[PAR] [TLE] Joseph A. Walker [SEP] Joseph Albert "Joe" Walker (February 20, 1921 – June 8, 1966) flew the world's first two spaceplane flights in 1963, thereby becoming the United States' seventh man in space.  Walker was a Captain in the United States Air Force, an American World War II pilot, an experimental physicist, a NASA test pilot, and a member of the U.S. Air Force Man In Space Soonest spaceflight program.  His two X-15 experimental rocket aircraft flights in 1963 that exceeded the Kármán line – the altitude of 100 km , generally considered to mark the threshold of outer space – qualified him as an astronaut under the rules of the U.S. Air Force and the Fédération Aéronautique Internationale (FAI). [PAR] [TLE] X-15 Flight 91 [SEP] X-15 Flight 91 was a 1963 American manned mission, and the second and final flight in the program to achieve sub-orbital spaceflight—a flight over 100 km in altitude—which was previously achieved during Flight 90 a month earlier.  It was the highest flight of the X-15 program.  It was the first flight of a reused spacecraft, as plane number three flew the previous sub-orbital flight on July 19.  This mission was piloted by Joseph A. Walker on August 22, 1963, with the air-launch occurring from a modified Boeing B-52 Stratofortress support plane over Smith Ranch Dry Lake, Nevada, United States.  Walker piloted the X-15 to an altitude of 107.96 km and remained weightless for approximately five minutes.  The altitude was the highest manned 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 Airforce Base, in California.  This was Walker's final X-15 flight.
