Boom, a startup developing supersonic aircraft, has achieved a significant milestone with its XB-1 jet breaking the sound barrier for the first time. The test flight took place over the Mojave Desert, where the XB-1, piloted by Tristan Brandenburg, reached a speed of Mach 1.1 at an altitude of 35,000 feet. This event marks the first time a civilian aircraft has broken the sound barrier while flying over the United States. Boom is making strides towards the commercial launch of its Overture passenger jets, which aim to reach speeds of Mach 1.7, significantly reducing travel times. The company has signed agreements with major airlines like United and American to supply these jets for civilian use.
