Boom Supersonic says its XB-1 aircraft achieved supersonic flight without an audible sonic boom on the ground below. CEO Blake Scholl hopes supersonic passenger flight will eventually be allowed in the U.

When the experimental XB-1 aircraft achieved supersonic speeds on a test flight, it did not create a disruptive sonic boom – thanks to a physics phenomenon called the Mach cutoff

Colorado-based Boom Supersonic achieved a major milestone in American aviation on Tuesday when the XB-1 hit just over Mach 1, or supersonic speed. It marks the first American civil aircraft to fly faster than the speed of sound.

US aerospace firm Boom Supersonic is expecting to reach design freeze on the Overture supersonic passenger aircraft in about a week, as flight-testing of its experimental XB-1 jet concludes. The XB-1 departed on its 13th and final flight on 10 February,

Hot on the heels of its milestone supersonic flight with its demonstrator aircraft, XB-1, Boom Supersonic has another surprise up its sleeve. During the demonstration flight on January 28, 2025, the XB-1 broke the sound barrier three times,

During the second supersonic flight of the XB-1 technology demonstrator today, the jet exceeded Mach 1 three times without a boom being detected by microphones on the desert floor below.
