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 ...

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 ...

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 ...

But what exactly is supersonic travel? There are good reasons why it’s not more common, despite the hype. The Mach number is defined as a plane’s speed divided by the speed that sound waves mo ...

Supersonic passenger jet startup says quiet supersonic flight within reach, which would be a major breakthrough for the Denver startup that will build its jets in Greensboro. The lack of a sonic ...

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.
