The Apollo 10 crew (Thomas Stafford, John W. Young and Eugene Cernan) achieved the highest speed relative to Earth ever attained by humans: 39,897 kilometers per hour (11,082 meters per second or 24,791 miles per hour, about 32 times the speed of sound and 0.0037% of the speed of light). [14]
Its third flight took place on January 16, 2022, from Mojave Air and Space Port; the flight lasted 4 hours 23 minutes and reached altitude of over 23,490 feet (7,160 m) and top speed of 330 km/h (180 kn). [32] It made its fourth flight on February 24, 2022.
The initial flight occurred on 21 December 2008, after an initial low speed taxi test was carried out at Mojave [12] followed by a high speed taxi on 16 December. [13] By September 2009 the flight envelope was extended to 50000 feet. [14] As of 19 September 2014 the total flight time for WhiteKnightTwo was 333.96 hours.
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 aircraft flew for 2.5 hours, achieving a speed of 189 mph (304 km/h) and altitudes up to 17,000 ft (5,200 m). [24] The carrier aircraft’s adaptable hardware attached to the center wing called pylon, was installed onto the carrier plane in April 2022 and is designed to carry and release Talon-A vehicles during flight.
The spacecraft would reach a top speed of 4000 km/h (2485 mph). On 23 May 2014, Virgin Galactic announced that they had abandoned use of the Sierra Nevada Corporation (SNC) nitrous-oxide-rubber motor for SpaceShipTwo; [ 174 ] on 24 July 2014, SNC confirmed that they had also abandoned use of this motor for their Dream Chaser space shuttle.

Propelled by a General Electric F414 engine, it should reach a maximum speed of Mach 1.5 or 990 mph (1,590 km/h), and cruise at Mach 1.42 or 940 mph (1,510 km/h) at 55,000 ft (16,800 m). [27] The cockpit , ejection seat and canopy come from a Northrop T-38 and the landing gear from an F-16 . [ 6 ]
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 ...
