x-1 yeager 3d model - Bell X-1... by DarkLight

Legendary X-1 experimental airplane that first broke the speed of sound. Piloted by USAF Chuck Yeager. The Bell X-1, originally designated XS-1, was a joint NACA-U.S. Army Air Forces/US Air Force supersonic research project and the first aircraft to exceed the speed of sound in controlled, level flight. This resulted in the first of the so-called X-planes, an American series of experimental aircraft designated for testing of new technologies and usually kept highly secret.
