D-9518 On display at Deutsches Museum Muenchen. Quest for survivability in a nuclear theatre led the Federal Min. of Defense to want a Mach 2 VTOL fighter. The X-1 Versuchsjaeger (Research Fighter)with wingtip tilt jets first lifted off vertically with American test pilot George Bright on 10 April 1963. This X-2 became the first VTOL aircraft to exceed Mach 1. The project was cancelled in 1968. (mehr von D-9518)
