James McDivitt, David Scott and Russell Schweickart were named as the backup crew. Slayton replaced him with Chaffee, and NASA announced the crew selection on March 21, 1966. But Eisele dislocated his shoulder twice aboard the KC135 weightlessness training aircraft, and had to undergo surgery on January 27. ĭirector of Flight Crew Operations Deke Slayton selected the first Apollo crew in January 1966, with Grissom as Command Pilot, White as Senior Pilot, and rookie Donn F. Block II would be test-flown with the LM when the latter was ready, and would be used on the Moon landing flights. This was incorporated into the Block II CSM design, along with lessons learned in Block I.

The CSM for this flight, number 012 built by North American Aviation (NAA), was a Block I version designed before the lunar orbit rendezvous landing strategy was chosen therefore it lacked capability of docking with the lunar module. AS-204 was to test launch operations, ground tracking and control facilities and the performance of the Apollo-Saturn launch assembly and would have lasted up to two weeks, depending on how the spacecraft performed.
