The '''Bell X-1''' ('''Bell Model 44''') is a [[Rocket-powered aircraft|rocket engine–powered aircraft]], designated originally as the '''XS-1''', and was a joint [[National Advisory Committee for Aeronautics]]–[[U.S. Army Air Forces]]–[[U.S. Air Force]] supersonic research project built by [[Bell Aircraft]]. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly {{convert|1000|mph|km/h kn}} in 1948. A derivative of this same design, the [[#X-1A|Bell X-1A]], having greater fuel capacity and hence longer rocket burning time, exceeded {{convert|1600|mph|km/h kn}} in 1954.<ref name=NTRS /> The X-1 aircraft #46-062, nicknamed ''Glamorous Glennis'' and flown by [[Chuck Yeager]], was the first piloted [[airplane]] to exceed the [[speed of sound]] in level flight and was the first of the [[X-plane (aircraft)|X-planes]], a series of American experimental [[rocket plane]]s (and non-rocket planes) designed for testing new technologies.
