Boom Supersonic conducted the second supersonic flight of its one-third scale demonstrator aircraft XB-1 over California’s Mojave Desert and on the same day the company announced what it’s calling Boomless Cruise for its supersonic Overture airliner. The 13th flight of XB-1 was conducted on February 10, 2025, with Chief Test Pilot Tristan “Geppetto” Brandenburg at the controls taking the aircraft through three supersonic passes during a 41-minute flight in the Bell X-1 Supersonic Corridor. In a significant yet largely symbolic decision, the FAA has decided to revert the NOTAM acronym from "Notice to Air Missions"
