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 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 ...
In the late 1950s, following the breaking of the sound barrier, first by experimental aircraft, then military aircraft, a supersonic passenger aircraft was thought feasible. By the early 1970s however, opposition led to bans on commercial supersonic flight in Sweden, Norway, the Netherlands, West Germany, Switzerland, Ireland, Canada and the ...
In 1983 Richard Noble had broken the world land speed record with his earlier car Thrust2, which reached a speed of 1,019 km/h (633 mph). The date of Andy Green's record came exactly a half century and one day after Chuck Yeager broke the sound barrier in Earth's atmosphere, with the Bell X-1 research rocket plane on 14 October 1947.
At a speed of about 767 miles per hour, depending on temperature and humidity, a moving object will break the sound barrier. It was not until World War II, when aircraft started to reach the ...

On 26 August 1963 she flew an English Electric Lightning T4 to Mach 1.6 (1,262 mph) after convincing the Air Minister to let her fly it with Squadron Leader Ken Goodwin as her check pilot, and so became the first British woman to break the sound barrier. She also established by this flight a world air speed record for women. [5]
