GROUNDED

By the middle of 1963, shortly after Faith 7, Shepard’s chances of commanding the first Gemini looked bright. Then his career and health, figuratively and literally, started spinning. Years earlier, just after being selected as one of the Mercury Seven, he had complained about feeling light-headed during a game of golf; every time he attempted to swing the club, he felt that he was about to fall over. It was an isolated, peculiar incident, which did not resurface again until the summer of 1963. It came with a vengeance, usually striking him in the mornings and taking the form of a loud metallic ringing in his ears, coupled with feelings of intense dizziness and nausea. At first, Shepard dealt with the problem himself: he saw a private physician, who prescribed diuretics and vitamins such as niacin, which had little effect. It did not stop Slayton from assigning him to command Gemini 3 and, indeed, Shepard and Stafford completed the first six weeks of their training, visiting McDonnell’s St Louis plant in Missouri to watch their spacecraft being built.

He told no one in the astronaut corps of the problem. However, very soon, it became impossible to conceal. An episode of dizziness whilst delivering a lecture in Houston forced him to admit his concerns to Slayton, who sent him to the astronauts’ physician, Chuck Berry, for tests. In May 1963, unknown to everyone else in the corps, Shepard was temporarily grounded. The diagnosis was that fluids were regularly building up in the semicircular canals of his inner ear, affecting his sense of balance and causing vertigo, nausea, hearing loss and intense aural ringing. Although the incidents were intermittent, they proved sufficiently unpredictable and severe to render him ineligible to fly Gemini 3.

Known as Meniere’s Disease, the ailment was a recognised but somewhat vague condition. Indeed, formal criteria to define it would not be established by the American Academy of Otolaryngology-Head and Neck Surgery until 1972. The academy’s criteria would describe exactly the conditions suffered by Shepard:

fluctuating, progressive deafness – he would be virtually deaf in one ear by 1968 – together with episodic spells of vertigo, tinnitus and periodic swings of remission and exacerbation. Nowadays, it can be treated through vestibular training, stress reduction, hearing aids, low-sodium diets and medication for the nausea, vertigo and inner-ear pressure: such as antihistamines, anticholinergics, steroids and diuretics. In mid-1963, however, the physicians who examined Shepard had next to no idea what caused it, some speculating that it was a ‘psychosomatic’ affliction. Moreover, there was no cure.

His removal from flight status was temporarily revoked in August, with the prescription of diuretics and pills to increase blood circulation, in the 20 per cent hope that the condition would clear up on its own. This allowed Shepard to be internally assigned to Gemini 3, but when the early diagnosis was confirmed and no sign of improvement was forthcoming, he was formally grounded in October, after only six weeks of training with Stafford. During those weeks, the men had spent some time in the Gemini simulator, but little more. Not only was Shepard barred from spaceflight, but, like Deke Slayton, he also could not fly NASA jets unless accompanied by another pilot. Subsequent examinations revealed that he also suffered from mild glaucoma – a symptom of chronic hyperactivity – and a small lump was discovered on his thyroid. It was surgically removed in January 1964 and, the press announced, ‘‘would have no impact on his status in the space programme’’. In reality, Shepard had been effectively grounded for months by that point.

Ironically, at the same time, John Glenn, who had resigned from NASA after being told that his chances of flying again were slim, suffered damage to his own vestibular system. Glenn’s friendship with Attorney-General Bobby Kennedy had led to the first inkling of a political career and, after leaving the astronaut corps in January 1964, he announced his candidacy to run for the Senate in his home state of Ohio. A few weeks later, he slipped and cracked his head on the bathtub in his apartment, resulting in mild concussion and, more seriously, swelling in his inner ear, which produced similar symptoms to Meniere’s Disease. Glenn spent several weeks in a San Antonio hospital, virtually immobile, and was forced to withdraw from the Senate race in March.

Elsewhere, at the Rice Hotel in downtown Houston, Shepard pulled Stafford aside one evening that same March and asked him if Slayton had mentioned anything about the Gemini 3 assignment. No, Stafford replied, and could only listen open-mouthed as his former crewmate told him about the dizziness, the vertigo, the Meniere’s diagnosis. . . and the bombshell that Shepard was grounded. In his autobiography, Stafford recalled fearing for his own place on Gemini 3, and, indeed, in mid-April, the crew changes were announced. Slayton moved Gus Grissom up from the command slot on Gemini V to lead Shepard’s old mission and replaced him with Gordo Cooper, who had established himself as capable of enduring a long – duration flight on Faith 7. Unluckily for Stafford, however, Slayton felt that John Young was a better personality match with Grissom and designated him as Gemini 3’s new pilot. He had nothing against Stafford, of course, simply revealing in his autobiography that ‘‘Tom was probably our strongest guy in rendezvous, so it made sense to point him at [Gemini VI], the first rendezvous mission’’.

Stafford learned of his removal from the Gemini 3 prime crew from one of the flight surgeons, Duane Ross, who told him that he was now on Gus Grissom’s backup team, paired with Wally Schirra. Grissom’s original pilot, Frank Borman, would be “held for later’’ and another mission. In his biography of Grissom, Ray Boomhower cited fellow astronaut Gene Cernan as remarking that Grissom’s and Borman’s egos – both of them were strong-headed leaders – were too large to fit one mission. Indeed, in an April 1999 oral history for NASA, Borman hinted that he “went over to [Grissom’s] house to talk to him about it … and after that I was scrubbed from the flight’’. Borman, eventually, would command his own Gemini. Meanwhile, on 13 April 1964, the four-man unit for Gemini 3 set to work. Only days earlier, the first unmanned test to assess the compatibility of the spacecraft and its launch vehicle had proven a remarkable success. It came after almost three years of technical and managerial difficulties and a development programme laced with problems.
