. In the devel­oped nations, smaller planes are owned and used extensively, by citizens. Today is their day. Tomorrow will be ours.

All those who drive through the congested roads of major cities share one dream. If only cars could take to flight, whenever there is a terrific traffic jam! Boeing is working on just this dream vehicle called the electric flivver. It is an airplane-cum-car that takes off easily when it finds itself stuck in’the traffic. Once it gets beyond the stretch of the road that is jammed, it returns to the roads and runs like any normal car. Its gets lift with the help of rotors, fixed on top (very much like the helicopter).

This idea is being extended to develop aircraft that can fly faster than sound and can take off from anywhere. Named, The Transonic Business Jet, this plane will have vari­able sweep wings. These wings, as their name indicates, will sweep forward and backward. They will adjust to the cen­tre of the lift of the aircraft when it flies faster than the speed of sound. While cruising, the wings will be reset at right angles to the fuselage. The plane will be fuelled by liquid hydrogen. Its maximum speed will be about 2,600 kmph.

Ever seen a flying saucer? We are not talking of the saucer that flies in space after we aim it at someone who annoys us. Flying saucers are what aliens, out there in space, use to visit our earth. Or so say those who believe there are intelli­gent life forms out there, in distant galaxies. It is this shape that Boeing finds ideal to serve city commuters. Powered by heavy flywheels that spin in opposite direction, it can take off and land vertically, operate from parking lots in major cities.

Boeing is also working on an amphibious plane. One that can operate from land and water!

These reports cheer us. Then comes another question. Will air travel become faster? Faster than the Concorde that covers the London-New York route in about three hours? The answer is YES! Research is on to fly aircraft at speeds ranging from 4,800 to 12,800 kmph. These aircraft shall fly at altitudes 30,000 m to 39,000 m, where the earth’s gravity is only five-sixth of that on the ground. The aircraft will use jet fuel at speeds up to 5,760 kmph. Then, the turbo engines will shut down, and jet engines, using liquid petroleum, will take over.

In July 2002, Boeing designed a super-efficient aircraft that looks like a giant bat. It has no fuselage or tail, just a huge wing, with a belly that has space to accommodate 480 passengers. The aircraft is so designed that its structure pro­vides the lift. So it will take 32% less fuel and bring the cost of air transport down.

Lockheed has plans to produce a cargo aircraft. It will carry 1,80,000 kg of cargo non-stop to any place on the earth, flying at a speed of 800 kmph. It can fly for weeks, as it will be powered by nuclear energy.

For transport of cargo, another unusual idea is being explored. It is an aircraft with thick wings that shall hold the cargo. The flat bottom of the wing will stay a few feet above water. The craft will fly low, carrying 1,98,000 kg of freight, at a speed of about 480 kmph.

On 30 July 2002, Australian scientists launched a hy­personic ‘scramjet’. It has a revolutionary new engine. The oxygen in the air enters the engine and ignites hydrogen fuel. The aircraft, it is claimed, can fly at speeds of over Mach 8.

These changes will certainly improve civilian transport. They will be suitably adjusted to serve military purposes too.

At the same time, aircraft specially designed for de­fence purposes are in the pipeline. Fighters will carry pow­erful bombs and guided missiles more easily. Rockwell In­ternational launched a bomber, controlled by the pilot on the ground. The idea is catching on. An army general noted, "In the 21st century, we will definitely rely more on pilotless

aircraft to place people out of harm’s way".

Can laser beams propel an aircraft? Scientists at the Tokyo Institute of Technology experimented with laser-pow­ered paper airplane. They are now getting ready to fly tiny pilotless planes. Ultimately they plan to propel planes at several times the speed of sound at high altitudes, where the air is too thin for jet engines to operate. Laser beams from satellites or high-altitude balloons will propel the air­craft.

Laser produces high intensity coherent light waves. Waves remind us of radars that detect aircraft in flight. Can an aircraft evade detection by radar? It can, once we know how the radar works. Radar sends out radio pulses into the flying object. The waves are reflected back to the radar sta­tion. The blip on the screen helps identify the aircraft.

Scientists took note of this fact. Could they distort the reflected radio pulses and thus make it hard for radars to detect the flying object? Then came an idea. An object that has only curves, no flat surface, scatters the waves and dis­perses them in all directions. The scientists exploited this scientific principle. However, this idea gave very limited success. Then came the idea to make all the surfaces of an aircraft as plane as possible, with no surface at an angle that would reflect the waves back to radar. They also developed special paints for the aircraft. These paints absorb some of the radar waves. The end product is the Stealth aircraft.

High altitude surveillance is vital for national defence and for earth study. Lockheeds plans a High Altitude Pow­ered Platform. It will carry cameras and instruments to watch troop movements or identify military installations or esti­mate crop growth or warn about locusts or shifting weather patterns. It will be powered by solar energy.

In July 2001, Helios, a solar powered plane that shall fly for months on end, maintaining a height of 30,000 m, was tested at Hawai (Fig. 14.1). "It is powered by its
shadow", John Hicks, the programme’s manager, joked. Made of carbon fibre, it weighs about 800 kg. It undertakes unmanned flights. It is controlled from the ground. It flies at a very high altitude, far above the clouds. So all day long, it gets sunlight that powers its flight.

Подпись: Fig. 14.1: The Helios Remember Burt Rutan who designed the Voyager? In December 1986, Dick Rutan and Jeana Yeagar flew the air­craft, round the globe, non-stop and created history. Now (in January 2005), Steve Fossett—the first person to circum­navigate the globe solo in a balloon—is all set to perform a similar feat. He will be flying the aircraft GlobeFlyer—solo— designed by Burt. The flight is expected to be completed in 70 hours.

These are developments that we know of. But quietly, silently, secretly (driven by commercial or defence interest), many more advanced designs are taking shape.

What does aviation hold for man, in the days to come? The future is not ours to see. But we have a hunch. One based on reason and logic. Aircraft manufacturers are tak­ing advantage of latest technologies. This is a continuous process. So we can confidently predict the future, say that the aircraft of tomorrow will be faster, more comfortable and sleeker than the ones around now.

On that hopeful note, we end the Great Aviation Story.

STORY

In 1783, men first soared into space, riding a hot-air bal­loon. It was the result of pioneering work by Joseph Montgolfier and his brother Etienne, of Annonay, France. They realized that a balloon, filled with hot air, gained the required upward thrust for flight because hot air is lighter than the air around us.

Could an object, heavier than air, defy gravity and fly? That question remained unanswered, for over 120 years. This was a time well spent. During these years, many people in Europe and the United States experimented with kites and gliders. These experiments proved that objects heavier than air could fly. But nobody knew how to engineer a flying machine that would remain airborne.

Many people tried and failed. Failures, it is said, are stepping stones to success. Each failure brought out a few more insights into what more had to be done to make the dream come true.

Finally, two young men, Wilbur Wright and his brother Orville Wright, found the answer. They became the first men to fly a machine that was heavier than air. The machine was crude, unsophisticated, yet it flew.

That event marked the beginning of the great aviation story. Daring men and women explored the frontiers of the aircraft’s range and speed by designing shapes and engines based on latest technological advances. The explorers have not reached the end of the road, either. They are still hot on

the chase of ways and means to take the aircraft to new records in speed, safety, style and elegance.

Aircraft, however, have one limitation. They can’t take off or land almost anywhere. They need long stretches of runways. The search for an alternate machine that would take off and land vertically led to the invention of the heli­copter.

Innovators are working on furthering the style, design and performance of the aircraft. They predict still more spec­tacular developments in aviation, in the years to come. Some say that sky is the limit. Others assert that even the sky can’t set the limit to the future of aviation.

This book is history, with a difference. This is history, where facts have been touched up with the liberty of a crea­tive writer. This presents the great story of aviation.

THE DREAM AND THE QUEST

Early man was perfectly at home on land. But water and air remained hostile.

Water could not hold him back where it was shallow. He just waded across. But he was scared to take on rivers in spate or lakes and seas. It took him quite some time to learn to swim. By flexing his limbs, he stayed above water and steered himself across. But this was tiring.

He watched logs of wood floating in water. That gave him an idea. He sat atop a log. It stayed afloat. He rode a log and forded a river in spate. It was easy. It did not tire him out. Thrilled by that experience, he shaped logs into small canoes. Canoes gave him room to sit and work the oars. He made boats of wood or reeds and sailed the high seas. Then came ships that sailed by wind power. Soon mo­tor boats and steamships took man across high seas. Water didn’t limit his movements any longer.

Man watched birds in flight. "If only I could be as deft as birds, wing my way to where I want to go!" he wished.

Man studied birds. Many facts came to light. He made a note of them: "Every bird has wings. It flaps the wings and flies up or down. The kite flaps its wings, soars to great heights, spreads its wings, stops flapping them and glides gracefully".

His studies gave wings to his imagination. He shaped angels after the human form, and lent them wings. For he believed that wings held magical powers. Those with wings could fly.

Greek mythology tells us of Bellerphon. He rode Pegasus, the winged horse, and flew toward Mount Olym­pus, the abode of gods. This place was out of bounds for man. But Bellerphon ignored the rule. Zeus, the Greek god, sent shafts of lightning. Pegasus lost its wings and thus its ability to fly. It crashed to the earth, taking Bellerphon to his doom. He became lame and blind and wandered aim­lessly till death.

Another tale tells us of Daedalus, a great inventor and engineer and a favourite of King Minos. But no one remains a favourite at court, forever. The King took offence, at a few casual comments of Daedalus, and sent him and his son Icarus into exile in the Island of Crete. Daedalus gathered feathers and used wax to glue the feathers together. He pre­pared two pairs of wings, one pair for himself and another pair for his son. He warned his son not to fly too high since the wax would melt in the sun’s heat. The feathers would drop off, the wings would be damaged and flight would become impossible.

The two took off. Icarus kept right behind his father, for some distance. Then he let caution to the wind, dipped and rolled, had fun time. How high could he fly? He wanted to find out. He soared, higher and higher, and got closer to the sun. The wax melted. The feathers flew off and Icarus crashed to his death.

In Indian mythology, Ravana abducts Sita in the Pushpak Viman. We think of it as a flying chariot. In the fa­mous work, Arabian Nights, there is the reference to the fly­ing carpet.

These tales have their roots in man’s desire to fly. Wings held the key to flying, man concluded. He worked on this idea.

In ad 1130, the Benedictine Monk Elmer of Malmsbury, Wiltshire, attached wings and took off from a mount. He crashed and broke his legs. He was lucky. Not so lucky was

Giovanni Battista Danti. In 1530, he tried to fly with wings, but came down a cropper. He paid for his misadventure with his life. Men like Elmer and Danti didn’t know that wings, per se, don’t give one the power to fly. He needs matching muscle power to lift him in the air and to flap the wings to keep him in flight. Scientists now know that no animal has that much muscle power.

Подпись: Fig. 1.1: Francesco de Lana-Terzi's flying machine Leonardo da Vinci, the famous artist, was an innova­tor too. He too wanted to fly. But he was not foolhardy. He noticed that objects, heavier than air, flew for very short duration. But gravity slowed them down and forced them to the earth. He studied the design of the boomerang used by the aborigines of Australia. He read about gliders, popu­lar in China. He watched birds in flight. Slight movement of the wing or tail helped eagles glide in space on air cur­rents without flapping the wings. Da Vinci sat down and drew pictures of wings and tails of various birds. He de­signed a birdlike flying machine. Can a machine take off verticall? He tried the airscrew machine, which is the forerunner of the helicopter. He tested the design of a parachute.

Heavy objects drifted slowly to the earth when held by strings, above which spread huge cano­pies made of cloth.

In 1670, Francesco de Lana-Terzi guessed that objects needed im­mense buoyancy to resist gravity. He designed a ""’ying mac’ ine wi ’ a ship’s hull, a mast and
four globes out of which air had been pumped out to make them lighter. It didn’t fly. But he was on the right track (Fig. 1.1).

Man didn’t have enough muscle power to flap the wings fast enough to gain buoyancy. Could machine pro­vide the power needed to fly?

Подпись: Fig. 1.2: George Cayley Sir George Cayley got a bright idea. "Success in flight would come", he said, "by making a sur­face support a given weight by the application of power to the resist­ance of air" (Fig. 1.2). In 1853, he built a glider. Its wing surface was 200 square feet. It had three pair of wings and a tailpiece. The wings curved more on top than on the bot­tom. (This design was backed by Bernoulli’s principle. An object, with a flat base and a curved top, reduces air pressure on top. This results in upward thrust). Cayley mounted the glider on wheels. It had room for a man. Cayley’s coachman got on to the glider. The glider was pulled fast across a vast open ground. It gained the speed needed to take off.

image6William Henson hailed him ‘The Father of Aviation’. He improved the design of Cayley by adding two pusher propellers and managed a short flight. He dreamed of air travel to Egypt and beyond. That ended as a pipe dream. He moved to America and spent his life advocating further research into aviation.

Alphonse Pen produced working models, powered by twisted rubber Fig. 1.3: Otto Lilienthal motors. They had only one flaw. They

didn’t remain stable while taking turns. For that he needed moving wings. Otto Lilienthal (Fig. 1.3) shaped gliders whose wings could be bent and manipulated to maintain stability. He prepared a ‘Flying Hill’ of bricks, about 12 m high, to serve as his launching pad. He said he could fly regardless of wind’s direction. He made over 2000 flights. His flights were photographed (Fig. 1.4). All went well till 9 August 1896. On that day, Otto took off in the glider. He soared into space. Suddenly the air current weakened and the glider lost movement. Otto shifted his weight, hoping to gain support for the glider from the air current. The glider nose-dived. Otto suffered grievous inju­ries and died that night. His last words were: "Sacrifices must be made".

In 1896, Samuel Langley made two models. They gained lift with the help of a houseboat steaming down the Potomac River. The models flew well under normal condi­tions. In 1903, Langley built a full-size machine. It had a wingspan of about 15 metres and was powered by a gaso­line engine. Langley tested it twice, once in October and again in December 1903. On both occasions the engine failed. The flying machine was dumped into the river. Langley came very close to success. But success eluded nim.

Yet within a few days of Langley’s unsuccessful at­tempts, two young men, Wilbur Wright and Orville Wright, sons of a priest, reached the winning post.

WRIGHT BROTHERS IN THE RIGHT

Father Milton Wright, the Bishop of Dayton, Ohio, fumbled with the latch of the wicket gate with one hand while clutch­ing a fairly large – sized parcel in the other. His sons Wilbur and Orville noticed him, raced to the gate, lifted the latch and held the gate open.

"Thank you, my boys", Father Milton Wright beamed a happy smile, handed the parcel to Wilbur and said, "That is for you, boys". Wilbur and Orville ripped the packet open. They screamed with joy when their eyes fell on the toy heli­copter. They played with it. Its movements roused their cu­riosity. Their quest for more information on flying led them to mythological stories and from there to reports and records of the work of pioneers who had taken the quest forward.

On an earlier occasion, Father Milton had gifted bicy­cles to the two boys. Cycling had become an obsession with them. They cycled the countryside, sped along the alley­ways. They hardly found time for regular studies.

"What do you propose to do?" Father Milton asked them, once it became clear that they didn’t do well at school.

"We plan to open a cycle repair shop", Wilbur replied.

"Whatever you do, try to be the best. Be honest in your dealings. Be friendly to people. Earn a good name", the Bishop gave his assent.

Wilbur and Orville set up a shop. They always did a good job. They were polite to the clients. Their charges were reasonable. So their business flourished.

In their spare time, they fabricated more efficient bicy­cles. They had easy access to wheels and spokes and ribs to create new designs. Often they rode their new designs, over long distances, getting a measure of the resistance that wind exercised, when the vehicles moved fast. These escapades gave them clear insight of wind force and air currents. This knowledge stood them in good stead when they set out on the quest to fly.

They got a copy of the book, Progress of Flying Machines by Chanute and read it several times. It taught them how to prepare models of kites and gliders.

In May 1900, Wilbur wrote to Chanute, "For some years, I have been afflicted with the belief that flight is possible to man. My disease has increased in severity and I feel it will soon cost me an increased amoun.^of money, if not my life".

Chanute encouraged him to continue the work.

The Wright brothers spent all their spare time, testing gliders. They conducted more than a thousand test flights. Some of these tests were in wind tunnels, specially made to match the behaviour of gliders under varying wind condi­tions. These experiments taught them the importance of the direction of the wind and the speed of the air current in controlled flight. Their success would depend on choosing a suitable site where wind conditions would be favourable.

From the United States Weather Bureau, they obtained a list of ‘windy, treeless, level’ sites. They examined the suit­ability of each of the sites. Finally they selected the sandy Kill Devil Hills, 6 km south of Kitty Hawk, North Carolina.

On 5 September 1900, Wilbur and Orville rode to the site and set up camp. Wilbur observed birds in flight, for several days. He noted how birds adjusted to wind direc­tion and air currents. They tilted the wings to change flight path or to take turns. That gave him the idea for moveable wings. "Thus the balance could be controlled by utilising dynamic reactions of the air instead of shifting weight",

Wilbur noted. This led to ‘wing warping’, a concept in use on aircraft even today. Wilbur and Orville patented this de­sign later.

"Can’t we mount a gas-driven internal combustion engine on a glider? It should work", Wilbur turned to Orville and Charles Taylor, a friend. He was also a good mechanic, who helped the brothers in their experiments.

"It should", Charles replied, spontaneously.

"It should, if the engine is light and hardy", added Orville.

The three men searched for long for a suitable engine. None was available. So they set down to fabricate an en­gine. They cast the engine’s body and the crankcase out of a single piece of very thin, light aluminium-copper alloy. It was a four-cylinder 12 hp engine, fuelled by gasoline.

Wilbur and Orville prepared the blueprints for the airplane and started fabricating it. It was a model with four wings. (That made it a biplane. Monoplanes have two wings). The wings were made of wood and covered by tough linen. Reinforced wires joined the wooden struts. The wires ran from a cradle-like device, on the lower wing. The cradle provided room for the pilot. It served as the cabin. He could lie in this cradle and shift his weight around to move the tips of the wing up or down. A tail rudder was added to provide stability while taking turns. Two pusher propellers were linked to the engine by bicycle chains.

At last, the brothers were ready to fly the crude con­traption. They called it, The Flyer. Preparations began in right earnest for the flight. Hard wooden rails were laid on the sloping hills. On it rested a trolley with wheels. The airplane was loaded on it. A cable connected the trolley to a pulley on top of a tower. Its free end ran over the pulley and was held down by weights. Once the weights were removed, the trolley would slide down the slope, pick up speed and provide the necessary thrust for the aircraft to get airborne.

image8

Fig. 2.1: The Wright brothers’ Flyer (1903)—first man-carrying powered sustained flight.

On 14 December 1903, Wilbur climbed on to the lower wing and lay flat on his stomach. His hips slid into the pad­ded wing-warping cradle. Orville made the last-minute ad­justment to the motor. The propellers provided immense thrust. Orville and a friend, Will Dough, released the weights. The trolley rolled on, picked up speed. Orville ran beside the plane, balancing it with one hand.

The Flyer lifted off (Fig. 2.1). Wilbur pulled the elevator sharply upward. (The elevator is the control mechanism that helps the pilot gain or lose height according to need. Lay men refer to the elevator as the rudder.) The aircraft surged to a height of 4.5 m before losing height. Wilbur was not quick enough to turn the rudder down. The aircraft sank to the ground, its nose up in the air. It had been in the air for just 3.5 sec. In the excitement, Wilbur forgot to shut the en­gine off when it hit the ground. The Flyer dug deep into the sand, splintering a strut and also a brace of the elevator.

This was too brief a flight to bring cheer to the two men from Dayton. They set out to repair the aircraft and make it fit for another trial. It took them two days.

"We are ready", Orville looked up, picking a few strands of wire that lay on the sand dune.

"Tomorrow will be our day", Wilbur came from under the belly of the aircraft, after making the final check of the wheels.

"I’ll alert John Daniels, Will Dough, Adam Etheridge and Bob Westcott to be present. This time, the aircraft, I hope, will stay up for a longer duration", Orville expressed his wish.

That night, they could not sleep. Their thoughts hov­ered around the grand show, scheduled for the morrow. They tossed around in their beds, dreaming of the future.

Gusty cold winds marked the dawn. But, by 10 a. m., the wind speed fell to about 30 kmph. Orville, Wilbur and the four witnesses hurried over to The Flyer, which rattled in the wind. "Heads I win. And tails you go", Wilbur pulled out a coin and tossed it up. The coin spun in space, came down and rested ‘Tails up’.

"Congratulations, Orville. You fly first today", Wilbur smiled at his younger brother.

Orville climbed on to the lower wing, lay flat on it, and pulled the bicycle chain that started the engine. The

propeller roared. The plane purred with life. Wilbur ran long, while Bob Westcott clung to a stopwatch. Daniels adjusted the camera, ready to record the historic flight. Etheridge and Will Dough removed the blocks in front of the skids of the trolley. The trolley picked up speed. The aircraft’s propeller rotated fast, giving the necessary thrust. The Flyer rose with a shudder. Soon it gained a height of about 3.3 m. For 12 sec it remained airborne, covering a distance of 36.3 m (Fig. 2.2).

The aircraft was taken back to the starting point. Now Wilbur got on. He flew a distance of 53 m. The timing could not be recorded. Orville flew next, covering 55 m in 15 sec. On the fourth attempt, Wilbur flew 200 m in 59 sec.

Next day, The Virginia-Pilot reported the event in head­line:

NO BALLOON ATTACHED TO IT. TWO YEARS OF HARD, SECRET WORK

BY TWO OHIO BROTHERS CROWNED WITH SUCCESS. WITH MAN AS

PASSENGER HUGE MACHINE FLEW LIKE BIRD UNDER PERFECT

CONTROL.

The report began with the words, "The problem of aerial navigation without the use of a balloon has been solved". It described Wilbur as ‘well-groomed, raven-haired and swarthy with piercing blue eyes’. Orville was ‘sandy­haired, with sparkling blue eyes’ (Fig. 2.3).

It was a small beginning. Yet it was a major triumph. Years later, Orville noted, "I would hardly think today of making my first flight on a strange machine, even if I knew that it had already been flown and was safe. After these years of experience, I look with amazement on our audacity in attempting flights with a new and untried machine".

Who would have heard of Wilbur and Orville if they had not been audacious and had lacked the courage to try the untried? If they had not dared, the credit for such a flight would have gone to Alberto Santos-Dumont. But that is another story.

з

CROSSING THE ENGLISH CHANNEL

Santos-Dumont had already won the Deutsche prize of 1,00,000 Francs, flying an airship (balloon), around the Eif­fel Tower (Fig. 3.1). He now turned his attention to gliders and kites. Could he install a motor and steer them along? How would such flights be different from those on dirigi­bles (balloons powered by motors)? The possibilities seemed immense. So Santos-Dumont resolved to master the art of flying a giant kite, powered by a motor. He read all avail­able material on kites and gliders. Soon he was familiar with their designs.

Among his friends were professors and engineers. They educated him on the role of aerodynamics in designing kites. They suggested a box-type kite. The frame would be made of wood. The body would be covered with muslin. The en­gine would be suitably mounted. The kite would fly tail first.

Santos-Dumont spent a huge sum, designing the kite. Alas! He didn’t know that the Wright brothers had beaten him in the race for honours. In September 1906, he was ready to fly a giant box-shaped kite. It had two sets of wings and was mounted on bicycle wheels. This, the designer said, would facilitate smooth landing. An eight-cylinder Antoinette engine was installed. The kite got airborne. It flew, tail forward, for 8 sec, covering a distance of 11.3 m. The landing was smooth. On 12 November 1906, Santos – Dumont repeated the experiment. He flew 155 m in 22 sec.

image11

This won him a prize of value Rs. 20,000. (Quite a tidy sum, in those days.)

Everyone hailed him as a pioneer. Santos-Dumont be­lieved he had created history. He basked in the limelight, but this euphoria did not last long. He learnt of the Wright brothers and of their flight, at Kitty Hawk, in December 1903. He had struggled against all odds, only to come second in the race. That was a severe blow.

But he was the first man to circle the Eiffel Tower in a dirigible. That gave him some consolation. It assured him a place in the roll of honour in the history of aviation.

In 1909, Lord Radcliffe of The Daily Mail, London, of­fered a prize (value about Rs. 1 lakh then) to the first man who flew an aircraft across the English Channel. Many young men considered the offer, but backed out when they became aware of the grave risks.

No standard aircraft was available. So anyone who wanted the prize money had to prepare a flying machine on his own. Few people had the skill and the money to do that. Moreover the weather over the English Channel was
unpredictable. Gusty winds and spiralling air currents could toss the aircraft around, tear it apart; or the engine could get flooded with gasoline and stop working.

Подпись: Fig. 3.2: Louis Bleriot The risk was worth taking, thought Louis Bleriot, of France (Fig. 3.2).. Flying was his hobby. He was a daredevil. Many were the tum­bles that he took during his previous flights with kites and gliders. He had broken his skull; pulled his calf mus­cle; limped for a fortnight after being thrown out of a glider, as it came in to land; received hard knocks and se­vere bruises on several occasions.

These painful experiences, however, did not dampen his love for flying. He returned to fly after periods of enforced rest, after the mishaps.

Bleriot heard about the prize. He designed a mono­plane. (Each wing had a span of 7 m), mounted on three wheels, two in front and one in the rear. A three-cylinder Anzani engine provided the power. It was ready by the middle of July 1909. Bleriot made plans to take off from the open ground at Le Baraques, Calais.

Hubert Latham, a leading flyer of France, too was after the prize money. He set out from Sangatte near Calais on 19 July 1909. The engine developed trouble while flying over the Channel. It spluttered, coughed, went into convulsions and then ceased to work. The aircraft lost height. Latham landed on choppy waters. A French naval vessel rescued him. He tried and failed.

Latham would try again, thought Bleriot. He was still on crutches, after a recent accident. Yet he decided to take the challenge. He told his friends, "It’s only a short flight. It shouldn’t take more than forty minutes. So please keep watch. When the weather holds good, I shall fly".

Bleriot was still in bed at 3 a. m. on 25 July 1909, when he was woken up by sharp knocks on the door. He sat up in bed. The pounding on the door continued. It took Bleriot some time to get hold of the crutches, adjust them and hob­ble to the door. Framed against the door stood a friend.

"Good Morning. We’ve been told that the weather shall hold today. So…" the friend walked in.

"Wonderful. I shall be ready in a minute", Bleriot hur­ried to the bathroom.

Bleriot took the monoplane, the BLERIOT XI, on a test flight, circled the ground twice and came back for gas. After filling the fuel tank, he restarted the engine. His friends crowded near the cockpit. He shook hands with them. As they drew back, he pulled the throttle. The aircraft rolled on, picked up speed and took to the air gracefully (Fig. 3.3). The men on the ground cheered. Someone checked the time. It was 4.35 a. m.

The aircraft flew at a height of 75 m. A French naval ship sailed the Channel, keeping an eye on the aircraft. It was assigned to help Bleriot in case his aircraft developed trouble and he was forced to land on the waters.

Bleriot felt right on top of the world as the aircraft flew

over the Channel. He flew so fast (64 kmph) that the ship was left far behind. He had no compass and did not know whether he was heading in the right direction. He was half way through when the engine hissed. It was getting heated. A nameless fear gripped him. Would the engine fail him, force him to down his aircraft in the waters of the Channel?

He felt a blob of water on his cheek. He reached out for it, and his hand became wet with raindrops. The rain came just in time. It cooled the engine. The aircraft flew on, without any further trouble. Bleriot sighted the cliffs of Do­ver, to the west of his flight path, and changed the direc­tion. The aircraft now pushed against the wind, headed to­ward Dover. Bleriot touched down on a green field, at Northfall Meadow, just behind Dover Castle. (It was close to the spot from where two balloonists, Dr Jeffries and Blanchard, had undertaken the first balloon flight across the Channel, more than hundred years back). Bleriot won the prize and the laurels.

A month later Bleriot entered the Great Air Meet at Reims in France. He competed with more than 30 pilots. But he lost. Glenn Curtiss of the United States recorded a speed of 77 kmph and won top honours (Fig. 3.4). It was one more feather in Glenn’s cap. Earlier he had bagged prizes offered by the Scientific American and the New York Aero Club.

The organisations wanted to find out how much con­trol man had gained over the aircraft. Could anyone fly on a day, specified in advance? Could he cover a distance of at least 1 km? Such a man deserved the prize. Curtiss accepted the challenge. He announced in advance that he would fly on 4 July 1908 (National Day of the United States).

But, 4 July 1908 turned out to be a wet and rainy day. Yet a large crowd collected at the venue. They waited, with umbrellas, raincoats and parasols protecting them from the rain. It rained the whole day. Only around sunset did the
sky clear. Curtiss climbed into the cockpit of his plane, the June Bug. He started the motor, opened up the throttle and nudged the aircraft into flight. He groaned when the flight ended after covering less than 1 km.

Подпись:He tried again. This time, he covered nearly 2 km. Sweet were the fruits of success. Curtiss savoured his victory.

He had proved that one could fly at any time of one’s choosing.

Could the aircraft help national defence? Experts studied the possibil­ity. But they didn’t bring a sense of urgency to the task. For the world was at peace. There were minor skirmishes, but they didn’t streak the sky with war clouds. An assassina­tion whipped up the power needed to herd in the clouds to darken the scene.

WINGS INTO WAR

Peace claimed its victims. The victims were young, daring fighter pilots. They were demobilised, knocked out of ac­tion. But the knocks did not leave them down and out. Many of them found new areas of activities.

John Alcock and Arthur Witten-Brown had served the Royal Air Force as fighter pilots (Fig. 5.1). They did not like being grounded. How could they get a chance, once again, to fly?

Alcock heard, while spending an evening at the club, in late 1918, with a friend, of a prize of 10,000 pounds of­fered by the Daily Mail to the first person to fly non-stop across the Atlantic.

image22"This is one flight I can undertake. If only I can find a sponsor, who gets me an aircraft and also provides funds to equip it…" Alcock didn’t complete the sentence.

"That shouldn’t be a prob­lem", the friend mumbled.

"So, where do you see a problem?" Alcock said edgily.

"It’s a mission fraught with danger", the friend warned.

"That’s the least of my Fig – 5.1: John Alcock and worry", Alcock Smiled wryly. Arthur Witten-Brown.

"I’ll make a bid, if I get necessary backing", Alcock replied.

He discussed the matter with Arthur Witten-Brown, a former RAF fighter pilot, and asked, "If I ask you to fly with me?"

"I’ll jump at the offer", Brown responded with joy.

"That’s a deal", Alcock reached out for Brown’s hand.

A checklist of possible patrons was prepared. This list helped them find support for their project.

Which aircraft should they fly? They remembered the Vickers Vimy biplane, which they had flown during the war on bombing missions. It was a large plane, powered by two Rolls-Royce engines. It had speed and strength.

"WeTl have to fly from the American end", pointed out Brown.

"I know. Air currents make a flight, across the Atlantic, heading toward Europe, easier", Alcock smiled.

The two got hold of a bomber, dismantled it and carted it, in sections, to St. John’s, New Foundland, and set up camp (Fig. 5.2). The site for assembling the aircraft lay at an open ground called Mundy’s Pond. The two secured assistance of a handful of enthusiastic mechanics and reassembled the aircraft. They attached additional fuel where the aircraft once ’ carried bombs. Some space for storage of fuel was provided in the wings too (Fig. 5.3).

image23

Fig. 5.2: Vickers Vimy bomber

While these preparations were under way, the Ameri­can Navy launched a hopping flight across the Atlantic. Curtiss co-ordinated the technical details of the flight. Lt. Commander J. H. Towers led the group of four seaplanes.

Seaplanes and flying boats take off and land on water. Due to lack of runways, normal airplanes could not operate as passenger carriers. The seaplanes and the flying boats, therefore, were used extensively to transport people around till about 1950.

The seaplanes set out on 8 May 1919. One of the planes developed problems and dropped out. The others, after a few halts, reached Lisbon on 20 May. A week later, they flew to Plymouth, England. It was not a non-stop flight. So Alcock and Brown were not unduly upset.

Cause for worry came from another source. At St John’s, two daring pilots, Harry G. Hawker and Mackenzie Grieve, were making the final preparations to fly a single-engine Sopwith biplane across the Atlantic. They set out on 18 May 1919. Alcock and Brown cursed their fate. Had they come so far, only to be beaten in the race by their competitors? That thought nagged them, while they waited for further reports of the flight of the Sopwith.

image24

Harry G. Hawker and Mackenzie Grieve flew toward the Irish coast. The engine coughed and spluttered after covering about 1,800 km. The deep blue stretch of the sea menacingly closed in as the plane lost height and tumbled into the waters. A tramper rescued the bobbing men from the waters. Thus ended their bid for the prize.

The news lifted the spirits of Alcock and Brown. They hurried with the final preparation.

14 June 1919 was a bright sunny day. Reports indicated that the weather would hold, for some time. Of course, no­body took such predictions seriously. The weather could turn bad, suddenly, without warning. The two pilots got into the cockpit. Alcock started the engine. He pulled the throttle. The aircraft raced along the bumpy, uneven field. The wings, laden with fuel, drooped. The aircraft lifted off, sluggishly, just a few feet before it reached the block of trees that cir­cled the field. The aircraft skimmed inches above the trees.

For a couple of hours, the aircraft was nudged faster by the tailwind. That gave an added 64 kmph to the normal cruising speed of 145 kmph of the aircraft.

The first setback for the fliers came when the radio conked off. Thus the plane’s communication line was snapped. Soon, the airplane began to rattle. A quick check by Alcock made him shiver. The exhaust of the right engine had cracked. It was quivering as if mad, while tongues of flame danced around the crack. For a moment, Alcock thought it marked the end of their mission. Then hope surged up. He told himself, "We’ve weathered many a storm, during the days in the RAF. So, even this threat may pass".

It did pass. But soon the plane ran into massive air turbulence. Vertical air currents spun the plane, viciously. The plane lost height. It came as close as 20 m of the sea. Alcock pulled at the stick, frantically. The plane quivered. Then its nose rose and Alcock and Brown sighed in relief. The plane regained altitude.

John Alcock steered the plane above the clouds and the fog. The plane faced a new danger. Sleet and snow hit the plane.

Подпись:The roar of the en­gines was loud.

The two men could not even talk to each other, find out how they could face the threat.

Brown acted on his own. He grabbed a knife and climbed out of the cockpit, crawled over the right wing, got close to the engine and scraped the blocks of ice that coated the engine (Fig. 5.4). Back he went to repeat the operation with the sec­ond engine. It was a very risky operation. A sudden gust of wind, a surge of air current would have sent Brown plum­meting into the icy waters, below.

Alcock decided to fly at a lower altitude. The fog had cleared. For seven hours, the weather tested the limits of endurance of the pilots.

At last, it was day. Visibility was good. Brown scanned the scene ahead of him. Suddenly the southern tip of Ire­land came into view. Brown could not contain his joy. He screamed, above the roar of the engines. But, Alcock could not make out what he was saying. He could only notice Brown holding out the hand, pointing toward a hazy curved line beyond the waters. The sea seemed to be kept back by the hazy line. Beyond the line lay land, the Irish coast. That

awareness touched his lips with a thin smile.

Alcock checked the maps, read the compass and made quick calculations. The plane was heading toward the small town of Clifden, some distance off Galway, the original tar­get the pilots had set.

Alcock circled the land. Brown spotted a vast ‘open ground’. Alcock started the descent. The aircraft touched down, in the centre of a muddy patch. The wheels of the aircraft lay buried in mud. Quickly, the two men on board the aircraft got out, splashed their way through the mud and reached firm ground. "That’s it", Alcock hugged Brown. The two stood, with tears of joy streaking down their cheeks. It was their moment of triumph. They had crossed the At­lantic without a halt in between.

This triumph made them heroes. Wherever they went, large crowd mobbed them. Young boys and girls crowded around them, seeking autographs. Cameras clicked, catch­ing their profiles on films for eternity. They received the prize money. That cheered them. But happier still were they when the King of England knighted them, at a special function at the Buckingham Palace.

In 1914, the Archduke Ferdinand of Austria was assassi­nated. The tragedy rocked the whole of Europe. War clouds gathered. Efforts to avert a war failed. The Astro-Hungar – ian Empire, Germany and Turkey, formed a group. Pitted against them were the Allies, composed of Britain, France, Russia, Italy, Japan and the United States. First World War broke out.

Nations at war have, since time immemorial, adopted many strategies to gain their ends. Among them, the effort to gather information about the enemy’s strength and for­mation remains vital. It was so during the First World War too.

Field scouts fanned out, sneaked, as close as they could, to the enemy lines. They stayed beyond the firing range of the enemy, watched through telescopes and gathered infor­mation.

Manual scouting almost ended when machine guns, invented by Fliram Maxim, came into use. The enemy de­fended his camps with machine guns. The scouts could not get close enough to gather information.

On earlier occasions, balloons had been used for aerial survey of enemy positions. Could not aircraft perform the job better? The possibilities seemed immense. Both sides started working on this idea. The existing aircraft were re­designed. Additions and alterations made them sleeker, faster and easier to fly. The cameras on board recorded

enemy formations and camps while the aircraft flew at heights well beyond the range of guns on the ground. Aerial reconnaissance became the order of the day.

How could enemy snooping be stopped? Instructions were issued to designers of aircraft to come up with ways and means to stop the predators. They considered various options and finally came up with a single-seater fighter air­craft, equipped with guns, to intercept and down enemy aircraft, engaged in aerial survey.

image15This was just the beginning. Soon came a brilliant idea. Can’t single-seated aircraft fly over enemy territory and drop bombs? That marked the birth of bombers. New designs improved the speed and manoeuvra­bility and fighting power of the air­craft.

The air was no longer a safe place. In March 1915, Raymond Saulnier invented a bullet deflection device (BDD). It was tacked to the propeller of a monoplane. Powered by a rotary engine of 110 hp, it had a maximum speed of 165 kmph and flew at an altitude of 2000 m. The

image16

BDD timed the gun to fire when the Fig. 4.1: Rolland Garros

image17

Fig. 4.3: Fokker monoplane

rotating blades were not in the way of the gun. This device proved very effective. Roland Garros (Fig. 4.1), a French pi­lot, used this device to shoot down three enemy aircraft during one mission (Fig. 4.2).

The Germans were not far behind. They developed the Fokker, a small aircraft (Fig. 4.3). Its top speed was 130 kmph. A fleet of 50 such aircraft went into action against the Al­lies. They turned out to be a real scourge. Aerial bombing caused severe damage to people and property. The English and the French reeled under the attack.

German designers produced special types of aircraft to serve specific needs. Training for pilots became scientific

image18

and systematic. Pilots mastered the art of flying in forma­tion. This led to development of Squadrons with defined duties. Repair centres were also set up. Germany continued to make headway in exploiting the air power.

Britain and France found the answer to the Fokker air­craft in new designs. In 1915, Capt. Geoffrey de Havilland produced the D4-2. It could fly at a speed of 140 kmph. The Fokker could not match it in speed and dexterity. The Germans, in turn, improved on the French aircraft Neuport and produced Albatros D-l (Fig. 4.4). It had dual machine guns, with double the fire power, mounted near the cockpit. The Albatros carried out attacks on Britain in April 1917. (Historians refer to the period as Bloody April). England lost 151 planes; Germany just 51. German bomb­ers, called Gothas, carried out aerial bombing even during the day. The Allies were unequal to this assault. The chances of holding back Germany looked bleak.

Then came the turn of fortune. The United States joined the Allies. Britain designed the Sopwith Camel, an excellent fighter aircraft (Fig. 4.5). The Bristol Fighter and Spad XIII were two new aircraft that strengthened British air strength. Germany refined the Fokker to produce the Fokker D VII,

image19

with a maximum speed of 192 kmph at an altitude of 7,000 m.

Most of the aircraft had limitations. The Gothas were tail-heavy. So pilots had trouble keeping the aircraft steady at landing. The lower wing of the Albatros twisted easily while the aircraft dived. All aircraft shared one danger. Of­ten the fuel tank caught fire. Pilots didn’t have parachutes. So they could not bail out when their aircraft were hit. They faced a fiery end. Often they shot themselves before the fire got to them.

The War proved the importance of air power in war. The men who headed Britain’s War Office realised this and held meetings to debate the issue. These deliberations led to the formation of the Royal Air Force on 1 April 1918.

That marked the culmination of a small, hesitant start made in 1908. In the same year, on 16 October, the first British Army Plane, designed by Cody, flew a distance of 410 m. That was just a flash in the pan. After the flight, a cost study was undertaken. The project had cost over 2,500 pounds. That was considered too high. Further work on the aircraft was shelved and the factory shut down.

However, within a year, Britain received a new jolt. Louis Bleriot flew across the English Channel. That flight was an eye-opener for the British. For centuries, the people had looked upon the English Channel as a God-given defence, a natural moat. It had warded off attacks by sea, on several occasions in the past. Bleriot’s crossing of the Channel marked the end of the Channel’s invincibility. The Channel could not provide any defence against air attack.

Around this time came reports of progress by France and Germany in aviation. Bleriot, Deperdessin, Morane and Farman, four French companies, took the lead in the pro­duction of aircraft. Britain could buy French aircraft. But that would leave Britain dependent on the French. Self-reli­ance became the need of the hour.

The old factory was re­started. Geoffrey de Havilland, who had the requisite expertise, joined the factory as designer and test pilot (Fig. 4.6). He de­veloped the two-seater biplane model B. E. 1. It was improved and developed as the B. E. 2 (Fig. 4.7).

The War ended. The Allies won. Peace returned. Hu­man development needed more funds. Investment in de­fence came in for pruning. Would it affect the progress of aviation? It could have but for the farsightedness of Winston Churchill (he later became Prime Minister of England and

led the nation to victory in the Second World War), who was the Secretary of State for both War and the Royal Air Force (RAF). He backed the RAF to the hilt, encouraged es­tablishment of schools to train pilots. Mock fights and air stunts won public backing to the Air Force.

The pilots did not remain idle. The RAF saw action in campaigns against tribals in British colonies. It flew in to contain troubles in Iraq in 1922. In 1928, tribal groups of Afghanistan, led by Kabibullah Khan, rose in revolt. The men surrounded the British Legation at Kabul and took 586 people as captives. How could the captives be rescued? The terrain was mountainous, rugged, mostly snow-covered. Wild winds swirled around. The Royal Air Force was as­signed the task of airlifting the captives. The pilots rose to the occasion. The operation was truly hazardous. The weather was unpredictable. The terrain was hostile. Yet the pilots completed the rescue, despite ceaseless gunfire from the ground.

Each successful operation gave a stimulus to research in aircraft design. Powerful engines and new designs en­hanced the speed and range of aircraft. The First World War had given a big boost to aviation.
