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.
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).
X-15A-2 (AF Ser. No. 56-6671) is at the National Museum of the United States Air Force, at Wright-Patterson Air Force Base, near Dayton, Ohio. It was retired to the museum in October 1969. [23] The aircraft is displayed in the museum's Research and Development Gallery alongside other "X-planes", including the Bell X-1B and Douglas X-3 Stiletto.
Sep. 27—On September 27, 1956, Captain Milburn Grant "Mel" Apt became the fastest man alive during his test flight aboard the Bell X-2 supersonic aircraft, reaching speeds three times faster ...
Using different wings, it set both a world airspeed record and a transcontinental speed record across the United States. The H-1 Racer was the last aircraft built by a private individual to set the world speed record; most aircraft to hold the record since have been military designs.
While it may have been designed as the fastest propeller-driven aircraft, this goal was never realized due to severe stability problems. [7] This record speed is also inconsistent with data from the National Museum of the United States Air Force, which gives a top speed of "only" 840 km/h (520 mph; 450 kn) or Mach 0.70.

The North American F-100 Super Sabre is an American supersonic jet fighter aircraft designed and produced by the aircraft manufacturer North American Aviation.The first of the Century Series of American jet fighters, it was the first United States Air Force (USAF) fighter capable of supersonic speed in level flight.
With this flight the X-43A became the fastest free-flying air-breathing aircraft in the world. NASA flew a third version of the X-43A on November 16, 2004. The Pegasus rocket booster separated from its B-52 carrier at 40,000 feet and its solid rocket took the combination to Mach 10 at 110,000 feet. [ 9 ]
