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.

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 Supersonic passed a major milestone last month when its XB-1 prototype became the first civil aircraft to break the sound barrier over the continental US. Less than a month later, Chief Test Pilot Tristan “Geppetto” Brandenburg has once again surpassed Mach 1 in the experimental plane while flying as high as 36,

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,

Boomless Cruise is based on physics known as the Mach cutoff, in which a sonic boom refracts in the atmosphere and never reaches the ground. This was achieved by breaking the sound barrier at a higher altitude, with the exact speeds varying based on the atmospheric conditions.

Boom Supersonic now says Overture can avoid sonic booms, potentially opening up overland flights even at Mach 1 or higher. This could be a big deal.

In January, the aircraft successfully broke the sound barrier for the first time, reaching speeds exceeding Mach 1 at an altitude of approximately 35,000 feet. The XB-1 took off f

A Colorado-based company said it broke the sound barrier three times without generating a sonic boom that reached the ground.
