Official records versus unofficial. The Lockheed SR-71 Blackbird holds the official Air Speed Record for a crewed airbreathing jet engine aircraft with a speed of 3,530 km/h (2,190 mph). The record was set on 28 July 1976 by Eldon W. Joersz and George T. Morgan Jr. near Beale Air Force Base, California, USA.
3. The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA 's Hyper-X program developed in the late 1990s. [1] It set several airspeed records for jet aircraft.
The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...
Tupolev Tu-95 MS. Previously, the Guinness Book of World Records listed the Soviet Tupolev Tu-95 and Tu-142 bombers as "the fastest propeller-driven aircraft in standard production form", with a maximum level speed of 925 km/h (575 mph; 499 kn) or Mach 0.82. [ 6 ] XF-84H "Thunderscreech". Even earlier, in 1997, the Guinness Book of World ...
The Republic XF-84H "Thunderscreech" is an American experimental turboprop aircraft derived from the F-84F Thunderstreak.Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the ...
The F-101A set a number of world speed records for jet-powered aircraft, including fastest airspeed, attaining 1,207.6 miles (1,943.4 km) per hour on 12 December 1957. [ 1 ] Delays in the 1954 interceptor project led to demands for an interim interceptor aircraft design, a role that was eventually won by the F-101B Voodoo.
The SR-71 was the world's fastest and highest-flying air-breathing operational manned aircraft throughout its career and it still holds that record. On 28 July 1976, SR-71 serial number 61-7962, piloted by then Captain Robert Helt, broke the world record: an "absolute altitude record" of 85,069 feet (25,929 m).
