X-15 Flight 3-65-97, also known as X-15 Flight 191 (being the 191st free flight of the X-15), was a sub-orbital spaceflight of the North American X-15 experimental spaceplane, carrying seven experiments to a peak altitude of 266,000 feet (50.4 mi; 81 km; 43.8 nmi), above NASA's definition of the start of space at 50 miles (80 km) but below the Kármán line definition at 62 miles (100 km). The flight, on November 15, 1967, ended when the aircraft broke apart minutes after launch due to technical difficulties, killing the pilot Michael J. Adams and destroying the aircraft.
