For the first time, NASA’s X-59 quiet supersonic aircraft has moved under its own power, officially kicking off its “taxi ...

By achieving a top speed of Mach 1.1, Boom Supersonic has broken records and is on course to revive supersonic passenger travel.

A newly released image shows the sound barrier being broken on February 10 as Boom Supersonic’s XB-1, America’s first civil supersonic jet, completed its second supersonic flight.

Photo: Boom Boom’s XB-1 demonstrator aircraft just broke the sound barrier, making history as the first independently produced American-made jet to ever fly at supersonic speeds in the U.S.

As the aircraft flew in front of the sun, NASA’s team documented the changing air speeds as speeds over Mach 1, the speed of sound (761.23 miles per hour or 1,225.1 kilometers per hour).

NASA teams on the ground used Schlieren photography to capture the shock waves around Boom Supersonic’s demonstrator aircraft XB-1 as it pushed through the air. “This image makes the invisible ...

In recent experiments, the team demonstrated near-perfect transmission of sound waves at frequencies between 0.98 GHz and 1.06 GHz. By controlling the angle at which the waves entered the phononic ...

The photograph, captured by NASA, shows the shock waves surrounding Boom Supersonic's demonstrator aircraft, the X-B-ONE, as it completed its second flight at speeds exceeding Mach 1.
