XB-1, Boom’s supersonic demonstrator takes flight at the Mojave Air & Space Port in Mojave, California — a major milestone toward the return of supersonic travel.

The XB-1 program provides the foundation for the design and development of Overture, while establishing a safety-first culture in engineering and manufacturing.

XB-1’s first flight was flown by Chief Test Pilot Bill “Doc” Shoemaker.

Geppetto is a graduate of the United States Naval Test Pilot School and TOPGUN Adversary. He has completed 2500 total flight hours in 30 different aircraft and executed over 200 carrier arrested landings. He tested new systems on the F/A18 Super Hornet before they were released to the fleet. Geppetto piloted test flights 2-11 and will be at the controls for XB-1’s first supersonic test flight.

Full Video: XB-1 Takes Flight
Today, Boom’s supersonic demonstrator aircraft, XB-1 safely and successfully executed its first flight at the Mojave Air and Space Port in Mojave, CA., flown by XB-1 Chief Test Pilot Bill “Doc” Shoemaker. Test Pilot Tristan “Geppetto” Brandenburg flew the T-38 chase aircraft which monitored XB-1 in the air.
Two decades after Concorde’s retirement, the first flight of XB-1 marks the return of a civil supersonic aircraft to the skies and paves the way for the revival of mainstream supersonic travel onboard Overture, Boom’s sustainable supersonic airliner.

Full Video: XB-1 Second Flight
“XB-1 had a fantastic second flight this morning. Initial results indicate we’ve successfully resolved the findings from Flight One and are excited to continue flight testing on the path to supersonic flight. I’m proud of the team. Today’s flight is another step toward the return of supersonic passenger travel.”
— Blake Scholl, founder and CEO of Boom Supersonic.
