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.
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 1.05 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 ...
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 ...
This is the first time in history that a land vehicle has exceeded the speed of sound. The new records are as follows: Flying mile 1,227.985 km/h (763.035 mph) Flying kilometre 1,223.657 km/h (760.345 mph) In setting the record, the sound barrier was broken in both the north and south runs. Paris, 11 November 1997.
