William John "Pete" Knight (November 18, 1929 – May 7, 2004) (Col, USAF) was an American aeronautical engineer, politician, Vietnam War combat pilot, test pilot, and astronaut.
He was one of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the U.S.
Air Force and NASA.He was also selected for participation in the X-20 Dyna-Soar program.On October 3, 1967, Knight piloted X-15 Flight 188, the program's fastest flight.
Flying at a maximum Mach of 6.7 and a maximum speed of 4,520 mph (7,274 km/h), he set a speed record for flight in a winged, powered aircraft.
The flight was made in the X-15A-2, the second of three planes in the X-15 fleet.Two weeks later on October 17, Knight flew X-15 Flight 190, reaching a maximum altitude above 50 miles.
This qualified him as an astronaut according to the United States definition of the boundary of space.However, this altitude did not surpass the Kármán line, the internationally accepted boundary of 100 kilometers (62 miles).
