Turboprops in Airline Service

Until Viscount 800s began flying with Continental Airlines on May 28, 1958, turboprop airliner service

within the United States was limited to points east of the Mississippi River, where Viscount 700s flew in the colors of Capital Airlines, which assured the type’s suc­cess with a massive order for 60 airplanes. From north of the border, Trans-Canada Air Lines brought its Viscounts into airports at Boston, New York, Detroit, Chicago, and Seattle.

Based at Boston, quasi-regional-carrier Northeast Airlines took a small fleet of 10 Viscount 700s in lieu of a failed Bristol Britannia order, and enjoyed competitive

success with the type on shorter segments, including the dense Boston-New York-Washington commuter run. This then was the immediate Jet Age effect that the turboprop had on routes and passengers wherever the airplanes flew.

Its capacity on a par with the Convair 340 and 440, the Viscount distinguished itself with its speed and qui­eter interior noise level, while at airports its shrill whine was a familiar nuisance. Like the Capital, Northeast, and Trans-Canada turboprops, Continental’s larger, 56-seat Viscount II was all-first-class configured and advertised as “First in the West with Jet Power Flights,” operating between Chicago and Los Angeles with stops at Kansas City and/or Denver beginning May 28, 1958. Meanwhile, Club Coach DC-7Bs han­dled the Chicago-Los Angeles nonstops until Boeing 707s replaced the type in 1959. Viscount II service was later expanded to routes in Texas and across the south­western tier of states.

The Fairchild-built F-27 started flying with West Coast Airlines in September 1958, marking the world’s first revenue Friendship service. The type was an ideal candidate in the growing local-service-carrier arena, but West Coast continued to operate DC-3s in smaller mar­kets until the carrier became part of Air West in 1968.

Bonanza Air Lines began transitioning to turbo­prop service on March 25, 1959, when its first three F-27A Silver Darts began revenue flying. Barely 19 months later, the carrier retired its last DC-3 and claimed credit as America’s first all-jet-powered airline, growing the fleet to 16 airplanes.

Long, slim engine nacelles mounted on short, stubby wings was the design hallmark for Lockheed’s Electra, an airplane that was larger than the Vickers Viscounts but smaller than the Bristol Britannia. Introduced in 1959, Electras soon brought "jet-powered" airline ser­vice to smaller regional cities throughout the world. (Lockheed via Mike Machat Collection)

Close behind, San Francisco-based Pacific Air Lines began flying F-27As up and down the West Coast on May 1, eventually operating an even dozen of the turboprops. The airline began further expansion with

second-hand Martin 404s about the same time. Together, the two variants permitted phase-out of Pacific’s DC-3s, which soldiered on until 1964.

In the eastern United States, Piedmont Airlines began upgrading with F-27s on November 14, 1958, growing its new turboprop fleet to eight. As with Pacific, Piedmont acquired used Martin 404s as well. Seventeen were purchased from TWA to replace DC-3s and came on board three years after the Fairchilds.

The first of seven F-27s for Midwestern operator Ozark Air Lines rolled off the Ffagerstown, Maryland, factory assembly line July 16, 1959, and was delivered only 11 days later. But the type did not begin earning revenue for Ozark until the following January. The car­rier also flew seven Convair 240s in the early 1960s, then Martin 404s. Like most of the local-service carri­ers, Ozark continued to operate DC-3s well after the turboprops arrived and finally withdrew them for good in October 1968.

In Alaska, Northern Consolidated Airlines (NCA) and Wien Alaska F-27s transported freight and hearty passengers to small towns in the Last Frontier. NCA took advantage of the F-27B’s large cargo door to accommodate bulkier freight, while Wien operated F-27As. In Hawaii, Aloha Airlines operated the origi­nal model between Honolulu and island destinations.

Allegheny also operated F-27s but did not receive the type until the end of 1965. By then, carriers were looking to the stretched FH-227 model.

While the F-27 was ideally suited for local-service – carrier routes, the Lockheed 188 Electra became the turboprop of choice for trunk carriers, designed for short- to medium-haul segments while jets were assigned to longer legs. The Electra comfortably seated around 68 customers in four-abreast, first-class layouts plus a spacious, six-seat aft lounge.

On January 12, 1959, the first of 40 Electras began revenue service in the colors of Eastern Air Lines. These all-first-class Golden Falcon turboprops initially seated 66 and operated the carrier’s principal routes on the East Coast, spreading their wings to points as far west as San Antonio. It would be a full year before the type was superseded by Douglas DC-8-2 Is and began con­centrating on shorter routes.

American Airlines Electra Flagships would have beaten Eastern’s into service were it not for a 22-day pilot strike that began on December 19, 1958. American considered placing the type into service on transconti­nental nonstops for a short time while awaiting its first 707s, but the strike scotched that plan and revenue Electra flights began on January 23, 1959, between New York and Chicago, just two days ahead of the first 707 service. Seating capacity was 68, ideal for high-frequency service between Chicago and the East Coast, replacing DC-6 and DC-7 Flagships. The type was only sched­uled as far west as El Paso. American bought 35 Electras, with an eye toward 25 more, but instead chose additional Boeing jets.

National Airlines, the first carrier to order Electras, took 14 from the factory and later 3 from American Airlines. Configured with 54 first-class and 18 coach seats, the turboprops entered service on April 23, 1959, on the New York-to-Miami route. They became National’s workhorse across the route system until the arrival of the airline’s first DC-8s in 1960, even serving on longer flights to the West Coast when the routes were awarded to National in 1961.

Dallas-based Braniff International Airways pur­chased 10 Electras, placing its first into service on June 15, 1959, and the type quickly began appearing at most of the airline’s North American destinations. Although sold as first-class service, the 188s featured a 70-seat, alternating four – and five-abreast, arrangement.

Advertised as “a totally new dimension in jet-age travel,” Western Airlines began Electra/JET service on August 1, 1959, between the West Coast cities of Los Angeles, San Francisco, Portland, and Seattle. Two months later turboprop flights were added to Salt Lake City, Denver, and Minneapolis, as the fleet expanded to five, 66-seat, first-class-configured air­planes. Seven more Electras followed with the last delivered in 96-seat, all-coach layouts, lacking a lounge. With pure-jet service beginning a year later, the turbo­props assumed shorter segments and continued to replace Convair 240s and DC-6Bs.

Northwest was the only U. S. carrier to operate nonstop, coast-to-coast Electra flights, briefly between Seattle and New York, again while awaiting pure jets. Foregoing the aft lounge, the airline’s 188Cs were delivered in a mixed configuration featuring both Imperial first-class and Coronation coach. The first was delivered on July 19, 1959, and entered ser­vice on September 1, 1959. Medium-haul work was the norm for these 18 turboprops, which were reas­signed to even shorter routes with the delivery of more jets.

Intrastate California operator Pacific Southwest Airlines, more commonly known as PSA, found the Electra to be a perfect fit for its routes between San Diego and San Francisco, with most flights stopping at Los Angeles International or Hollywood-Burbank, where the type was built. Seating 98 passengers, including 6 in the lounge, PSA’s Electra Jets boasted a

Ф

25-minute time between San Diego and the L. A. basin, and one hour to San Francisco. With cheap fares and frequent service, PSA thrived with this rugged airplane, its first type to be purchased new. Initially, three 188Cs replaced four DC-4s, followed by three more Electras including the prototype, refurbished after taking part in the type’s certification program.

WELCOME ABOARD THE CONVAIR 990

Подпись: The 990 was the only commercial jetliner to utilize anti-shock bodies on the trailing edges of its ultra-thin wings. Added to take a continuous airflow over the upper wing surface, they lessened or delayed the shockwave that increased drag at speeds above Mach .80. The pods served as additional fuel tanks in all but the aft sections and also contained discharge nozzles for fuel jettisoning. (Jon Proctor Collection)

The differences in this airplane become apparent even before you enter the cabin, for the door is shaped unlike any other in the world. Vertically straight on the left side, but tapered-in on the right, this windowless device is a marvel to behold.

Walking down the aisle to your seat, you notice the coach cabins five-across seating configuration. As with the Convair 880, it’s two on one side and three on the other —a configuration that won’t be seen in other jetliners until the Douglas DC-9 enters service in 1965. Taking your seat just aft of the wing you look out the window and can’t help but notice the 990’s sleek and curvaceous “speed pods” mounted on the wing’s inboard trailing edge. With the engines now started and whining in unison, the ground tug pushes your airplane back from the gate, and then the magic of this machine becomes readily apparent.

The somewhat firm ride while taxiing is more reminiscent of Convair’s B-58 Hustler supersonic bomber. Like driving a Ferrari in second gear, you can’t help but sense the potential performance of this airplane. Taking the runway, the captain pushes the thrust levers to their stops and nearly 65,000 pounds of thrust from four General Electric turbo­fans sends you bounding down the concrete in what feels more like a takeoff in a jet fighter. You notice the look of surprise on the faces of your fellow pas­sengers as the 990 rotates smartly and climbs at a somewhat steeper angle than that “straight-pipe” 707 you flew on last time.

With flaps and slats retracted, the 990 now climbs swiftly to its cruising altitude. Soon the wind noise from the outside air rushing by your window at more than nine-tenths the speed of sound tells you that you’re indeed flying aboard the fastest jetliner in the skies.

WELCOME ABOARD THE CONVAIR 990
ur story ends in 1962 as intercontinental jetliners reach maturity, but commercial aviation contin­ued to develop for many years thereafter. Smaller “regional” jetliners, larger “wide-body” jetliners, and even supersonic jetliners all took to the skies by the end of that decade. Perhaps the most graphic change in the industry is evident in the number of American airliner manufacturers. Of the five companies building com­mercial airliners in the United States at the beginning of our story, only one remains in business today.

Although our story ends with the introduction of larger and more refined fanjet-powered airliners, the continued evolution of air travel in the Jet Age bears mention as a fitting and proper ending to this book. By the end of the twentieth century, the airline industry had transformed itself from a “higher, faster, farther”
mentality to a “less is more” frame of mind. The proud post-World War II generation who led the endless quest for greater speed, range, power, and passenger capacity gave way to a more modern group of industrial thinkers who toiled to bring less operating cost, less fuel consumption, and less noise and pollution to the world at large. By the turn of the century, the torch of progress had been passed to a new digital generation of airliner builders and operators, although their numbers were definitely fewer than before.

Former titans of the airline industry who were pilots themselves or “airplane people” as well as busi­nessmen, had also been replaced by a new breed of generic corporate leaders armed with MBAs and fiscal management skills that fit the newly homogenized cor­porate culture running rampant throughout the airline

world and the world at large. Indeed, the only constant in this beloved industry became change itself. On the airframe and engine manufacturing side of the ledger, a myriad of companies worldwide began merging into seemingly unidentifiable corporate conglomerates. By the mid-1960s, proud names like Martin and Convair were gone, and other once-untouchable companies like Douglas and Lockheed were suddenly pushed to the edge of financial oblivion.

Pummeled by manufacturing problems and produc­tion delays exacerbated by jet-engine deliveries being diverted for the rapidly growing war in Vietnam, the Douglas Aircraft Company merged in a “shotgun wed­ding” with military manufacturer McDonnell in April 1967. Lockheed, whose turboprop Electra effectively bridged the gap from props to jets, was kept afloat until the advent of its L-1011 Trijet, bolstered through the lean years only by the company’s successful military business. The biggest surprise, however, was that Boeing, once the undisputed underdog in the airliner manufacturing world, had now risen to the top of the pyramid by virtue of its undeniable success with the 707 series. This pioneering airplane sired an entire family of new jetliners, large and small, each one breaking barriers and establishing jet passenger service in new ways.

In October 1978, the Airline Deregulation Act was signed into law by then-U. S. President Jimmy Carter. This well-intentioned piece of legislation quickly turned the airline world on its proverbial ear. Although the noble intent was to lift restrictions on domestic routes and airfares, thus encouraging healthy competition, the result was rampant, unbridled route expansion, an explo­sion of new upstart carriers, and the end of many estab­lished airlines, all happening at unprecedented speed and on an unprecedented scale. The David-and-Goliath suc­cess story of tiny Southwest Airlines emerging as an industry giant was also written (although the carrier began operations in 1971), as it continued to thrive despite the challenges posed by Deregulation. However, there were many more tales of sordid failure as count­less new upstarts tried to emulate Southwest’s unique business model with little success.

America’s domestic trunk airlines began to stumble while trying to compete on newly acquired overseas routes purchased from struggling Pan American World Airways —the same company once proudly called “The Chosen Instrument.” By the end of the century, Pan Am, along with Braniff, Eastern, National, Western, and more than 100 regional and local airlines no longer existed, having been either merged into other carriers or plunged into bankruptcy and oblivion. TWA held on valiantly but then disappeared in 2001, with pieces of the company having been purchased by American Airlines. Today, only American, United, Continental, and Delta remain as the surviving U. S. “legacy carri­ers,” with Northwest —itself an amalgamation of older airline names —being merged into Delta as this book is being written.

In the late-1970s, a grim undercurrent also began to appear on the domestic airline scene with insidious acts of violence involving commercial aircraft. The casual inflight atmosphere of friendly visits to open cockpits and captains strolling down cabin aisles personally greeting passengers came to an end. Even airport access where a young wide-eyed kid could hang on a chain – link fence or stand on a sweeping observation deck was slowly replaced by a darker “future shock” world of beeping metal detectors, barbwire fences, and alarmed terminal doors. Back in the 1950s, a sinister wave of air­liner hijackings and inflight bombings to collect passen­gers’ life insurance swept the industry, but by the 1980s, a number of U. S. airline flight-crew members had been tragically shot inflight with the resultant loss of their airplanes and all the innocent passengers onboard.

Although violent hijackings and airliner losses from terrorist bombings had occurred overseas, the first sub­tle hint of international terrorism reaching U. S. shores appeared with a deadly bombing at New York’s LaGuardia Airport Terminal at Christmastime 1975, when members of an Eastern-European political sect hid timed explosives in a public baggage locker. By the late – 1990s, both Pan Am and Air India had lost Boeing 747s to explosive devices hidden in luggage containers with the loss of all onboard. Then, on a bright, clear September morning in 2001, the unthinkable happened as a stunned world witnessed on live television hijacked operational airliners being used as terrorist weapons for the first time in history. Three were flown into buildings and one crashed short of its intended target, but after the tragedy of September 11, the airline world —and the world in general—would never be the same again.

BOAC Comet 1: From Triumph to Tragedy

The riches-to-rags story of Britain’s de Havilland Comet 1 has been told countless times. A sleek new air­liner powered by turbojet engines is unveiled to an expectant industry in England in 1949. By the summer of 1952, this acclaimed new jetliner is in passenger service on routes throughout Europe and Africa, and a postwar world exults in wonderment at this new technological breakthrough. The joy is short-lived, however, when in January 1954, a Comet 1 disintegrates in midair after tak­ing off from Rome and plunges into the Mediterranean Sea with the loss of all passengers and crew.

Before a curious and grieving world can even understand what happened, a second Comet 1 crashes three months later also after taking off from Rome and under the same mysterious circumstances with the loss of all on board. This was the fifth crash of a Comet in its first two years of commercial operation, and now the race is on to find the technical culprit that is destroying Britain’s newest, most modern, and most celebrated air­plane. With the second inflight breakup accident comes the immediate grounding of the type, and a loss of face and confidence in Britain’s aviation supremacy. What
kind of insidious inflight occurrence caused two of the world’s most modern jet aircraft to experience catas­trophic structural failure and literally explode in midair? Was it a bomb? Was it human error? Or was it possibly a design flaw in the aircraft itself?

After complex underwater salvage operations aided by the Royal Navy recovered major portions of the air­frames from both Rome crashes, the Royal Aircraft Establishment (RAE) at Farnborough launched an investigation of never-before-seen proportions. The hunt began for the cause of the accidents with the reconstruction of actual aircraft wreckage on an arma­ture that indicated beyond any shadow of a doubt the airplane had indeed disintegrated in midair. Then an Italian fisherman’s net yielded the “smoking gun” that confirmed the solution to the mystery. A frame from one of the Comet’s square passenger windows found in the fisherman’s net showed that the fuselage had rup­tured from metal fatigue at a point near the corner of the window, extending upward to an equally rectangu­lar Automatic Direction Finder (ADF) antenna housing on the top of the fuselage. The rupture caused an explo­sive decompression of the cabin, leading to immediate catastrophic structural failure of the rest of the airframe.

In historical hindsight, this fact would seem to indi­cate that de Havilland had not tested its new airplane sufficiently, but nothing could be further from the truth. Knowing full well this airliner would be operat­ing at speeds and altitudes twice that of existing piston – powered aircraft, de Havilland engineers proceeded with fatigue testing of every minute facet of the Comet’s design and construction. With untiring effort, struc­tures were put to the test where engineers attempted to duplicate the rigors of countless aircraft “cycles,” that is the series of structural loads resulting from a takeoff, climb to altitude, descent from altitude, and landing. Exhaustive testing at Hatfield simulated an aircraft ser­vice ceiling of 40,000 feet. What couldn’t be duplicated, however, were the severe temperature differentials from sea level to 40,000 feet, and as a result of these accidents, new methods of load simulation were devised at Farnborough for use on future aircraft designs.

With a complete Comet fuselage immersed in a giant tank of water to simulate pressurization forces on the cabin at altitude, patterns now began to emerge that led to the possibility of metal fatigue in the outer skin of the fuselage. When the test cabin itself ruptured inside the water tank, the pattern of metal fatigue was conclusively established. Further study and matching of wreckage fragments from the first Comet lost revealed that the explosive decompression forces were so great that dark blue-black paint from the letter “C” in the BOAC title above the windows was found in a deep gouge on the leading edge of the right wing indicating violent span-wise or lateral impact. This clue graphically showed that the explosive force of the rupture was so great that it exceeded the forward velocity of the air­plane at that moment.

As with any aviation accident, tragedy yields infor­mation and knowledge so that a particular problem can be avoided in the future. In the case of the Comet, met­allurgy techniques, manufacturing methodology, and aircraft skin structural properties were modified to include an integral reinforcing framework built into the
skin itself much like “quilted” aluminum foil used in common households today. Additionally, the passenger windows on all British airliners built after these acci­dents were manufactured in the shape of an ovaloid to eliminate the smaller-radius corners from which the fatal fatigue cracks emanated on both Comets that dis­integrated.

Although the reputation of Britain’s commercial aviation industry was tarnished by the discovery of the design flaw that led to these accidents, de Havilland went back to the drawing board and developed improved and more advanced versions of the Comet which eventually reentered passenger service in 1958 and flew successfully well into the latter part of the twentieth century. But the story of the Comet deserves closer scrutiny than just the crash investigation, as this airplane represented the great hope and rebirth of Europe’s proud aviation industry rising from the ashes of World War II’s destruction, and was intended to show the world that England was once again a leader in aircraft design.

Evolving from design studies in 1944 for a small jet – powered mail airplane with a canard wing planform, the original de Havilland Comet was envisioned as a small high-speed, six-passenger transport powered by three turbojets buried in the aircraft’s tail section. As further marketing studies clearly indicated the need for a larger – capacity aircraft, the DH-106 emerged as the final con­figuration, featuring four 5,000-pound-thrust de Havilland Ghost turbojet engines buried inside the wing root with a slightly swept wing and conventional straight tailplanes. This new aircraft would carry 44 passengers at speeds of 490 mph on route segments of up to 1,500 miles. With its bare metal skin gleaming in the hazy summer sunshine, the formerly secret jetliner was rolled out of the factory hangar on July 27, 1949.

First flown at Hatfield later that very same day by de Havilland’s Chief Test Pilot, John Cunningham, the Comet wowed all observers although most of the crowd, including the British Press, had already gone

home thinking the flight would be scrubbed due to typically inclement British weather. As word spread of this new airplanes successful and impressive flight tri­als, the traveling public began to anticipate a sense of futurism at the thought of being able to actually fly around the world in a jet-powered commercial airliner. Such an expectation was especially pervasive consider­ing that only the Canadians had a competing design with their smaller Avro Jetliner, and that the American aviation industry didn’t even have an airplane on the drawing boards to seriously compete for the Comet’s pride of place.

Ordered initially by BOAC, the Comet 1 soon began to attract the attention of other world airlines, and tentative orders followed from Aeromaritime, Air France, Canadian Pacific, the Royal Canadian Air Force, and Britain’s Royal Air Force. With the promise of even larger and longer-range Comet versions, Pan American World Airways and Capital Airlines in the United States proudly added their names to de Havilland’s order book. By the time BOAC’s first Comet 1 entered passenger service on the London-South Africa route on May 2, 1952 (via Rome, Cairo, and points south), the airplane was firmly expected to be a world beater, bringing deluxe passen­
ger service and significantly reduced travel times to routes emanating from Europe, and eventually other continents as well.

To put the Comet’s operational service into per­spective, simply read about the other airliners flying at this same time. In 1954, Lockheed Constellations along with the Douglas DC-6 and DC-7 were the pressurized “queens of the skies” throughout the world, offering new levels of passenger comfort, speed, and range to the world’s airlines. This was especially true when com­pared to the unpressurized 200-mph Douglas DC-4s that entered service immediately following the war. With the Comet, the world had a brand-new airliner capable of more than doubling all of these operational parameters in the same time period.

By the beginning of 1954, BOAC’s Comet routes had expanded to include the Middle East, India, Singapore, and Japan. As was inevitable with any new paradigm, however, accidents began to occur that, in all fairness, could have happened with any aircraft. On October 26, 1952, a Comet was damaged after stalling on takeoff in Rome. On March 2, 1953, another Comet was destroyed while taking off from Karachi, and then on May 2, 1953, a third Comet was lost in a raging thunderstorm near Calcutta. These accidents did not go

unnoticed, but when Comet G-ALYP mysteriously fell from the sky near Alba, Italy, on January 10, 1954, the world took special notice. BOAC temporarily grounded all of its Comets until it was determined that what had occurred was strictly a one-time happenstance, and the type was returned to service on March 23. Then, only two weeks later on April 8, Comet G-ALYY repeated the Alba tragedy, and the Comet Is brief but supreme reign was over.

R

eliable coast-to-coast nonstop flights could, the­oretically, have begun with the introduction of DC-4s and Constellations following the end of World War II. In fact, TWA operated one “scheduled” Los Angeles to New York nonstop on February 3, 1948, when a fierce winter storm covered the Midwest. Flight 12’s regular Kansas City and Chicago stops were canceled and the Model 049 Connie covered the 2,470-mile flight in 6 hours 55 minutes.

While air travel began its rapid growth during this time period, the number of transcontinental tick­ets probably did not justify such flights. Although the market was sufficient by the early 1950s, and aircraft could stretch their legs across the country nonstop, they did not. Why?

In his book, Howard Hughes and TWA, Robert W. Rummel wrote that the airline’s traffic managers argued against the longer flights, based on their
belief that passengers wanted an en-route stop to get out and stretch their legs, and that no one wanted to fly nonstop across North America for up to nine hours. Perhaps a more important reason was that pilot contracts and U. S. federal air regulations pro­hibited flights of more than eight hours without an augmented crew, which would also result in addi­tional costs to the airline. TWA operated its transat­lantic flights this way as a matter of expediency, but not on long domestic routes where crew changes could be easily carried out.

When American Airlines announced plans to begin coast-to-coast nonstop service with its new DC-7s, TWA quickly inaugurated its own nonstop service and upstaged the competition. On October 19,1953, “Ambassador” Flight 2, an overnight service from Los Angeles to New York-Idlewild, operated with the Model 1049 Super Constellation, which could barely cover the distance in less than eight hours; it was scheduled for 7 hours 55 minutes. Prevailing winds would not permit a westbound flight within the time constraint, so a 15-minute stop was made at Chicago for a crew change with no local traffic allowed!

Not to be upstaged, American Airlines quickly retaliated with DC-7 “Nonstop Mercury” flights in both directions, on November 29. Although the Douglas was faster than the Super Connie, and flew an eastbound 7-hour 15-minute schedule, it could not
reliably operate its under-eight-hour westbound time frame, a fact quickly pointed out by American’s pilot union but quietly ignored by federal officials. More than a dozen modifications were carried out in an effort to squeeze extra speed from the DC-7’s R-3350 engines, but this was not enough to resolve the dilemma.

Then, early in 1954, government restrictions were lifted to make transcontinental nonstops in excess of eight hours “legal,” and American revised its west­bound schedule to 8 hours 15 minutes. While TWA and its pilots reached agreement on overtime for duty in excess of eight hours and began nonstops in both directions, American and its crews deadlocked over the work rules. The entire pilot workforce walked out on July 31, 1954.

The company’s legendary president, C. R. Smith, on military leave at the time, returned infuriated about the work stoppage. He quickly reached an agreement with the pilots that called for extra pay on flights —on DC-7s only—exceeding eight hours, end­ing a 24-day strike. TWA retained a bit of an advan­tage with eight sleeping berths available on its Super Connies, unlike the DC-7’s standard “day plane” configurations, but both carriers offered lounges and lavish meal service. United Air Lines, which received its first DC-7s six months behind American Airlines, launched nonstops from San Francisco to New York —again eastbound only —on June 1, 1954; west­bound flights began nearly a year later.

San Francisco and Honolulu. Its furnishings included provisions for 28 upper – and lower-bunk berths. In a day configuration, the airplane could accommodate up to 103 passengers, and featured a unique 14-passenger lounge located below the main cabin. Only 56 Stratocruisers were built, for Pan Am (21, including the prototype), Northwest (10), American Overseas (8), BOAC (10), and United (7). Northwest was the last of the original customers to withdraw the type, on September 15, 1960.

Unlike surplus DC-3s and DC-4s, used Stratocruisers were difficult to place with second-tier operators. Knowing this, the type’s original owners traded them in to aircraft manufacturers as down pay­ments on jet equipment. Transocean Air Lines, then the largest non-scheduled airline, bought 14 Stratocruisers that Boeing acquired in this fashion. Barely two years later, the airline went bankrupt and its Strats were sold
at auction with only four in flyable condition. A few other short-lived attempts were made to utilize second­hand examples, but did not succeed.

The only long-term success realized with second­hand Stratocruisers came in the form of Aero Spacelines’ radical modification to the airframe that resulted in the “Pregnant Guppy,” with an enlarged fuselage capable of ferrying oversize cargo. On the mil­itary side, the Israeli Air Force picked up five ex-Pan Am 377s for use as freighters, two of which were con­verted to swing-tail configurations.

Although Boeing could not claim great success from its civil Stratocruiser version, it prospered from the construction of 888 C-97/KC-97 military variants. But Stratocruiser production was important in allowing the manufacturer to keep its hand in the civilian airliner market, which it would begin dominating in the 1960s, with its revolutionary turbojet 707 series.

Boeing, primarily a builder of bombers and transports, designs a brand-new prototype that will change the heady game of airliner manufacturing forever. Developed to become a high-speed tanker for the Air Forces emerg­

ing fleet of new jet aircraft, this four-engine transport becomes an obvious candidate for airline service as well. The public begins to embrace the concept of air travel by jet, and the revolutionary Boeing 707 is born.

ost first-time travelers aboard the Electra were, like the airlines, transitioning from aircraft such as the DC-6 and Constellation plus, to an extent, Convair and Martin twins. With the Electra’s self – contained boarding stairs forward of the wing, one had a chance to get up close and personal with the air­plane before even stepping aboard. Compared to the older piston-powered airliners, the Electra looked big, in part because it sat higher off the ground. Its larger passenger windows and fatter fuselage were noticeable, but what really impressed me upon step­ping toward the air stairs were the engines and abso­lutely huge propellers, which reeked of power even while resting at the gate.

Stepping into the airplane, I was impressed with the softer, indirect lighting and a cabin design that gave it a roomy appearance. Soft background music added to the contrast between old and new. Designed for short – to medium-haul routes, most Electras featured carry-on luggage compartments near the forward door. It was almost like boarding a Convair-Liner, yet as I looked aft, the rear lounge mimicked a DC-6 or DC-7, as did the galley adjacent to the second door behind the wings, where I was used to boarding a Douglas.

My first Electra flight was on Pacific Southwest Airlines (PSA), from San Diego to Los Angeles in December 1959, only two months after the type entered service along the California coast. Even in its
98-seat, all-coach layout, it felt roomy, probably enhanced by the six-seat lounge one would not expect to see when riding on a $5.45 ticket.

I chose to sit in the last row of the forward cabin, just ahead of the prop line, so I could see those mighty Allisons fire up. From my window seat, I watched as the props blended into what looked like two giant saucers. Expecting a higher noise level as we pulled away from the gate, I was surprised to feel the brakes release and no increase in propeller rotation, only a slight engine-pitch adjustment. Welcome to the world of constant-speed propellers.

After a short taxi to Runway 27, and no pause to run up engines, the propeller pitch changed again and I was pushed back into my seat as the Electra acceler­ated rapidly. Unlike the longer takeoff roll I was used to, this bird literally jumped into the air and climbed through the marine cloud layer at a steep angle, burst­ing into bright sunlight.

PSA kept the cockpit door open in flight (those were the days!), with a red cloth rope across the open­ing, giving passengers a peek at the front office. Although the flight engineers seat partially blocked the view, one could see the wide work area that required separate throttle quadrants for the captain and co-pilot.

Although this first flight was smooth, I later found that the Electra s relatively stiff, stubby wings made it more susceptible to turbulence. Its cabin noise level close to the engines was higher, much like the propliners it replaced, but even attached to the

propeller, the turboprop engines featured much lower vibration levels, adding to overall passenger comfort.

My PSA flight touched down at Los Angeles International barely 20 minutes after liftoff from San Diego. A propeller-pitch change brought the Electra
to a quick stop on the runway, followed by a short taxi to the terminal on Avion Drive. The use of both doors allowed a less-than-10-minute turnaround, yet another Electra feature that made it attractive to air­lines, and an ideal fit for PSA.

Here is another example of a prop-era color scheme being applied to a new jetliner still years away from rolling out through the factory doors. Eastern’s classic "meatball" scheme, as it was popularly referred to, is applied to a DC-8 in this artist’s rendering, and doesn’t look all that bad. The large underwing lettering might not have been very effective when the jet was cruising at 35,000 feet. (Mike Machat Collection)

Factory brochure prepared for customer airlines by Boeing details the technical aspects of the new 707, although the jet’s final color scheme had not yet been defined. Here we see a DC-7-style paint job as it would have looked on the 707, but American’s first airplane was still several years away from reality when this book­let was prepared. It is interesting to note that American was the only U. S. airline to have the engine nacelles painted to match the fuselage markings. (Craig Kodera Collection)

Another clean and classic Raymond Loewy color scheme was developed for application to United’s new Douglas DC-8s and Boeing 720s. Nicely complementing American’s bare-metal-with-orange-striping motif and TWA’s striking red arrowhead design, the red, white, and blue of United’s new look was worn on its vast fleet of jets all the way into the mid-1970s.

Smaller Jetliners in the mid-1960s

While the brilliant French Sud Caravelle became the Western world’s first short – to medium-range jet­liner in the late-1950s, a new flock of twinjet and tri-jet airplanes emerged in the following decade bringing sig­nificant advances in airframe, powerplant, and systems technology. In 1962 Britain’s Hawker Siddeley Trident became the first new smaller jetliner to take flight after the original Caravelle, but it was another three-engine design from Seattle that truly launched medium-range jet-powered service two years later. Boeing’s 727 was a revolutionary airplane when first flown, bringing jet speed, comfort, and convenience to smaller regional air­ports previously served by DC-6s, Constellations, and even Convair-Liners. With a total of more than 1,800 built in two basic models and operated by major carri­ers all over the world, the 727 was the most successful

airliner ever flown at the time, becoming the undisputed DC-3 of the Jet Age.

After a failed marriage between Sud and Douglas to market the Caravelle in the United States, Douglas developed its own twinjet airliner called the DC-9, which entered service in 1965. Starting as a 100-seater known as DC-9-10, the basic design grew in typical Douglas fashion all the way to the Series 50. The next step was a rather big one, when the latest iteration became the DC-9 Super 80 with larger engines, wings, tail, landing gear, and a stretched fuselage that held up to 165 passengers. The most advanced airliner of its time, the Super 80 was renamed the MD-80 (MD stand­ing for McDonnell Douglas, replacing the classic DC, or “Douglas Commercial” designation) and grew into the MD-90, and the shorter-fuselage MD-87. The final member of the family was originally called the MD-95, a name that morphed into the Boeing 717 when that company acquired McDonnell Douglas in 1997.

Meanwhile, in England, the newly established British Aircraft Corporation (ВАС) designed a small twinjet for inter-European routes that eventually became a DC-9 competitor. Called the ВАС 111, it entered service in 1965. Ironically, this airplane was flown in the United States, as well, by American, Braniff, and Mohawk to connect those carriers’ smaller cities to their 707 and DC-8 trunk routes.

By 1968, Boeing was building a shorter, twin – engine feeder liner of its own called the 737, launched by Lufthansa and first operated in the United States by United Air Lines, ironically replacing aging Caravelles on United’s routes. In a classic example of how dramat-

Smaller Jetliners in the mid-1960s

Bringing jet service to the world’s smaller cities was the Boeing 727, which entered service in 1963. With more than 1,800 built, the 727 was to the Jet Age what the Douglas DC-3 was to the late-1930s—a machine that could make a profit for companies flying passengers to destinations all over the world. Many are still flying today. (Boeing/Jon Proctor Collection)

ically things can change in the airline industry, the mod­est and stubby little 737 grew in size, power, range, and passenger capacity over the years, and is now flying in its third design makeover, glass cockpit and all. With more than 6,000 delivered (and another 2,000 currently on order), the 737 has become the most successful single­aisle jetliner in history. To put all this in proper per­spective, the latest version in the 737 series can carry more passengers over longer distances on two fewer engines and with two fewer flight crew than Boeing’s original 707 could when first introduced in 1958!

Aircraft of the Era

Progress in aeronautics is nothing if not fast. Starting in the mid-1930s, commercial aircraft design took a huge leap skyward with the first DC-2 and DC-3, which at the time were termed the “Giant Douglas Flagships” by American Airlines. These twin-engine airliners were soon eclipsed by the four-engine Douglas DC-4E and Boeing 307, followed by the pro­duction DC-4 and Lockheed Constellation, with the Douglas DC-6 being considered the thoroughbred of that era. This significant march forward spanned a total of only 12 years, and took us from airplanes carrying 21 passengers in sometimes grueling unpressurized multi­stop transcontinental service, all the way to luxurious skyliners carrying 50 passengers in pressurized comfort spanning the great oceans, and doing so at about twice the speed of the fastest aircraft a decade earlier. Even at the intercity level, the modern new “twins” from Convair and Martin enjoyed the same speed and habit­able higher-altitude cabins as the larger aircraft. We see that the world of postwar commercial aviation enjoyed a quantum improvement from its pioneering forebears of the Depression era.

Lockheed Constellation 049 through 149

It is easy to lose sight of the fact that what started in 1936, as the modest 36-passenger Excalibur airliner from Lockheed, became the 049 Constellation only three years later, which was an airplane with a pressur­ized cabin capable of carrying 46 passengers over a dis­tance of 3,500 miles. At TWA’s behest for nine orders, Lockheed commenced with the airplane, making it the company’s largest undertaking to date. Pan American ordered 40 of the transoceanic type 149 (decreased in 1945 due to an order for the Boeing Stratocruiser). The prototype Constellation made its first flight on January 9, 1943, smack in the middle of the war. The airplane wore standard olive-drab-and-gray USAAF camou­flage and insignia. This date highlights the reason that the very advanced Constellation became available to the airlines so soon after the war. The first Constellations were actually Army Air Force C-69 transports, and prior to the war’s end, Lockheed manufactured 31 of these airframes making them available to the airlines at incredibly low prices.

High speed for the Constellation was derived from its powerful Curtiss-Wright R-3350 Duplex Cyclone engines, which gave the aircraft a 25-percent boost in power versus the Douglas DC-4. The “Connie,” as the flying public knew it, also offered greater range, faster speed, higher payload capability, and a commensurate lowering of cost-per-seat-mile [the cost of moving one passenger seat over a distance of one mile] some 23 percent below the Douglas air­liner. (Note: This book chronicles the ongoing and ever-present crosstown rivalry and “back and forth” success between the designs of Lockheed and Douglas during the 1940s and 1950s. There always seemed to

be a competition for orders between these two Southern California airliner giants.) The 049 was also the first production transport to have hydraulically boosted controls.

Pan American began the first scheduled transat­lantic service via the Constellation on January 20, 1946, from New York to Lisbon, while the first transconti­nental service came from TWA on February 15, 1946. TWA offered one-stop service between Los Angeles and New York for a scheduled time of 9 hours 45 min­utes. This was in stark contrast to United’s and American’s unpressurized DC-4s that made two stops while crossing the United States. This advantage made TWA the leader in postwar transcontinental service, although that would dissipate one year later as the DC-6 began its work at American and United.

The 367-80: Boeing’s $15 Million Gamble

Подпись:

First, as previously noted, the de Havilland Comet entered service in May 1952, but was subsequently grounded within two years, after its infamous series of accidents. Second, Boeing froze the design for its new “prototype jet transport” into a sleeker configuration with four jet engines, each in their own separate under­wing nacelle, a stubbier vertical fin, and a more airliner­like cockpit design. Disguised with a deceptive “Model 367” designation (used internally by the company for its KC-97 military tanker/transport version of the Stratocruiser), this larger, faster, and more powerful design was the eightieth configuration considered. Hence, the official name for Boeing’s new jet prototype became the 367-80.

Constructed in a special walled-off and highly secure area of Boeing’s historic Renton, Washington, facility, the “Dash 80” was built in only 18 months, and was rolled out for Boeing employees and industry representatives
on May 15, 1954. This one-of-a-kind proof of concept demonstrator was unlike any other airplane ever seen at that time. Painted in a striking school-bus-yellow and chocolate-brown color scheme, the jet was 128 feet long with a 130-foot wingspan and a tail height of 38 feet. The engines were Pratt & Whitney’s new J57 turbojets, and the airplane’s main landing gear sported four wheels on each side instead of the traditional two. Anyone who saw the Dash 80 knew it was something special. What they didn’t know was that this airplane would change air travel forever by siring an entire family of jet transports that would reduce travel times between any two places on earth by a staggering 50 percent.

Christened by Mrs. William Boeing as the “airplane of tomorrow,” the 367-80 soon underwent preparation for its first flight. After a series of rigorous systems checks and taxi tests, the giant craft lifted off from Renton’s runway for the first time on July 15, 1954,

piloted by Boeings Chief Test Pilot, A. M. “Tex” Johnston. The unique thing about that first flight is that there had been no airline orders placed for the airplane whatsoever. Not one! Then, as the new prototype began to demonstrate what a large jet-powered trans­port could do, the world began to take notice. So did the United States Air Force, which was in dire need of a faster aerial-refueling aircraft to service its new fleet of jet-powered strategic bombers and tactical fighters just then entering the inventory.

Boeing quickly “put its money where its mouth was” by flying the Dash 80 on a series of impressive demonstration flights, taking any number of special industry guests and aviation luminaries for their first rides in a jet-powered aircraft. Names like USAF Chief of Staff, General Curtis LeMay soon graced the passen­ger roster as he evaluated the airplane for its impending role as the Air Force’s new “flying gas station,” to be known as the КС-135 Stratotanker. Excitement was building around the new jet, as the publics anticipation of flying in America’s first jet airliner grew in magni­tude. The Dash 80 was catapulted to national attention when Tex Johnston performed not one, but two barrel rolls while flying over the famed Gold Cup speed-boat races at Seattle’s Sea Fair in August 1955. Asked later by Bill Boeing why he did it, Johnston replied in his typi­cal droll manner, “I was selling airplanes.”

On one memorable demonstration flight, Johnston was told by the Boeing Field tower to remain in posi­tion on the ramp with engines running. It was a typical rainy spring day in Seattle, and Tex noticed a company car racing out to the airplane. Emerging from the back seat was a tall, slim figure clutching his raincoat tightly to his body. Rushing up the boarding stairs, the gentle­man walked into the cockpit and unceremoniously took his place in the airplane’s jump seat. Tex turned around to greet him, and shook hands with none other than Charles A. Lindbergh, acting in an advisory capacity for Pan American World Airways. According to Johnston, Lindbergh later sat in the co-pilot’s seat and even took the controls of the Dash 80 while flying over Portland, Oregon, at 600 mph. Johnston marveled at how much aviation progress had been made in the less- than-thirty-year time span since Lindbergh’s epic solo transatlantic flight in 1927!

On October 16, 1955, with William Boeing and other VIP guests on board, Johnston flew the Dash 80 from Boeing Field in Seattle to Washington D. C., reaching a top speed of 620 mph and arriving at Andrews Air Force Base in only 3 hours 48 minutes. The fact that this flight established a new U. S. coast-to – coast cross-country record did not go unnoticed by the world’s airlines, and orders for a slightly larger produc­tion version of the new jet, called the 707, started com­ing in to Boeing in impressive numbers.

Boeing’s first airline order was from Pan American when its President, Juan Trippe, ordered 20 of the new jets. American’s C. R. Smith ordered 30, and then came Continental and Braniff orders. Surprisingly, the first foreign air carrier to order the 707 was Belgium’s Sabena, followed by Air France. Bringing up the rear in this initial batch was TWA with its pivotal order for 8 of the new jetliners, bringing the total 707 order book to 81 airplanes. Although this will be covered in more detail later, it should be mentioned that by this time, rival manufacturer Douglas Aircraft, still king of the airliner builders, had recorded 124 orders for its similar­looking, but yet-to-be-flown DC-8 Jetliner.

For awhile, it appeared that Boeing would never be able to break the decades-old stigma of being in Douglas’s shadow as an airliner builder, but when BOAC, Lufthansa, El Al, and Air India lined up to order longer-range versions of the 707, Boeing’s tally grew to 145 before the DC-8 ever flew, and the race was on. As we will see later, both of these jetliners evolved into larger and more improved airplanes, but once Boeing gained the advantage and pulled ahead of Douglas, there was no turning back. With its Dash 80, Boeing literally “bet the company” that this revolutionary new aircraft would eventually become a commercial success, and it will be considered for all of history to be one gutsy $15 million gamble that paid off quite handsomely.

 

mercial jet travel would be like for the privileged pas­sengers who would someday fly aboard a later produc­tion version of the airplane.

As with any radical new design, countless engi­neering studies resulting in numerous aircraft concepts are winnowed down to a smaller number of final con­figurations from which the actual prototype design is chosen. Emerging from this design process in October 1950 was the Boeing Model 473, an airliner featuring a double-lobed and truncated Stratocruiser-type fuse­lage. Swept and tapered vertical and horizontal stabi­lizers from the B-47 were mounted on the rear fuselage, while double-podded engines were slung from its swept wing at mid-span, one pod per side. Similar in size to the largest DC-7s and Constellations of the time, this distinctive new design looked arrest­ing to the casual viewer but somehow appeared “not quite ready for prime time.”

Conceived from the outset as more of a marketing study than an actual “hard” design concept, the 473 was to have a gross weight of 135,000 pounds and a cruising speed of 500 mph at 40,000 feet. This was unheard-of performance for its day, especially with Britain’s Comet still two years away from entering passenger service. Cargo capacity of the 473 was to be 5,000 pounds distributed in two separate lower-fuselage baggage compartments, one fore and one aft of the wing. Powerplants were to be four unspecified turbojets in the 9,500-pound-thrust category, and with its military – type drag chute, the airplane was intended to be able to operate from existing runways at any major airport in the world.

By 1954, however, two major developments had a profound effect on the future of commercial air travel.

 

This airplane’s shape didn’t just suggest the Jet Age, it was the Jet Age. With design features such as a rakish 35-degree swept wing and podded turbojets lifted directly from Boeing’s new B-47 strategic bomber, the Model 367-80 prototype, or “Dash 80” as it came to be known in industry circles, epitomized jet travel, and left Britain’s formerly cutting-edge de Havilland Comet in the dust. Cruising high in the stratosphere at almost transonic speed, the Dash 80 symbolized what com-

Impending Introduction of the Jets

Even though the first turboprops were entering service and using existing airports without any major problems, airline and airport planners wisely realized that the next generation of pure-jet airliners would require a host of new and improved airport features to
safely and effectively accommodate their operations. In addition to the obvious need for longer runways and safety overrun areas, the larger jetliners would require more ramp space for turning and parking, plus wider taxiways and runways to keep their outboard nacelles from hanging out over adjacent grass areas full of potentially engine-damaging debris.

Impending Introduction of the Jets

Newly designed airport infrastructure was also planned with novel features such as blast fences to keep ramp vehicles from being blown over by jet exhaust. Fully enclosed moveable “jet bridges” designed to shield passengers from the weather would be attached directly to terminal buildings, completely eliminating the need for passengers to be exposed to the elements. After all, it was rather hard to sell luxurious jet service when passengers were being drenched while walking

from the gate across a rain-soaked red carpet and up slippery metal boarding stairs to the airplane.

In anticipation of serving both the aircraft and passengers of the Jet Age, airline terminals themselves moved upscale. Large two – and even three-story com­plexes with floor-to-ceiling dark-tinted plate glass windows and arched or cantilevered roof structures were designed to replace simpler terminal buildings with their cinder-block walls, chain-link fences, and

Quonset-hut extensions. In most cases, this new modern look was referred to by the marketing forces of the day as being the “Airport of Tomorrow” to foster even more excitement at the thought of futuristic air travel by jet.

American Airlines’ new terminal facade at New York’s Idlewild Airport was the largest single-frame mosaic ever con­structed when it was finished in 1960. This structure, along with other inde­pendently constructed terminals for Eastern, United, Pan Am, and TWA comprised the "terminal city" concept at Idlewild. The terminal also featured separate upper and lower entrance roadways for departures and arrivals, respectively. (Mike Machat Collection)

Larger Jetliners in the late-1960s

Although public perception is that the Boeing 747 was the first airplane called a Jumbo Jet, that distinction technically goes to the McDonnell Douglas Super-60 family of advanced DC-8 jetliners. Douglas engineers at Long Beach created the world’s first 250-passenger air­liner by adding more than 37 feet to the original DC-8 fuselage, and then developing three versions of this new larger airplane by combining different engine, engine pylon, and wingtip designs to meet various airline requirements.

The first stretched model, the DC-8-61, simply added a longer fuselage to the existing DC-8-55 wing and engines. The DC-8-63 became the “Cadillac of DC-8s” by combining the -61 fuselage with a longer wing, new “flow-through” nacelles for its uprated fan – jet engines, and sleeker “cut-back” pylons for improved aerodynamics and drag reduction. By shortening the new longer fuselage and utilizing the Series 63 wing and engine configuration, the DC-8-62 was born, offering such ultra-long-range routes as New York to Hawaii nonstop for the very first time. Flown by United, Delta, Eastern, and National, plus Braniff, Air Canada, and a host of international carriers, the DC-8 Super-60 series brought a new paradigm of lower seat-mile economics to airline operators and passengers alike, setting the stage for the next big step in airliner development.

Responding to a U. S. Air Force request to develop a new giant jet airlifter, Boeing, Lockheed, and Douglas pushed the envelope of aircraft construction to new heights with the CX-HLS Program. General Electric and Pratt & Whitney did likewise for powerplant devel­opment. Standing for “Cargo Experimental, Heavy Logistics Support,” this new mammoth aircraft was to be able to carry outsize loads on its main cargo deck, with accommodations for up to 90 passengers or relief crewmembers in compartments housed in an upper deck. A new generation of high-bypass turbofans would provide a then-staggering 25,000 pounds of thrust each to lift this beast into the air.

Although Lockheed won the CX-HLS contract with its C-5 Galaxy powered by General Electric

Larger Jetliners in the late-1960s

Ushering in the era of affordable air transportation for the masses, Boeing’s 747 entered service in 1970. The dream of Pan American’s Chairman, Juan Trippe, Pan Am and Boeing once again led the way to the next paradigm in commercial jet airliners, just as they did 12 years earlier with the Boeing 707. (Jon Proctor)

engines, all five companies involved managed to parlay their newly acquired design expertise into the creation of giant new engines and airframes suitable for com­mercial passenger use.

First off the mark was Boeing with its impressive new 747 designed to the specifications of launch cus­tomer Pan American. More than 230 feet long and with a wingspan of 196 feet, this four-engine Goliath carried up to 400 passengers in mixed-class configuration with an exclusive upper-deck lounge located above the for­ward fuselage, accessible via a regal-looking spiral stair­case. Entering passenger service in 1970, the 747 went through the inevitable teething problems for integrating so large an airplane into the existing air-travel infras­tructure. It emerged, however, as a highly successful air­liner that provided affordable air travel to the masses and drove the basic cost of flying down to unheard-of levels. With more than 1,400 produced to date, the 747 soldiers on as the pioneering design that helped create the new age of affordable international air travel we somewhat take for granted today.

McDonnell Douglas entered the commercial jumbo-jet sweepstakes by complementing rather than competing with the 747. Responding to the needs of American and United for a widebody jet that could operate out of smaller airports like New York’s LaGuardia, yet still carry 275 passengers on medium – to long-range stage lengths, McDonnell Douglas came up with a three-engine design called the DC-10. The new jetliner proved to be popular with the traveling public, but suffered a series of design-related accidents that tarnished the proud Douglas name. The DC-10 also became the Air Force’s newest tanker named the KC-10 Extender, of which 60 were built, in addition to the 446 commercial DC-lOs produced in Long Beach. Production ended with a follow-on design, a stretched, re-engined, glass-cockpit-equipped jetliner called the MD-11.

Last, but certainly not least in this trio of airliner titans was the Lockheed L-1 Oil. The only jumbo jet to officially have a name, the L-1011 carried on Lockheed’s stellar theme with the clever moniker TriStar. Considered a more advanced aircraft than the DC-10 from a systems standpoint, the TriStar was capa­ble of Category III instrument landings and featured a center engine mounted in the aft fuselage fed by a streamlined S-duct air inlet. The L-1011 was ordered by TWA, Delta, Eastern, and Air Canada when McDonnell Douglas’ senior management refused to negotiate the price of its DC-10 for these same airlines. In so doing, McDonnell opened the door to intense competition from its cross-town rival. However, only 250 L-101 Is were built, and they were the last commer­cial aircraft produced by what is now the Lockheed Martin Company.
