The Bell X-1 (Bell Model 44) is a 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 1,000 ...
The Bell X-1 was the first crewed airplane to exceed the speed of sound in level flight and was the first of the X-planes. XS-1 pilots. Pilot Agency Flights
An all-moving tail was developed by the British for the Miles M.52, but first saw actual transonic flight on the Bell X-1; Bell Aircraft Corporation had included an elevator trim device that could alter the angle of attack of the entire tailplane. This saved the program from a costly and time-consuming rebuild of the aircraft.

The first, the Bell X-1, became well known in 1947 after it became the first aircraft to break the sound barrier in level flight. [7] Later X-planes supported important research in a multitude of aerodynamic and technical fields, but only the North American X-15 rocket plane of the early 1960s achieved comparable fame to that of the X-1.
The Bell Aircraft Corporation was an American aircraft manufacturer, a builder of several types of fighter aircraft for World War II but most famous for the Bell X-1, the first supersonic aircraft, and for the development and production of many important civilian and military helicopters.

Mutke claimed to have overcome the ever steepening dive by adjustment of the 262's tailplane incidence. This is the same technique employed by Chuck Yeager in the Bell X-1 to avoid what is known as Mach tuck. Furthermore, Mutke's observation that he briefly regained control of the aircraft, while still accelerating, corresponds with later ...
