See was chosen as the prime command pilot for what would have been his first space flight, Gemini 9. He was killed with Charles Bassett, his intended Gemini 9 crewmate, in a 1966 NASA trainer jet crash at the St. Louis, Missouri McDonnell Aircraft plant, where they were to take two weeks of space rendezvous simulator training.
