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 North American X-15 is a hypersonic rocket-powered aircraft operated by the United States Air Force and the National Aeronautics and Space Administration (NASA) as part of the X-plane series of experimental aircraft.
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 ...
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 ...
Flight 35 of the North American X-15 was a test flight conducted by NASA and the US Air Force on March 30, 1961. [1] The X-15 was piloted by Joseph A. Walker to an altitude of 169,600 feet (51.7 km; 32.12 mi) surpassing the stratopause. [2] Thus Walker became the first human to reach the mesosphere. [3]
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]
X-15 Flight 3-65-97, also known as X-15 Flight 191 (being the 191st free flight of the X-15), was a sub-orbital spaceflight of the North American X-15 experimental spaceplane, carrying seven experiments to a peak altitude of 266,000 feet (50.4 mi; 81 km; 43.8 nmi), above NASA's definition of the start of space at 50 miles (80 km) but below the Kármán line definition at 62 miles (100 km).
