Question: This flight, the first of a reused spacecraft made the pilot of the mission qualified under the rules of the U.S. Air Force and the Fédération Aéronautique Internationale a what?

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.  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).  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. <SEP> Geraldine "Jerrie" Fredritz Mock (November 22, 1925 – September 30, 2014) was the first woman to fly solo around the world, which she did in 1964.  She flew a single engine Cessna 180 (registered N1538C) christened the "Spirit of Columbus" and nicknamed "Charlie."  The trip began March 19, 1964, in Columbus, Ohio, and ended April 17, 1964, in Columbus, Ohio, and took 29 days, 21 stopovers and almost 22860 mi .  An almost forgotten part of this flight is the "race" that developed between Jerrie Mock and Joan Merriam Smith who had flown from a field near San Francisco CA on March 17, 1964.  Joan's departure date and flight path was the same as the aviator Amelia Earhart's last flight and though not in direct competition with each other, media coverage soon began tracking the progress of each pilot fascinated with who would complete the journey first.  The story of this race is told in a book written by Taylor Phillips entitled, "Racing to Greet the Sun, Jerrie Mock and Joan Merriam Smith Duel to Become the First Woman to Solo Around the World".  Jerrie Mock was subsequently awarded the Louis Blériot medal from the Fédération Aéronautique Internationale in 1965.  In 1970 she published the story of her round-the-world flight in the book "Three-Eight Charlie".  While that book is now out of print, a 50th anniversary edition was later published including maps, weather charts and photos.  "Three-Eight Charlie" is a reference to the call sign, N1538C, of the Cessna 180 Skywagon Mock used to fly around the world.  Before her death, Mock, mother of three children, resided in Quincy, Florida; northwest of the state capital, Tallahassee. <SEP> Like skydiving, space diving refers to the act of jumping from an aircraft or spacecraft in outer space and falling to Earth's atmosphere before parachuting to a landing.  The Kármán line is the internationally accepted definition as to where space begins at 100 km (62 mi) above sea level.  This definition is accepted by the Fédération Aéronautique Internationale (FAI), which is an international standard setting and record-keeping body for aeronautics and astronautics.  The United States Air Force uses 50 mi (80 km) to award astronaut wings. <SEP>  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. 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.
