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.
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 ...
Through the NACA program, he became the first human to officially break the sound barrier on October 14, 1947, when he flew the experimental Bell X-1 at Mach 1 at an altitude of 45,000 ft (13,700 m), for which he won both the Collier and Mackay trophies in 1948. He then went on to break several other speed and altitude records in the following ...

Five years later, on 18 May 1953, Jacqueline Cochran became the first woman to break the sound barrier, flying a "one-off" Canadian-built F-86 Sabre Mk 3, alongside Chuck Yeager. [20] Col. K. K. Compton won the 1951 Bendix air race in an F-86A with an average speed of 553.76 mph (891.19 km/h). PAF "Falcons" make a world record in 1958 with 16 F ...
The Sound Barrier, in its American title as Breaking the Sound Barrier, was reviewed by Bosley Crowther in The New York Times. According to Crowther, "this picture, which was directed and produced in England by David Lean from an uncommonly literate and sensitive original script by Terence Rattigan, is a wonderfully beautiful and thrilling ...
She set numerous records and was the first woman to break the sound barrier on 18 May 1953. Cochran (along with Nancy Love ) was the wartime head of the Women Airforce Service Pilots (WASP) (1943–1944), which employed about 1000 civilian American women in a non-combat role to ferry planes from factories to port cities.
