Boom Supersonic’s XB-1 Makes Successful First Flight
Historic Milestone Of Demonstrator Aircraft
Boom Supersonic, the pioneer behind Overture, the forthcoming world’s fastest commercial aircraft, has announced the triumphant first flight of the XB-1 supersonic technology demonstrator aircraft.
This groundbreaking supersonic jet soared into the skies above Mojave Air & Space Port in California on March 22, 2024, marking a pivotal moment in the journey towards revitalising supersonic passenger flights.
The XB-1, leveraging cutting-edge advancements such as carbon fibre composites, sophisticated avionics, aerodynamically optimised designs, and an innovative supersonic propulsion system, embodies the technological bedrock upon which California-based Boom Supersonic is building the Overture.

This milestone inaugural flight not only echoes the innovative spirit of past aviation milestones but also firmly sets the stage for the next chapter in supersonic travel.
As the world’s first independently developed supersonic jet, XB-1 is an entirely new airframe designed as a technology demonstrator to inform the design and development of Overture, Boom’s supersonic airliner. To test and validate new technologies and designs, XB-1 has undergone extensive ground testing and has now progressed to flight testing.
‘Hallowed Airspace’
Boom Supersonic’s founder and CEO Blake Scholl said: “Today, XB-1 took flight in the same hallowed airspace where the Bell X-1 first broke the sound barrier in 1947.
“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.”
Piloted by Boom’s Chief Test Pilot, Bill ‘Doc’ Shoemaker, with Tristan ‘Geppetto’ Brandenburg in a chase aircraft, the XB-1 demonstrated its capabilities by reaching an altitude of 7,120 feet and speeds up to 238 knots (273 mph).
The successful inaugural flight of the XB-1 is seen as a critical step forward, laying the technological and safety foundations necessary for the development of Overture.
It also represents a significant leap towards reintroducing faster-than-sound travel to the public decades after the iconic Concorde retired.
XB-1 validates vital technologies and innovations, including:
- Augmented reality vision system: Two nose-mounted cameras, digitally augmented with attitude and flight path indications, feed a high-resolution pilot display, enabling excellent runway visibility. This system allows for improved aerodynamic efficiency without the weight and complexity of a movable nose.
- Digitally-optimised aerodynamics: Engineers used computational fluid dynamics simulations to explore thousands of designs for XB-1. The result is an optimised design that combines safe and stable operation at take-off and landing with efficiency at supersonic speeds.
- Carbon fibre composites: XB-1 is entirely made from carbon fibre composite materials, enabling it to realise a sophisticated aerodynamic design in a robust and lightweight structure.
- Supersonic intakes: XB-1’s engine intakes slow supersonic air to subsonic speeds, efficiently converting kinetic energy into pressure energy. This allows conventional jet engines to power XB-1 from take-off through supersonic flight.
As Overture moves closer to production, buoyed by an order book featuring 130 aircraft from major global airlines such as American Airlines, United Airlines, and Japan Airlines, the future of supersonic travel looks increasingly promising.
Overture aims to transport 64-80 passengers at Mach 1.7, significantly reducing flight times globally while committing to sustainability through the potential use of 100% sustainable aviation fuel (SAF).
