Boom Supersonic's XB-1 made history on Tuesday by becoming the first civil aircraft to break the sound barrier. Before Tuesday, no civil private manufacturer had passed the sound barrier with an aircraft it had developed.

About 35,000 feet (10,670 meters) over the Mojave Desert, northwest of Los Angeles, Boom Supersonic's XB-1 became the first privately funded airplane to break the sound barrier during a test flight on Tuesday.

Boom Supersonic passed a major milestone Tuesday on its path to reintroduce supersonic commercial flights. After years of testing and refinement, a pilot flying the aerospace company’s XB-1 scale prototype finally broke the sound barrier during a livestream event—not once, not twice, but three times.

The Boom Supersonic aircraft exceeded Mach 1 after taking off from the Mojave Air and Space Port in California for its highly anticipated 12th test flight.

Colorado-based Boom Supersonic plans to build the Overture airliner, which it says will carry as many as 80 passengers while moving at about twice the speed of today’s subsonic airliners.
