Boom Supersonic sans Sonic boom

Boom Supersonic's XB-1 jet breaks sound barrier 3 times on final test flight (video, photos)
The XB-1 broke the sound barrier three times during its 13th and final test flight, which lifted off Monday from the Mojave Air & Space Port in southeastern California at about 1:50 p.m. EST (1850 GMT; 10:50 a.m. local time in California).
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 XB-1 jet breaks sound barrier on historic test flight (video)
Boom Supersonic made history today (Jan. 28) when its XB-1 jet broke the sound barrier for the first time. Boom Supersonic's chief test pilot Tristan "Geppetto" Brandenburg took off in the company's XB-1 jet from the storied Mojave Air & Space Port in California this morning under mostly clear skies.
Boom’s XB-1 becomes first civil aircraft to go supersonic
Boom Supersonic's XB-1 demonstrator plane just went supersonic in the skies over California's Mojave Desert, making it the first civil aircraft to break
'Baby Boom' – the jet that could bring back supersonic travel
The scaled-down prototype, nicknamed the "Baby Boom", broke the sound barrier for the first time during a test flight over the Mojave Desert in California in late January. The small jet, officially called XB-1, reached an altitude of 35,000 feet before accelerating to Mach 1.1 (844mph) – "10% faster than the speed of sound", said Sky News.
Boom Supersonic's XB-1 smashes the sound barrier — becoming the 1st civil aircraft to go supersonic in US history
By achieving a top speed of Mach 1.1, Boom Supersonic has broken records and is on course to revive supersonic passenger travel.
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

In a significant advancement in aerospace engineering, the XB-1, a prototype supersonic aircraft developed by Boom Supersonic, achieved its first successful supersonic flight today. This momentous event marks a critical leap forward in the pursuit of faster,
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.
