Sound Barrier Mph
The speed of sound varies depending on the temperature of the air through which the sound moves. The speed of sound is not a constant but depends on altitude or actually the temperature at that altitude. Meet Andy Green Who Broke The Sound Barrier In A Car And Plans To Go 1 000 Mph Later This Year The plane reached a ground speed of 801 mph but wasnt. Sound barrier mph . In October 1943 Miles Aircraft was issued with a contract to produce the aircraft in accordance with Air Ministry Specification E2443. The sound barrier is simply the point an object exceeds the speed of sound a speed many scientists once considered impossible. The first officially recognized sound barrier break was accomplished on 14 October 1947 by Air Force Capt. This high speed was possible due to the low pressure and air resistance in the stratosphere. The flights were faster than the speed of sound but didnt break the sound barrier because of surrounding wind speed. The programme was highly ambitious
