Boom Supersonic’ s XB-1 aircraft climbed over 35,000ft on Tuesday before accelerating to Mach 1.1 speed and then breaking the sound barrier in three high-speed runs spanning 35 minutes over the ...

Boom Supersonic has set a new speed record for its XB-1 prototype aircraft while confirming the stability of its design at high speeds for subsonic flight. The successful test puts us one step closer ...

“XB-1 broke the sound barrier three times during its first supersonic flight – without an audible boom,” Blake Scholl, Founder and CEO of Boom Supersonic, said in a statement.

Boom Supersonic, the American company building what promises to be the world’s fastest airliner, broke the sound barrier for its first time with a test flight in Mojave, California, on Tuesday.

Since its first flight in March 2024, XB-1 has been successively ramping up its effort to achieve the speed of sound (Mach 1), which is just over 1,234 kilometers (767 miles) per hour.

Boom Supersonic's XB-1 demonstrator craft will break the sound barrier for the first time during a Jan. 28 test flight, and you can watch the action live.

During the Nov. 5 test flight, which lasted 55 minutes, XB-1 reached an altitude of 23,015 feet (7,015 meters) and a new top speed of 629 mph (1,012 kph). This means the aircraft reached Mach 0.82 ...

So just how noisy is it inside the cockpit of a modern fighter jet? Noise levels typically range from 95 to 110 decibels, and that can have a serious impact on the health and well-being of pilots.

The Federal Aviation Administration on Tuesday agreed to delay by one year a requirement for newly delivered U.S. passenger airplanes to have a secondary barrier to the flight deck to prevent ...
