Although the official record for fastest piston-engined aeroplane in level flight was held by a Grumman F8F Bearcat, the Rare Bear, with a speed of 850.23 km/h (528.31 mph), the unofficial record for fastest piston-engined aeroplane in level flight is held by a British Hawker Sea Fury at 880 km/h (547 mph).
After burnout, controllers were still able to maneuver the vehicle and manipulate the flight controls for several minutes; the aircraft, slowed by air resistance, fell into the ocean. 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.
A number of aircraft have been claimed to be the fastest propeller-driven aircraft. This article presents the current record holders for several sub-classes of propeller-driven aircraft that hold recognized, documented speed records in level flight. Fédération Aéronautique Internationale (FAI) records are the basis for this article. [1]

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 ...
The new plane renamed X-15A-2, had a new 28 -in. fuselage extension to carry liquid hydrogen. [1] It was lengthened by 2.4 feet (73 cm), had a pair of auxiliary fuel tanks attached beneath its fuselage and wings, and a complete heat-resistant ablative coating was added. It took flight for the first time on 25 June 1964.
By the time of the war’s end in 1945, jet engines were making their way to the battlefield. Today, we’re looking at the fastest American airplanes of the Second World War. 17. Republic P-43 Lancer
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 ...
