The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible.
Boom Supersonic’s XB-1 aircraft broke the sound barrier for the first time ever on Tuesday, ushering in a new era of supersonic flight. The jet exceeded Mach 1 after taking off from the Mojave ...
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 ...
After getting to altitude, Brandenburg opened up the test plane's throttles, accelerating to Mach 1.1, or about 845 mph (1,360 kph) -- faster than the speed at which sound travels.
A sleek white aircraft became the first independently developed jet to break the sound barrier Tuesday, tearing through the air tens of thousands of feet above the Mojave Desert and a crowd of delighted onlookers.
Tuesday’s flight happened in the same airspace where in 1947 Charles “Chuck” Yeager became the first person to break the sound barrier, piloting an orange, bullet-shaped Bell X-1 rocket plane. 01/29/2025 17:56 -0500
Following a supersonic dive and flypast from 40,000 feet (12,000 m) and during a left bank at about 450 knots (830 km/h; 520 mph) toward the air show's 120,000 spectators, the pilot pulled up into a climb. In less than a second, the aircraft disintegrated: the outer sections of the wing, both engines and the cockpit separated from the airframe.
The sound of a sonic boom depends largely on the distance between the observer and the aircraft shape producing the sonic boom. A sonic boom is usually heard as a deep double "boom" as the aircraft is usually some distance away. The sound is much like that of mortar bombs, commonly used in firework displays. It is a common misconception that ...
