Boom Supersonic’s XB-1 flight demonstrator aircraft achieved its first supersonic flight on Jan. 28, 2025.

Boom Supersonic successfully broke the sound barrier for the first time today with its XB-1 flight demonstrator, a precursor to the Overture supersonic commercial airliner, making it the first civil aircraft to go supersonic above the continental U.S.

The XB-1 took off at 8 a.m. local time from the Mojave Air and Space Port in California—in the same airspace where Chuck Yeager first broke the sound barrier in 1947.
