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.

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 pathfinder vehicle went out in style on Monday (Feb. 10), breaking the sound barrier three times on its 13th and final test flight.

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.
