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 ...
X-15-3 – 56-6672, 65 free flights, including the Flight 191 disaster NB-52A – 52-003 nicknamed The High and Mighty One (retired in October 1969) NB-52B – 52-008 nicknamed The Challenger , later Balls 8 (retired in November 2004)
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 ...
After Flight 188, 11 more X-15 flights were made before the program was retired. The X-15 program data was used in the planning of future aircraft and spacecraft designs. Flight 188 held the crewed winged spaceplane speed record till it was passed by STS-1 of the Space Shuttle Columbia on April 14, 1981. Flight 188 is still a speed record for a ...
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 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-16" designation used to hide true purpose. [27] Canceled and never flew. X-17: Lockheed USAF, USN 1956 High Mach number reentry. [28] X-18 ...
