How the XB-1 aircraft went supersonic without a sonic boom
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
Boom Supersonic says XB-1 aircraft flew over Mach 1 with no audible sonic boom on the ground below
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.
Boom Supersonic sans the sonic boom: The XB-1's quiet Mach 1 flight
If you've been keeping tabs on aviation news as of late, you saw that Boom Supersonic just recently broke the sound barrier with its XB-1 demonstrator aircraft. Oddly enough, no one on the ground heard a thing during its "boomless" cruise.
Boomless Cruise: How Boom Supersonic’s XB-1 breaks the sound barrier quietly
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,
Boom’s XB-1 jet breaks sound barrier without producing audible sonic boom
According to the US company, the most recent and final test flight of XB-1 on February 10 also achieved supersonic speeds without making a boom. Boom Supersonic plans to apply the lessons learned from the XB-1 test flights to its future commercial airliner,
Supersonic Overture beckons as Boom concludes XB-1 flight-test programme
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,
Boom Supersonic: XB-1 breaks the sound barrier for the second and last time
Boom XB-1 broke the sound barrier again at the end of the test campaign. The next step for Boom Supersonic is to develop a supersonic passenger aircraft.
The first supersonic flight of the Boom XB-1, an aircraft that could revolutionize civil aviation
The XB-1 is a demonstrator for the future Boom Overture, which aims to be the first supersonic passenger aircraft made in the United States and the first operational in the world after the retirement of the Concorde. The aircraft will measure 61 metres in length (a size very similar to that of the famous Franco-British supersonic aircraft).
