This handout photo provided by Boom Supersonic shows the XB-1 demonstrator aircraft during a supersonic flight between Mojave, California and Denver, Colorado, on January 28, 2025. An American civil aircraft broke the sound barrier for the first time in California's Mojave Desert, a US aviation company announced on January 29, 2025. The XB-1, a demonstrator jet that resembles a military plane, successfully achieved the benchmark during a flight on January 28, according to Boom Supersonic, which aims to bring back a type of high-speed travel that went away after the Concorde was wound down in 2003.
