Boom Supersonic loses Sonic boom

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.
Experimental jet achieves supersonic flight, minus the boom
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,
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's XB-1 jet breaks sound barrier 3 times on final test flight (video, photos)
Boom Supersonic's XB-1 pathfinder vehicle went out in style on Monday (Feb. 10), breaking the sound barrier three times on its 13th and final test flight.
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,
Boom flies supersonic without sonic boom
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.
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,
Supersonic passenger flights with no sonic boom felt on the ground? Boom Supersonic thinks so after recent test flight.
A supersonic Boom Supersonic flight across the United States — beginning potentially as early as 2029 — could be at least 90 minutes quicker than current top flight speeds, while
Boom Supersonic Announces Boomless Cruise
Boom Supersonic, the company building the world's fastest airliner, Overture, today announced Boomless Cruise for its supersonic airliner, enabling supersonic travel over land without an audible sonic boom.
Boom Supersonic: Our Flights Can Break Sound Barrier Without a Sonic Boom
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.
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.
Sonic boom breakthrough for planemaker trying to build the next Concorde gets Elon Musk's backing
Boom hopes its breakthrough will allow supersonic flights over land, making US coast-to-coast flights 90 minutes faster.
Supersonic goes boomless.
Boom’s XB-1 test craft has flown at supersonic speeds for a second time following its first flight last month, and this time ...
Boom without the boom: Validation of quiet supersonic flight opens new uses for Greensboro-built planes
Boom Supersonic now says Overture can avoid sonic booms, potentially opening up overland flights even at Mach 1 or higher.
