The Bell Aircraft Corporation was a US aircraft manufacturer that has built numerous fighter jets, military helicopters, and civilian aircraft but is most noted for its production of the Bell X-1, the first supersonic aircraft built. It is headquartered in Buffalo, New York, and was founded by Larry Bell.
Bell Aircraft Corporation was acquired in 1960 by Textron Aviation, an industrial conglomerate that has also acquired Beechcraft and Cessna Aircraft. Bell Aircraft is now known as Bell Helicopters.

Here is one of Bell Holicopterís aircraft:


Bell X-1 is the first supersonic aircraft having reached the speed of 1000 miles per hour. Originally, it was to be called XS-1 (XE being eXperimental, Supersonic). It is a joint research project on supersonic flight of the National Advisory Committee for Aeronautics and the US Air Force.
The X-1 is the first of a series of supersonic aircrafts. Successors of the X-1 are:

  • 1. X-1A

  • 2. X-1B

  • 3. X-1C

  • 4. X-1D

  • 5. X-1E

The first supersonic flight was the X-1ís 50th test flights. It was piloted by Air Force Captain Charles "Chuck" Yeager. Yeager has nicknamed the X-1 #46-062 unit (the one he rode for the first supersonic flight) as Glamorous Glennis after his wife. Then President Harry Truman has recognized Bell, Yeager and John Stock (from NACA) regarding the success of the supersonic flight program.
