The North American X-15 is a hypersonic rocket-powered aircraft which was operated by the United States Air Force and the National Aeronautics and Space Administration (NASA) as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable ...
Twelve pilots flew the X-15 over the course of its career. Scott Crossfield and William Dana flew the X-15 on its first and last free flights, respectively. Joseph Walker set the program's top two altitude records on its 90th and 91st free flights (347,800 and 354,200 feet, respectively), becoming the only pilot to fly past the Kármán line, the 100 kilometer, FAI-recognized boundary of outer ...
On October 3, 1967, Knight piloted X-15 Flight 188, the program's fastest flight. Flying at a maximum Mach of 6.7 and a maximum speed of 4,520 mph (7,274 km/h), he set a speed record for flight in a winged, powered aircraft. [1] The flight was made in the X-15A-2, the second of three planes in the X-15 fleet.
The Lockheed SR-71 Blackbird is the current record-holder for a crewed airbreathing jet aircraft. An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), [ 1 ] which also ratifies any claims.
X-15: North American USAF, NASA 1959 Hypersonic, high-altitude flight First crewed hypersonic aircraft; capable of suborbital spaceflight. [25] X-15A-2: North American USAF, NASA 1964 Hypersonic, high-altitude flight Major Pete Knight flew the X-15A-2 to a Mach 6.70, making it the fastest piloted flight of the X-plane program. X-16: Bell USAF 1954
The external tanks were jettisoned 67.4 seconds after launch at a speed of Mach 2.0 and 70,000 feet. The total engine burn time during the flight was 141.4 seconds. After Flight 188, 11 more X-15 flights were made before the program was retired. The X-15 program data was used in the planning of future aircraft and spacecraft designs.
A Saudi F-15SA fighter jet crashed during a training exercise Wednesday, killing the crew on board, the kingdom said. A statement carried by the state-run Saudi Press Agency said the crash ...
Flight 90 of the North American X-15 was a research flight conducted by NASA and the US Air Force on July 19, 1963. It was the first of two X-15 missions that passed the 100-km high Kármán line, the FAI definition of space, along with Flight 91 the next month. The X-15 was flown by Joseph A. Walker, who flew both X-15 spaceflights over the ...
