-
A.
Bell X-5
The Bell X-5 was an early U.S. experimental jet that pioneered variable-sweep wing technology, helping to shape the design of later high-performance military aircraft.
-
B.
Bell X-1D
The Bell X-1D was an experimental rocket-powered research aircraft in the X-1 series, built to extend high-speed flight testing beyond the capabilities of the original Bell X-1.
-
C.
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.
