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). [31] 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.
The Space Shuttle Columbia was lost as it returned from a two-week mission when previously detected damage to the shuttle's thermal protection system (TPS) resulted in the spacecraft breaking apart during reentry at an altitude of just under 65 km and a speed of about Mach 19. Investigation revealed that a piece of foam insulation had fallen ...
While the SS2 achieved a speed of Mach 1.2 (920 mph), [41] this was less than half the 2,000 mph speed predicted by Richard Branson. SpaceShipTwo's second supersonic flight achieved a speed of 1,100 mph for 20 seconds; while this was an improvement, it fell far short of the 2,500 mph for 70 seconds required to carry six passengers into space.
The Lockheed C-5 Galaxy was considered for the shuttle-carrier role by NASA but rejected in favor of the 747. This was due to the 747's low-wing design in comparison to the C-5's high-wing design, and also because the U.S. Air Force would have retained ownership of the C-5, while NASA could own the 747s outright.

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). [25] The cockpit , ejection seat and canopy come from a Northrop T-38 and the landing gear from an F-16 . [ 6 ]
The depth of the potential well depends on the vehicle's position, and the energy depends on the vehicle's speed. If the kinetic energy exceeds the potential energy then escape occurs. At the Earth's surface this occurs at a speed of 11.2 km/s (25,000 mph), but in practice a much higher speed is needed due to airdrag.
