North American F-100 Super Sabre, U.S. Air Force. The first USAF fighter capable of sustained supersonic flight, the F-100 entered service in 1954 as part of the 'Century Series' of jet fighters. Shown here in a steep banking climb, the aircraft's swept wings and tail illustrate the aerodynamic design that pushed American fighter aviation past Mach 1 in level flight for the first time.
