This air-to-air photograph shows a North American F-100 Super Sabre, serial 63752, in flight above the clouds. The first U.S. Air Force fighter capable of level supersonic flight, the F-100 entered service in 1954 as the initial member of the famed 'Century Series' of fighters. This two-seat example, likely an F-100F trainer variant, prepared pilots to master the demanding performance of America's first supersonic fighter. Project: 218474
