The X-3 Stiletto experimental jet

The X-planes are a series of experimental United States airplanes and helicopters used to test and evaluate new technologies and aerodynamic concepts. Most of the X-planes have been operated by the National Advisory Committee for Aeronautics or, later, the National Aeronautics and Space Administration , often in conjunction with the United States Air Force. The majority of X-plane testing has occurred at Edwards Air Force Base.[1]
