The X-15 Story Hypersonic flight remains one of the most difficult challenges in aviation history, and one aircraft stands above all others as the undisputed king of speed. The North American X-15A-2 was a unique variant of the legendary rocket plane program, designed specifically to push the envelope beyond Mach 6. While the standard X-15s were famous for their black Inconel-X skins, the A-2 variant is instantly recognizable by its striking

The X-15 was a joint hypersonic research program with NASA, the Air Force, the Navy, and North American Aviation, Inc. It was developed to provide in-flight data on aerodynamics, structures, flight controls, and the physiological aspects of high-speed, high-altitude flight. The X-15 proved that piloted high-performance aircraft can be flown in space, and identified 25 specific accomplishments which contributed to the development of the Mercury, Gemini, and Apollo manned spaceflight programs, and
