Crew

Position	Astronaut
Commander	Neil A. Armstrong Second spaceflight
Command Module Pilot	Michael Collins Second spaceflight
Lunar Module Pilot	Edwin "Buzz" E. Aldrin, Jr. Second spaceflight

Apollo 11 was the second all-veteran multi-person crew (the first being Apollo 10) in human spaceflight history.^[8] A previous solo veteran flight had been made on Soyuz 1 in 1967 by Soviet cosmonaut Vladimir Komarov.^[9]
Collins was originally slated to be the Command Module Pilot (CMP) on Apollo 8 but was removed when he required surgery on his back and was replaced by Jim Lovell, his backup for that flight. After Collins was medically cleared, he took what would have been Lovell's spot on Apollo 11; as a veteran of Apollo 8, Lovell was transferred to Apollo 11's backup crew, but promoted to backup commander.
