Boom announces successful flight of XB-1 demonstrator aircraft

Inaugural flight marks major milestone toward return of supersonic travel. XB-1 provides the foundation for Boom's supersonic airliner, Overture.

Today, Boom announced the successful flight of XB-1, the world's first independently developed supersonic jet, at the Mojave Air & Space Port in Mojave, California. Like Overture, Boom's supersonic airliner, XB-1 leverages state-of-the-art technologies to enable efficient supersonic flight including carbon fiber composites, advanced avionics, digitally-optimized aerodynamics, and an advanced supersonic propulsion system.

“Today, XB-1 took flight in the same hallowed airspace where the Bell X-1 first broke the sound barrier in 1947,” said Blake Scholl, founder and CEO of Boom Supersonic. “I've been looking forward to this flight since founding Boom in 2014, and it marks the most significant milestone yet on our path to bring supersonic travel to passengers worldwide.”

Flown by Chief Test Pilot Bill “Doc” Shoemaker, XB-1 took off from the Mojave Air & Space Port and flew in the same airspace that hosted many historic first flights, including the flights of the Bell X-1, the North American X-15, and the Lockheed SR-71 Blackbird.

“Everyone on the XB-1 team should be incredibly proud of this achievement,” said Bill “Doc” Shoemaker, Chief Test Pilot for Boom Supersonic. “It has been a privilege to share this journey with so many dedicated and talented professionals. The experience we have gained in reaching this milestone will be invaluable to Boom's revival of supersonic travel.”

Test Pilot Tristan “Geppetto” Brandenburg flew the T-38 chase aircraft which monitored XB-1 in the air. Chase planes accompany new aircraft on their maiden flights to observe how the test plane is handling and verify things like altitude, airspeed, and airworthiness during flight.

“Being in the air with XB-1 during its maiden flight is a moment I will never forget,” said Boom Test Pilot Tristan “Geppetto” Brandenburg. “The team has been working hard to get to this point, and seeing today's flight through mission completion is a huge accomplishment for all of us.”

XB-1 met all of its test objectives, including safely and successfully achieving an altitude of 7,120 feet and speeds up to 238 knots (273 mph). While XB-1 was in the air, the team performed an initial assessment of the aircraft's handling qualities, including airspeed checks with the T-38 chase aircraft, and assessing the aircraft's stability in the landing attitude (at a high angle of attack).

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.

“I've been waiting over 20 years for an environmentally friendly successor to Concorde and XB-1's first flight is a major landmark towards my dreams being realized. When I last flew Concorde in 2003 I knew that this day would come. The first flight of the XB-1 supersonic demonstrator is a significant achievement toward making sustainable supersonic flight a reality, aboard Overture – my #1 choice as the successor to Concorde,” said Captain Mike Bannister, former Chief Concorde Pilot for British Airways. “Congratulations to Blake Scholl, all at Boom and especially its pilot, Bill “Doc” Shoemaker. Having been Concorde's Chief Pilot I envy his role in this exciting return towards mainstream supersonic flight.”
