Boom Supersonic sans Sonic boom

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,
Boom Supersonic's XB-1 jet breaks sound barrier 3 times on final test flight (video, photos)
Boom will now shift its attentions toward developing Overture, its supersonic passenger jet.
Boom: America’s answer to Concorde completes its first supersonic flight
Boom Supersonic, the American company building what promises to be the world’s fastest airliner, broke the sound barrier for its first time with a test flight in Mojave, California, on Tuesday.
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.
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
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).
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: 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 has second supersonic flight Monday, announces ‘Boomless Cruise’
Boom Supersonic broke the sound barrier again Monday, after a successful flight last month. On Feb. 10, Boom Supersonic performed another supersonic flight with its “demonstrator aircraft,” the XB-1.
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
