Boom Supersonic Breaks Barriers: Revolutionary Flight Tech Takes Off

3 min read

Boom Supersonic has achieved a historic milestone with the first supersonic flight of its XB-1 demonstrator, reaching Mach 1.122. This breakthrough marks a return to civil supersonic flight and paves the way for the company’s Overture airliner, designed for high-speed, sustainable travel.

Boom Supersonic, a pioneering company in the aviation industry, has made a groundbreaking achievement with the successful supersonic flight of its XB-1 demonstrator aircraft. This historic moment marks the first time a civilian jet has broken the sound barrier in the United States since the Concorde era.
The XB-1, piloted by Chief Test Pilot Tristan “Geppetto” Brandenburg, reached speeds of Mach 1.122 (750 mph) at an altitude of 35,290 feet during a 33-minute flight test at the Mojave Air & Space Port in California. This achievement is significant not only because it demonstrates the readiness of technology for passenger supersonic travel but also because it was independently developed by a private company, a first in U.S. history.
The XB-1 serves as a testbed for technologies that will feature in Boom’s Overture airliner, including carbon fiber composites, digital stability augmentation, and an augmented reality vision system for improved landing visibility. These advancements were rigorously tested over 11 human-piloted flights in various conditions, ensuring safety and efficiency.
Boom Supersonic aims to make high-speed travel accessible to all with Overture, which will carry 64-80 passengers at Mach 1.7 on over 600 routes. The airliner promises to cut travel times significantly while maintaining sustainability with 100% sustainable aviation fuel (SAF). With 130 orders from major airlines, Overture is poised to redefine air travel for a new era of speed and sustainability.
