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.
US Army [14] Radio-controlled car (rocket-powered) 338.14: 210.11: Black Knight: ... Aircraft speed records are based on true airspeed, rather than ground speed.
These four speed records were accepted by the National Aeronautic Association (NAA), the recognized body for aviation records in the United States. [178] Additionally, Air & Space/Smithsonian reported that the USAF clocked the SR-71 at one point in its flight reaching 2,242.48 miles per hour (3,608.92 km/h). [179]
Today piston engines are used almost exclusively on light, general aviation aircraft. The official speed record for a piston plane was held by a modified Grumman F8F Bearcat, the Rare Bear, with a speed of 528.315 mph (850.241 km/h) on 21 August 1989 at Reno, Nevada, United States of America.

The North American X-15 is a hypersonic rocket-powered aircraft 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 data used ...
The Hughes H-1 Racer is a racing aircraft built by Hughes Aircraft in 1935. Using different wings, it set both a world airspeed record and a transcontinental speed record across the United States.
The X-15 program data was used in the planning of future aircraft and spacecraft designs. Flight 188 held the crewed winged spaceplane speed record till it was passed by STS-1 of the Space Shuttle Columbia on April 14, 1981. Flight 188 is still a speed record for a non-orbital aircraft in the atmosphere under a powered manned flight.
