‘Who Was In NASA 901?’: Remembering Project Gemini’s Worst Day, 55 Years On

Assigned in November 1965, the Gemini IX crew of Elliot See (left) and Charlie Bassett were tasked with flying a three-day mission in the late spring of 1966.

At 7:41 a.m. CST on 28 February 1966—55 years ago on Sunday—a pair of sleek T-38 Talon jets took off from Ellington Field, not far from the Manned Spacecraft Center (MSC) in Houston, Texas, bound for Lambert Field in St. Louis, Miss. Aboard the lead jet, tailnumbered “NASA 901”, were astronauts Elliot See and Charlie Bassett, prime crew for the forthcoming Gemini IX mission, targeted to launch in May of that year.

And following them in the second T-38, tailnumbered “NASA 907”, were their backups, Tom Stafford and Gene Cernan. Flight rules forbade a member of a prime crew to fly with his counterpart on the backup crew, lest an accident wipe out the entire specialty for one seat on the mission. Tragically, those rules held firm on the fateful morning of 28 February 1966.

Thirty-eight-year-old civilian test pilot See and 34-year-old Air Force major Bassett had been named to Gemini IX in November 1965. Their flight would last up to three days and would feature rendezvous and docking in orbit with an unpiloted Gemini-Agena Target Vehicle (GATV) and a lengthy spacewalk by Bassett to evaluate the Astronaut Maneuvering Unit (AMU).

Over the last several months, See had flown 25 times and Bassett seven times to St. Louis, in order to visit McDonnell Aircraft Corp., where Gemini IX was being built and tested. It was a 90-minute flight and on 28 February 1966 the men and their backups were headed there for two weeks of rendezvous training in the Gemini simulator. It would also afford them a chance to see the spacecraft that they would soon fly.

Sadly, the flight would end with the deaths of See and Bassett and would come within a hair’s breadth of destroying Gemini IX itself.

The days leading up to the fateful day had been uneventful. On the 27th, See and his family attended a religious service in downtown Houston, followed by the Livestock Show and Rodeo in the Astrodome. Bassett had accompanied them to the rodeo. Early the next morning, the two men arose, with See breakfasting on cereal, juice and toast and Bassett taking a run, then enjoying his own hot breakfast and coffee. Then the pair headed for the Ellington flight line. They filed their flight plans and loaded the baggage for both themselves and Stafford and Cernan into NASA 901.

Following takeoff, the two aircraft quickly reached a cruising altitude of 41,000 feet (12,500 meters) and traveled in formation. “As Stafford eased up into position on See’s wing, he and Cernan could easily make out the other two pilots with their white helmets,” wrote space historians Colin Burgess, Kate Doolan and Bert Vis in their book Fallen Astronauts.

Forty minutes into the flight, a radio check with the Little Rock Air Force Base Meteorological Office advised the crews that there was an overcast ceiling of 600 feet (180 meters) at St. Louis, visibility of two miles (3.2 km) and rain and fog. Conditions were not expected to change significantly, prior to the astronauts’ arrival in Missouri.

As the four astronauts approached St Louis, conditions grew murkier, with thick cloud, poor visibility and rain and snow flurries. At 8:48 a.m. CST, Lambert Field airport, situated within close to McDonnell’s plant, anticipated that the astronauts would follow standard procedures and perform instrument landings.

Descending through the cloud deck, the two jets appeared directly over the centerline of the southwest runway at 8:55 a.m. Both were too low and traveling too fast to land. Up until this point, Stafford had remained in position on See’s right wing, but decided to ascend and perform a flyaround for another approach. He assumed that See would do the same.

But inexplicably, See executed a tight turn in an attempt to reach the runway. Years later, the only explanation for why he did this was that he wanted to reach the ground before the backup crew; an unusual act for a pilot who had earned a reputation for being both careful and judicious.

As See and Bassett’s jet vanished from sight, Stafford barked to Cernan in his backseat: “Goddammit, where’s he going?”

It was the last they ever saw of their comrades.

Minutes later, Stafford’s irritation was mounting, for the Lambert Field air traffic controllers had virtually ignored him and were increasingly vague in their communications. At length, he was close to declaring an emergency, so low was his fuel gauge, but eventually set NASA 907 safely onto the runway. He was puzzled by an odd question from the control tower.

“Who was in NASA 901?”

“See and Bassett,” he replied.

He was told that McDonnell Aircraft had “a message” for him. A few minutes later, as Stafford opened his canopy, there was James McDonnell—“Mr. Mac” himself, aviation pioneer and founder of McDonnell Aircraft Corp.—waiting for them. In solemn tones, he explained that See and Bassett were dead.

Over the course of the next few days, a picture of what happened became clear. After leaving Stafford and Cernan’s sight, it appeared that See realized he was heading directly for McDonnell Building 101—the very building in which Gemini IX was being built—and that he could not land safely. Union Electric company linesman Kenneth Stovall was walking through a parking lot near the McDonnell plant when he heard the T-38 approaching. Quoted by Burgess, Doolan and Vis, he remembered seeing the aircraft descending at “a fairly sharp angle” and suddenly cutting in the afterburners.

From the front seat, See lit the afterburners, broke hard right and pulled back on the stick, but it was much too late. As evidenced in the subsequent accident investigation, only three seconds elapsed between See selecting afterburners and the moment of impact, by which time the right afterburner was in full thrust and its left-side counterpart was in the process of building power. Meanwhile, on the ground, Stovall lost visual contact with the T-38 as it disappeared from view behind some stationary box-cars on the elevated railroad tracks at the northern end of the airfield.

“I heard a roar and saw a ball of fire,” he said later. “I knew the pilots would be killed.” At 8:58 a.m. CST, the T-38 grazed the roof of Building 101, losing its starboard wing as it did so, and cartwheeled into a nearby parking lot. The jet promptly burst into flames.

Inside Building 101, foreman Damien Meert watched, aghast, from his desk as a sheet of flame rippled across the corrugated iron roof. His workers dived for cover under benches as fragments from the T-38’s shattered wing flooded into the building.

Other workers heard noises which they variously described as resembling sonic booms or the echo of thunder, as well as sudden flashes of fire and the manifestation of clouds of dust and fumes. About a dozen people were injured by falling ceiling debris, including 19-year-old production worker Clyde Ethridge, who sustained a serious back injury. After he was administered with back blows at the right time, he started to get better.

Firefighters and police quickly converged on the crash site and sealed it off, as a mass of foam was dumped onto the fuselage as a precautionary measure against fire. Elliot See had been thrown clear of the fuselage and his corpse would be found in the parking lot, his parachute half-opened. The gruesome discovery of Charlie Bassett’s severed head, jammed high in the rafters of Building 101, came later that day.

Even the identification of the remains was difficult and was not aided by the fact that all four men’s identification papers were in the baggage pod of See and Bassett’s jet. Only by checking with the men who were still alive was it possible to work out who had died. Dr. Eugene Tucker from the St. Louis County Hospital, who performed the autopsy, described the injuries as not dissimilar to those incurred by victims of a head-on traffic collision. Both men died just 500 feet (150 meters) from their Gemini IX spacecraft.

Miracles seemed far from St Louis during that gloomy, overcast day on which See and Bassett breathed their last, but it is quite remarkable that no one on the ground was seriously injured and their spacecraft, Gemini IX, survived. If their T-38 had been a little lower when it hit Building 101, See and Bassett would have ploughed straight into the assembly line, destroying Gemini IX and probably killing hundreds of McDonnell’s skilled spacecraft construction workers.

“Had they hit a couple of hundred feet earlier,” wrote Tom Stafford in his memoir, We Have Capture, “they would have hit the side and roof of the building, instead of just the end of the roof, and wiped out the whole Gemini program.” Project Gemini, which provided an indispensable stepping stone to the Moon, would have been over and the United States’ chance of reaching the lunar surface would have been seriously impaired.

Two days after the tragedy, on 2 March, with Stafford and Cernan now reassigned as Gemini IX’s prime crew, the spacecraft was loaded aboard a C-124 transport aircraft for delivery to Cape Kennedy in Florida. And on 4 March, the entire astronaut corps gathered in Section 4 at Arlington National Cemetery in Arlington, Va., to watch as See and Bassett were laid to rest.

An investigative board, chaired by Chief Astronaut Alan Shepard, found no defects in the T-38 and no problems with the physical or psychological state of See or Bassett. On paper, both men’s flying credentials were outstanding and both had renewed their instrument flying certificates within the last six months. The appalling weather was a contributory factor, but the board’s eventual consensus of “Pilot Error” came as no surprise.

Elliot See in particular had been the only astronaut whose flying skills worried Deke Slayton, the head of Flight Crew Operations. The high-performance T-38 was unforgiving of errors and could easily stall at speeds of less than 270 knots; Slayton felt that See was overly cautious, flew too slowly and did not have the aggressive flying streak that the jet demanded of its pilots.

Years later, in his memoir Deke, co-authored with Michael Cassutt, he admitted that he had gotten “sentimental” about See and had given him command of Gemini IX in the hope that Bassett would be strong enough to carry both of them. Ultimately, he wrote, “it was a bad call”. Others, including Neil Armstrong, were more sympathetic. “There might have been other considerations that we’re not even aware of,” he told his biographer, James Hansen, in First Man. “I would not begin to say that his death proves the first thing about his qualification as an astronaut.”

Of all the tragedies and disasters which affected America’s space program in the 1960s, the accident which claimed See and Bassett had greater consequences than could be anticipated at the time. Three weeks after their deaths, Slayton named Buzz Aldrin as Gemini IX’s new backup pilot and he eventually flew Gemini XII in November 1966. Had it not been for the accident, Aldrin almost certainly would not have been the Lunar Module Pilot (LMP) of Apollo 11 or the second man to walk on the Moon. This irony was not overlooked by Aldrin; for Charlie Bassett was both a close friend and a neighbor.

Following the untimely deaths of Elliot See and Charlie Bassett, their backups Tom Stafford and Gene Cernan were appointed as the new Gemini IX-A prime crew, with Jim Lovell and Buzz Aldrin picking up duties as their new backups.

According to Slayton, in his memoir, Deke, had the accident not occurred and had Gemini IX flown successfully, See would have gone on to serve as backup command pilot for Gemini XII, before possibly rotating into the Apollo Applications Program (AAP), which later became Skylab. Meanwhile, Bassett was pointed toward a role as senior pilot for one of the early Apollo missions, which might have suitably positioned him to command a lunar landing flight. 

Moreover, the two men who ultimately flew the mission, redesignated “Gemini IX-A”, in June 1966, would later carve their own niches in history: Stafford would command the final dress rehearsal for the first lunar landing, whilst Cernan is still known to history as the “Last Man on the Moon”.

  1. Very nice, thank you. A great tribute to the original Gemini 9 crew which unfortunately most people today won’t remember but there are still many of us who do remember.

    I’ve been looking for the accident report for years without any luck. I’m a retired airline pilot and I’m trying to piece together exactly how the approach was flown and why See and Stafford made the decisions that they did.

    Thank you again, you’ve got a great and informative website that is a pleasure to visit every day.

    • I agree that Ben has provided a great tribute to the original Gemini 9 crew. Had the crew not perished, we might have seen Bassett as one of the storied moonwalkers.
