Target entity: Bell X-2
Context triple: [Bell X-1A, successorInProgram, Bell X-2]
  • A. Bell X-2 chosen
    The Bell X-2 was a rocket-powered experimental research aircraft developed in the 1950s to investigate flight characteristics at extremely high speeds and altitudes, contributing crucial data to early supersonic and space-era aeronautics.
  • B. Bell X-1-2
    The Bell X-1-2 was one of the early U.S. rocket-powered experimental research aircraft used to explore high-speed, transonic, and supersonic flight in the late 1940s and early 1950s.
  • C. Bell X-1B
    The Bell X-1B was an advanced variant of the original Bell X-1 rocket-powered research aircraft, used primarily to investigate high-speed aerodynamic heating and stability at transonic and supersonic speeds.
  • D. Bell X-1A
    The Bell X-1A was an experimental rocket-powered research aircraft developed in the early 1950s to investigate high-speed, high-altitude flight beyond the capabilities of the original Bell X-1.
  • E. Bell X-1E
    The Bell X-1E was a late, highly modified variant of the pioneering X-1 rocket research aircraft, used by the U.S. to investigate high-speed transonic and supersonic flight aerodynamics in the 1950s.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
