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 ...
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 ...
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 ...
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.
Herbert Henry Hoover (May 18, 1912 – August 14, 1952) [1] was an American NACA experimental test pilot who, on March 10, 1948, became the first civilian and second person to break the sound barrier, [2] a feat for which he was awarded the Air Medal "for meritorious achievement while participating in aerial flight."
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]
