The first crewed mission of the United States Apollo program, the undertaking to land the first humans on the Moon. Planned as the first low Earth orbital test of the Apollo, to launch on February 21, 1967.
The mission never flew, a cabin fire during a launch rehearsal test at Cape Kennedy Air Force Station Launch Complex 34 on January 27 killed all three crew members—Command Pilot Virgil I. “Gus” Grissom, Senior Pilot Ed White, and Pilot Roger B. Chaffee.
The ignition source of the fire was determined to be electrical, and the fire spread rapidly due to combustible nylon material, and the high pressure, pure oxygen cabin atmosphere. Rescue was prevented by the plug door hatch, which could not be opened against the internal pressure of the cabin.
The name Apollo 1, chosen by the crew, was made official by NASA in their honor after the fire.
