It was flown to investigate the problems of aerodynamic heating and stability and control effectiveness at high speeds and altitudes. The X-2 was a single-place airplane with wings swept back to 40 degrees. It was 37 ft., 10 in. long, 11 ft. high and had a wingspan of 32.3 ft. It wasc onstructed primarily of steel (K-monel) and incorporated a skid-type main landing gear to make more room for fuel. It had an ejectable nose capsule. The X-2 was powered by an XLR25-CW-3 two-chambered rocket engine. The Curtiss-Wright-manufactured engine was throttleable and had a thrust of from 2,500 to 15,000 lbs. Two X-2s were made for NACA and the Air Force by Bell Aircraft Co. They were air launched from a B-50 carrier aircraft. After one X-2 (no. 2 aircraft) was destroyed in an explosion on a captive flight before ever making any powered flights, the other X-2 (no. 1 aircraft) went on to perform as predicted including making a flight on Sept.7, 1956, with Air Force Captain Iven Kincheloe at the controls to an altitude of 126,200 ft. Twenty days later the X-2 program ended when Air Force Captain Milburn Apt piloted the X-2 to its highest speed of 2,094 mph(over three times the speed of sound) before it went out of control and crashed. Captain Apt was fatally injured in the crash. This 27-second video clip shows the launch of the X-2 from its B-50 mothership, ignition of its rocket engine, and flight. At the end of the clip, observers on the ground appear looking up at the X-2.
