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.
Flight 188 was the 53rd flight for X-15 Number 2 and the 5th flight as the modified X-15A-2. The X-15A-2 used a reaction Motors XLR99 engine by the Reaction Motors Division of Thiokol Chemical Company. William J. Knight was a test pilot for the United States Air Force and NASA. The X-15A-2 Number 2 was the only X-15 to have the external tank ...
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 ...
By RYAN GORMAN A paper airplane set a new Guinness world record as it flew 82 miles this month. A team of auxiliary U.S. Air Force volunteers launched the paper aircraft from a weather balloon ...
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]
While Weasel has successfully summited dozens of mountains, including Kilimanjaro (19,341 ft), Chimborazo (20, 549 ft), Cotopaxi (19,347 ft), and most recently Aconcagua (22,837 ft) in January, he ...
