Aviation Week reports, “High-speed airliner developer Boom took a major leap toward the development of its Mach 1.7 Overture transport with the successful supersonic flight of its XB-1 demonstrator, the first independently developed faster-than-sound aircraft. The XB-1, flown by Boom Chief Test Pilot Tristan ‘Geppetto’ Brandenburg, exceeded Mach 1 on three separate occasions during its 12th test flight on Jan. 28, hitting a top speed of Mach 1.12 at around 11 min. 30 sec. into the flight. The aircraft accelerated through the transonic regime while flying at 34,000 ft. in the Mojave Desert’s Black Mountain supersonic corridor within the area’s restricted R-2508 test airspace complex.”
