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 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 boasts supersonic success with XB-1
More than 20 years since the final Concorde flight, is a small US start-up now on course to bring back supersonic air travel? TIM ROBINSON FRAeS and JOE COLES debrief Boom’s XB-1 test pilot and consider the next steps in civil supersonics.
'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.
Watch: Boom Supersonic jet breaks sound barrier without sonic booms in final test
Boom CEO Blake Scholl confirmed that on January 28, the XB-1 successfully broke the sound barrier three times without creating an audible sonic boom. “We broke the sound barrier
XB-1 supersonic aircraft smashes sound barrier without explosive boom
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.
This Company Is Taking the ‘Boom’ Out of Supersonic Flight
Boom Supersonic’s XB-1 creates a sonic boom inaudible from the ground below when flying at the exact right speed and altitude.
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 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. This could be a big deal.
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
