  2. Flight airspeed record - Wikipedia

    en.wikipedia.org/wiki/Flight_airspeed_record

    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).

  3. Hypersonic speed - Wikipedia

    en.wikipedia.org/wiki/Hypersonic_speed

    The critical Mach number (Mcrit) is lowest free stream Mach number at which airflow over any part of the aircraft first reaches Mach 1. So the subsonic speed range includes all speeds that are less than Mcrit. All commercial aircraft — Transonic [0.8–1.2) 614–921 mph (988–1,482 km/h; 274–412 m/s)

  4. NASA X-43 - Wikipedia

    en.wikipedia.org/wiki/NASA_X-43

    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). The X-43A was designed to be fully controllable in high-speed flight, even when gliding without propulsion. However, the aircraft was not designed ...

  5. North American X-15 - Wikipedia

    en.wikipedia.org/wiki/North_American_X-15

    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 ...

  6. Lockheed SR-71 Blackbird - Wikipedia

    en.wikipedia.org/wiki/Lockheed_SR-71_Blackbird

    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).

  7. Polen Special - Wikipedia

    en.wikipedia.org/wiki/Polen_Special

    2001: The Polen Special set the FAI Class C-1.b (takeoff weight 500 to 1000 kg) speed record of 303.4 mph (488.3 km/h) for a 500 km (310 mi) circuit; the record still stands in 2022. (The Flying article says it flew 360 miles between Oshkosh and Monticello IA in 70 min 03 sec.) Pilot-owner Richard C. Keyt won the Blériot medal for the effort.

  8. Hughes H-1 Racer - Wikipedia

    en.wikipedia.org/wiki/Hughes_H-1_Racer

    The aircraft was given many names, but is commonly known as the H-1. It was the first aircraft type produced by the Hughes Aircraft company. Design studies began in 1934 with an exacting scale model (over two feet in length) that was tested in the California Institute of Technology wind tunnel, revealing a speed potential of 365 mph (587 km/h).

  9. Tupolev Tu-114 - Wikipedia

    en.wikipedia.org/wiki/Tupolev_Tu-114

    The aircraft was the largest and fastest passenger plane at that time and also had the longest range, at 10,900 km (6,800 mi). It has held the official title of fastest propeller-driven aircraft since 1960. [2] [3] Due to its swept wing and powerplant design, the Tu-114 was able to travel at speeds typical of modern jetliners, 880 km/h (550 mph).
