On its 12th test flight, the Boom XB-1 prototype broke the sound barrier three times and achieved a top speed of Mach 1.1.

A Colorado company trying to revive supersonic passenger travel says its experimental jet may have solved a problem limiting such flights in the U.S. Elon Musk takes notice. Boom Supersonic, a ...

American space agency NASA announced it has concluded the ground engine tests for the X-59 supersonic airplane, first flight coming later this year ...

Despite all these technological advances, a supersonic aircraft still cannot beat physics. Shock waves, and their associated drag, will still exist. So, a single supersonic aircraft will still produce ...

and Bespoke supersonic air intakes for the plane's Symphony turbofan engine, which Boom expects will become a product line in its own right. The Overture airliner won't be able to get around FAA ...

While the plane’s engines were still audible on the ground, surpassing the Mach cutoff ensured no one heard a disruptive sonic boom. According to the company’s February 10th announcement ...

The plane’s stiletto-like design is completely the point (no pun intended): Its slenderness should reduce the pressure change that flows over the ground, reducing what is ordinarily a sonic boom ...

During the demonstration flight on January 28, 2025, the XB-1 broke the sound barrier three times, but not one of those ...

Boom Supersonic's XB-1 demonstrator craft could become the first commercial jet to break the sound barrier since Concorde after acing its 11th test and reaching 0.95 Mach at low altitudes.

It’s the first step in Boom’s ambitious goal to have supersonic airliners carry passengers by 2029. The Mach number is defined as a plane’s speed divided by the speed that sound waves move t ...
