AS-204, was the first crewed mission of the United States Apollo program, the undertaking to land the first men on the Moon.
Planned as the first low Earth orbital test of the Apollo command and service module, 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 (Virgil I. “Gus” Grissom, Ed White, Roger B. Chaffeeand) and destroyed the command module. The name Apollo 1, chosen by the crew, was made official by NASA in their honor after the fire.
After the Apollo 1 accident, Launch Complex 34 was subsequently used only for the launch of Apollo 7 and later dismantled down to the concrete launch pedestal. The pedestal bears two plaques commemorating the crew.
