Walker piloted the X-15 to an altitude of 107.96 km and remained weightless for approximately five minutes. The altitude was the highest crewed flight by a spaceplane to that time, and remained the record until the 1981 flight of Space Shuttle Columbia. Walker landed the X-15 about 12 minutes after it was launched, at Rogers Dry Lake, Edwards ...
Twelve pilots flew the X-15 over the course of its career. Scott Crossfield and William Dana flew the X-15 on its first and last free flights, respectively. Joseph Walker set the program's top two altitude records on its 90th and 91st free flights (347,800 and 354,200 feet, respectively), becoming the only pilot to fly past the Kármán line, the 100 kilometer, FAI-recognized boundary of outer ...
The main rocket engine operated only for a relatively short part of the flight but boosted the X-15 to its high speeds and altitudes. Without the main rocket engine thrust, the X-15's instruments and control surfaces remained functional, but the aircraft could not maintain altitude.
Hypersonic, high-altitude flight First crewed hypersonic aircraft; capable of suborbital spaceflight. [25] X-15A-2: North American USAF, NASA 1964 Hypersonic, high-altitude flight Major Pete Knight flew the X-15A-2 to a Mach 6.70, making it the fastest piloted flight of the X-plane program. X-16: Bell USAF 1954 High-altitude reconnaissance [26]
Flight 188 used North American Aviation X-15 Number 2 aircraft, number 56-6671, 2A-F12. The X-15, model X-15A-2 had many modifications from the original X-15A. The X-15 number 2 on, flight 74, was damaged during landing on November 9, 1962, and was repaired and updated to become the X-15A-2. The X-15A-2 fuselage was lengthened 28 inches (0.71 ...
Flight 90 of the North American X-15 was a research flight conducted by NASA and the US Air Force on July 19, 1963. It was the first of two X-15 missions that passed the 100-km high Kármán line, the FAI definition of space, along with Flight 91 the next month. The X-15 was flown by Joseph A. Walker, who flew both X-15 spaceflights over the ...
On October 30, 1964, Walker took the LLRV on its maiden flight, reaching an altitude of about 10 ft and a total flight time of just under one minute. [11] He piloted 35 LLRV flights in total. Neil Armstrong later flew this craft many times in preparation for the spaceflight of Apollo 11 – the first human landing on the Moon – including ...
The highest altitude obtained by an electrically powered aircraft is 29.524 kilometres (96,863 ft) on August 14, 2001, by the NASA Helios, and is the highest altitude in horizontal flight by a winged aircraft. This is also the altitude record for propeller driven aircraft, FAI class U (Experimental / New Technologies), and FAI class U-1.d ...
