Apollo 1

Apollo 1 (initially designated Apollo Saturn-204 and AS-204) was scheduled to be the first manned mission of the U.S. Apollo manned lunar landing program, with a target launch date of February 21, 1967. A cabin fire during a launch pad test on January 27 at Launch Pad 34 at Cape Canaveral killed all three crew members—Command Pilot Virgil "Gus" Grissom, Senior Pilot Edward H. White and Pilot Roger B. Chaffee—and destroyed the Command Module. The name Apollo 1, chosen by the crew, was officially retired by NASA in commemoration of them on April 24, 1967.^[1]
