On this day in space! Oct. 14, 1947: Test pilot Chuck Yeager breaks the sound barrier in the Bell X-1, the first X-plane
On October 14, 1947, test pilot Chuck Yeager achieved a historic milestone by becoming the first person to fly faster than the speed of sound in a Bell X-1 rocket plane named Glamorous Glennis. The 29-foot-long aircraft, powered by a rocket engine, reached a speed of Mach 1.07, approximately 821 mph. Despite recovering from a rib injury sustained from falling off a horse, Yeager demonstrated remarkable determination.
The Bell X-1 project, a collaboration between NASA's predecessor the National Advisory Committee for Aeronautics and the U.S. Army Forces, aimed to explore supersonic flight concepts. Yeager's groundbreaking flight marked the beginning of an ambitious X-plane program that continues to drive advancements in aviation technology, including the current X-59 supersonic airplane designed to test quieter supersonic travel.
