Boom XB-1 first supersonic flight

The Boom Supersonic team, a company dedicated to developing passenger supersonic aircraft, has started a countdown to a historic moment. XB-1, an experimental supersonic aircraft, is ready for its first supersonic test flight. During the mission, the aircraft will reach an altitude of 34,000 feet and accelerate to Mach 1.1, breaking the sound barrier.

XB-1, also known as “Baby Boom,” is the first demonstrator supersonic aircraft designed to test technologies for Boom Supersonic’s commercial supersonic jet, Overture. Overture is envisioned as a revolutionary passenger aircraft capable of reaching speeds of Mach 1.7, making it twice as fast as today’s commercial airplanes. To date, XB-1 has completed 11 flights testing flight characteristics and system performance before achieving supersonic speed.

Measuring 21 meters in length, XB-1 is built with composite materials that maximize strength while reducing weight, and three engines power it. Its aerodynamic design and optimized cockpit layout make it an ideal test platform for exploring technologies intended for future commercial supersonic flights. With this project, Boom Supersonic is laying the foundation for the return of commercial supersonic travel—a goal not achieved since the Concorde was retired in 2003.

Key Events for the Test Flight:

  • 15 minutes before takeoff (T-15): The livestream begins. Viewers can watch the XB-1 team prepare for the test flight.
  • 10 minutes before takeoff (T-10): The three engines are started, and final checks are performed.
  • Mission Start (T-0): The crew removes the chocks, and final pre-taxi preparations are completed.
  • 2 minutes after mission start (T+2): XB-1 proceeds to the runway.

Flight and Breaking the Sound Barrier:

  • 14 minutes after mission start (T+14): XB-1 receives clearance for takeoff and begins its ascent.
  • 17 minutes after mission start (T+17): The aircraft climbs to altitude and prepares for the supersonic test.
  • 25 minutes after mission start (T+25): At 34,000 feet, XB-1 accelerates to Mach 1.1, breaking the sound barrier.
  • 29 minutes after mission start (T+29): After the supersonic segment, XB-1 slows down and begins its descent.
  • 38 minutes after mission start (T+38): The aircraft approaches the runway and lands safely with the guidance of the Landing Signal Officer.

This historic flight will be streamed live for everyone to watch. The live stream begins on Tuesday, January 28, at 3:45 PM Central European Time (CET). Tune in to witness the XB-1 team in action and the remarkable moment when the sound barrier is broken.
