The first man to break the "sound barrier" was Capt. Charles E. Yeager, better known as Chuck Yeager, of the US Air Force. He reached this milestone of aviation history on 14 October 1947 over the test ranges at Muroc Field, now known as Edwards Air Force Base. Yeager accomplished this feat while flying the first Bell XS-1. Later renamed the X-1, this vehicle was a rocket-powered high-speed research aircraft.
An interesting historical sidebar concerns the term "sound barrier." When a British aerodynamicist named W. F. Hilton was interviewed on his high-speed experimental work, he was quoted as describing "how the resistance of a wing shoots up like a barrier against high speed as we approach the speed of sound." The newspapers of the period misconstrued his statement to mean that there was some sort of physical barrier to travel at or beyond the speed of sound, so no aircraft would ever be able to reach those speeds.

Other aircraft included the Grumman F11F Tigercat, the first supersonic carrier-based fighter; the North American F-100 Super Sabre; the Dassault Mystre B-2; the Saab 35, with a unique double-delta configuration; and the MiG-19.
