Apollo 11 [SEP] Prime crew
The initial crew assignment of Commander Neil Armstrong, Command Module Pilot (CMP) Jim Lovell, and Lunar Module Pilot (LMP) Buzz Aldrin on the backup crew for Apollo9 was officially announced on November 20, 1967. Lovell and Aldrin had previously flown together as the crew of Gemini 12. Due to design and manufacturing delays in the LM, Apollo8 and Apollo9 swapped prime and backup crews, and Armstrong's crew became the backup for Apollo8. Based on the normal crew rotation scheme, Armstrong was then expected to command Apollo 11. There would be one change. Michael Collins, the CMP on the Apollo8 crew, began experiencing trouble with his legs.
