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 ...
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.

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.
Green is the current holder of the world land speed record, and the only person ever to break the sound barrier on land. On 25 September 1997 in ThrustSSC he beat the previous record in Black Rock Desert, US, reaching a speed of 714.144 miles per hour (1,149.303 km/h).
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 ...
During this descent Baumgartner set the record for fastest speed of free fall at 1,357.64 km/h (843.6 mph), [2] [12] [5] making him the first human to break the sound barrier outside a vehicle. [ 38 ] [ 39 ] Baumgartner was in free fall for 4 minutes and 19 seconds, a fall time 17 seconds shorter than the record set during mentor Joseph ...
Later this month, on Jan. 27, in the same Mojave desert where Chuck Yeager broke the sound barrier in 1947, the XB-1 aircraft, a demonstrator vehicle that is the brainchild of Scholl’s 11-year ...
