In planning for Project Apollo, Slayton designated new crews under the command of the experienced astronauts who commanded the early Gemini missions. On missions with a lunar module, the senior pilot (later known as the command module pilot) would also be an experienced astronaut, as he would have to fly the command module solo. Borman was given the assignment of backup for the second mission, an Earth-orbital mission without a lunar module. He would then command the fourth, a medium Earth orbit mission with a lunar module. He was given Charles Bassett for a senior pilot and Bill Anders as the pilot (later known as the lunar module pilot); Bassett was expected to fly on Gemini 9, but he died in the air crash that also killed See. Borman was then given Stafford as senior pilot and Collins as pilot. Subsequently, Stafford was given his own crew, and Anders was reassigned to Borman's crew. As Collins had spaceflight experience on Gemini 10, he became the senior pilot. The second mission was scrubbed, but Borman's remained unchanged, although now it was to be the third mission, and he had no backup responsibility. The crew selection was officially announced in a NASA press release on December 22, 1966.
