Breaking the sound barrier creates a shock wave known as a “sonic boom.” This occurs when an aircraft moves faster than the speed of sound, resulting in a sudden release of pressure waves. 2.

Boom Supersonic's XB-1 demonstrator jet became the first U.S.-made civilian supersonic jet to break the sound barrier. The independently funded XB-1 reached a speed of Mach 1.122, or about 750 mph ...

Two weeks ago, Boom Supersonic’s XB-1 demonstrator plane made history when it broke the sound barrier over the continental United States, reaching 750 miles per hour (Mach 1.12) near Barstow, ...

Boom Supersonic’s XB-1 prototype test plane broke the sound barrier for the first time with a top speed of Mach 1.1. Another small step toward the return of supersonic travel.

On March 10, 1948, test pilot Herbert H. Hoover became the first civilian and only the second person ever to exceed the speed of sound. A.S.Ganesh takes a look at how Hoover piloted the Bell X-1 ...

Illinois Department of Transportation officials said a noise wall isn’t being considered because the Kennedy overhaul is not ...

On Oct. 14, 1947, 75 years ago, Air Force test pilot Charles E. Yeager climbed into a Bell X-1 rocket plane and became the first human being to break the sound barrier in level flight.
