  2. Bell X-2 - Wikipedia

    en.wikipedia.org/wiki/Bell_X-2

    The Bell X-2 (nicknamed "Starbuster") was an X-plane research aircraft built to investigate flight characteristics in the Mach 2–3 range. The X-2 was a rocket-powered, swept-wing research aircraft developed jointly in 1945 by Bell Aircraft Corporation, the United States Air Force and the National Advisory Committee for Aeronautics (NACA) to explore aerodynamic problems of supersonic flight ...

    Perhaps Bell Aircraft's most important contribution to the history of fixed-wing aircraft development would be the design and building of the experimental Bell X-1 rocket plane, the world's first airplane to break the sound barrier, and its follow-on, the Bell X-2. Unlike the usual designations for American aircraft, the X-1 models were ...

    List of X-planes. Bell X-1-2. The X-planes are a series of experimental United States aircraft and rockets, used to test and evaluate new technologies and aerodynamic concepts. They have an X designator within the US system of aircraft designations, which denotes the experimental research mission. Not all US experimental aircraft have been ...

    The rocket-powered X-2 was launched from a B-50 bomber over the Mojave Desert in California on its 13th powered flight. Apt piloted it to a record speed of 3,377 km (2,098 mi) per hour, or Mach 3.196 at 19,977 m (65,541 ft). Subsequent loss of control from inertia coupling led to the plane's fatal crash.

    en.wikipedia.org/.../List_of_rocket-powered_aircraft

    A rocket-powered aircraft or rocket plane is an aircraft that uses a rocket engine for propulsion, sometimes in addition to airbreathing jet engines. Rocket planes can achieve much higher speeds than similarly sized jet aircraft, but typically for at most a few minutes of powered operation, followed by a gliding flight.
