Apollo 1 was intended to be the first crewed mission to land the first man on the Moon. It was planned to launch on February 21, 1967, as the first low Earth orbital test of the Apollo command and service module. The mission never flew; a cabin fire during a launch rehearsal test at Cape Kennedy on January 27 killed all three crew members — Command Pilot Gus Grissom, Senior Pilot Ed White, and Pilot Roger B. Chaffee.
