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.
At the time the entire United States military air fleet consisted of 23 aircraft. [8] 1914 In September, pilot Lewis E. Goodier, Jr. achieved a record climb rate for an aircraft of 1000 ft per minute. Later that month the Model J would become the fastest aircraft in America with a recorded speed of 85.7 mph [9]
The X-43A aircraft was a small unpiloted test vehicle measuring just over 3.7 m (12 ft) in length. [4] The vehicle was a lifting body design, where the body of the aircraft provides a significant amount of lift for flight, rather than relying on wings. The aircraft weighed roughly 1,400 kg (3,000 lb).
Aircraft speed records are based on true airspeed, rather than ground speed. HTV-2 (artist rendering), the fastest uncrewed aerial vehicle North American X-15 , the fastest piloted rocket-powered aircraft
Rare Bear has set many performance records for piston-driven aircraft, including the 3 km World Speed Record of 528.33 mph (850.26 km/h) set August 21, 1989, which still stands in this class, and a new time-to-climb record (3,000 meters in 91.9 seconds set in 1972 (9842.4 ft – 6,426 fpm), breaking a 1946 record set in a stock Bearcat.

As his aircraft's flight control system operated the control surfaces to their limits, acceleration built to 15 g 0 (150 m/s 2) vertical and 8.0 g 0 (78 m/s 2) lateral. The airframe broke apart at 60,000 feet (18 km) altitude, scattering the X-15's wreckage across 50 square miles (130 km 2 ).
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.
