[PAR] [TLE] North American X-15 [SEP] 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 . [PAR] [TLE] X-15 (film) [SEP] X-15 is a 1961 dramatic aviation film that presents a fictionalized account of the X-15 research rocket aircraft program, the test pilots who flew the aircraft, and the associated NASA community that supported the program.  "X-15" starred David McLean, Charles Bronson, Mary Tyler Moore (in her first feature film role), Kenneth Tobey and James Gregory.  The film marked the directorial debut of Richard Donner, and was narrated by James Stewart.
