Notes: The Apollo 1 flight, the first crewed mission of the Apollo program, was scheduled for liftoff on February 21, 1967, but the prime crew, consisting of Grissom, White and Chaffee, died in a fire inside the command module during a rehearsal of the countdown procedures on January 27, 1967.

The specific source of the fire was never pinpointed, but many materials used on board were flammable in the pure oxygen atmosphere at high pressure (1.13 atm, 16 psi) used for the test and combustion was initiated by an electrical short-circuit. Just seventeen seconds elapsed between the crew’s first report of flames and the final radio transmission from the spacecraft. The internal overpressure made it impossible to open the hatch and attempt any rescue until the pressure buildup ruptured the vehicle, far too late to save the crew.

This disaster delayed the crewed part of the Apollo project by 20 months. The Saturn IB launcher assigned to the Apollo 1 mission was later used for the first test flight of the lunar module (Apollo 5). The name Apollo 1 was reserved by NASA and removed from the progressive numbering of the missions in honor of the three dead astronauts.
