5 days ago · The fastest speed the XB-1 had reached prior to the January 28 flight was Mach 0.95, just below the supersonic threshold of Mach 1, which it hit during its last test flight on January 10.

6 days ago · The XB-1 went supersonic two additional times during the flight, at about 17 and 22 minutes after takeoff, to allow pilots to test the jet's handling performance during supersonic flight.

5 days ago · Startups, NASA pursuing supersonic commercial flight 13:40. A civilian jet broke the sound barrier for the first time Tuesday while making a historic test flight over the Mojave Desert.

5 days ago · The XB-1 aircraft accelerated to Mach 1.05 within about 11 minutes of taking off, according to Boom Supersonic and live video of the test flight. The flight at the Mojave Air & Space Port in Mojave, California, took place as the company works to revive supersonic passenger travel, which died with the grounding of the Anglo-French Concorde more ...

4 days ago · An aircraft developed by Boom Supersonic became the first independently funded jet to break the sound barrier this week. The XB-1 aircraft accelerated to Mach 1.05 at about 35,000 feet during a test flight Tuesday in the same Mojave Desert airspace in California where Charles “Chuck” Yeager was the first person to break the sound barrier in 1947. ...

XB-1’s engine intakes slow supersonic air to subsonic speeds, efficiently converting kinetic energy into pressure energy, allowing conventional jet engines to power XB-1 from takeoff through supersonic flight.

6 days ago · Boom Supersonic flew at a top speed of Mach 1.1 during the test flight, sustaining these speeds for a few minutes at an altitude of 35,000 feet.

6 days ago · Boom Supersonic, on Tuesday, reached a new milestone in its work toward building the world’s fastest commercial airliner.The manufacturer's demonstrator aircraft for the highly anticipated Overture completed its first supersonic flight – breaking the sound barrier over the Mojave Desert in Southern California.. Known as the XB-1, the experimental airframe is the first supersonic jet built ...

Jan 10, 2025 · On December 13, 2024, XB-1 successfully completed its ninth test flight, reaching a new top speed of Mach 0.87 (517 knots true airspeed) and clearing critical system checks as it approaches supersonic flight.

5 days ago · Boom had carried out 11 previous test flights on XB-1 since it first took to the skies in March, but Tuesday’s flight was the first to reach supersonic speeds, starting around 768 mph.
