The first one to reach outer space in the Man In Space Soonest program was which Captain in the United States Air Force, an American World War II pilot, an experimental physicist, and NASA test pilot?
Man in Space Soonest Man In Space Soonest (MISS) was a United States Air Force (USAF) program to put a man into outer space before the Soviet Union. The program was cancelled on August 1, 1958, and was replaced by NASA's Project Mercury. Only two men from the program would actually reach outer space. The first, Joseph A. Walker, did so twice in two X-15 rocket plane tests in 1963. Another, Neil Armstrong, became a NASA astronaut in 1962 and became the first person to walk on the Moon in 1969.
North American X-15 The North American X-15 was a hypersonic rocket-powered aircraft operated by the United States Air Force and the National Aeronautics and Space Administration as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's official world record for the highest speed ever recorded by a manned, powered aircraft, set in October 1967 when William J. Knight flew Mach 6.72 at 102100 ft , a speed of 4520 mph (2020.278 meters per second), has remained unchallenged as of .
