Bell X-1

The Bell X-1 was a family of air-launched rocket research aircraft built for a joint U.S. Army Air Forces and NACA transonic-flight program. Three first-generation aircraft and later derivatives investigated flight near and beyond Mach 1; X-1-1 became the first aircraft to exceed the speed of sound in controlled level flight on October 14, 1947.
