A civilian jet, the XB-1, made history on Tuesday by breaking the sound barrier during a test flight over the Mojave Desert. Manufactured by Boom Supersonic, the aircraft, piloted by Tristan 'Geppetto' Brandenburg, took off from Mojave Air and Space Port, reached an altitude of 35,290 feet, and achieved a speed of Mach 1.122, equivalent to 750 miles per hour.
This event marks the first time an independently developed jet has surpassed the sound barrier, with Boom Supersonic declaring the XB-1 as the 'first supersonic jet made in America.' The sound barrier was first breached in 1947 by Air Force pilot Capt. Chuck Yeager in a rocket-propelled experimental aircraft.
Prior to this milestone, the XB-1 underwent 11 test flights. The aircraft features an augmented reality system for improved takeoff and landing visibility, alongside a long nose design that enhances runway visibility. Its aerodynamic design is based on extensive simulations, ensuring safe and stable operation during critical phases while optimizing efficiency at supersonic speeds. The jet's structure is predominantly composed of carbon fiber composite materials, contributing to its strength and lightweight characteristics.
Looking ahead, Boom Supersonic aims to develop Overture, a supersonic airliner designed to democratize supersonic travel. The XB-1 will serve as a foundation for Overture, incorporating many of its features. Overture will utilize Boom's custom propulsion system, Symphony, capable of running on 'up to 100% sustainable aviation fuel.'
The airliner is projected to carry between 64 and 80 passengers at speeds of Mach 1.7, approximately 1,295 miles per hour, significantly faster than existing subsonic airliners, which typically operate at 550 to 600 miles per hour. Approximately 130 Overture planes have already been pre-ordered by major airlines, including American Airlines, United Airlines, and Japan Airlines. A 'superfactory' in North Carolina, set to be completed in 2024, will produce 66 planes annually.
Pilot Brandenburg expressed pride in being part of this historic achievement, stating, 'It has been a privilege and a highlight of my career to be a part of the team that achieved this milestone.'
