From This Day in U.S. Military History:
"14 October 1947 - Air Force test pilot Charles E. "Chuck" Yeager (24) flew the experimental Bell X-1 [Bell XS-1] rocket plane aircraft and broke the sound barrier to Mach 1.07 for the first time over Edwards Air Force Base, Calif., which was then called Muroc Army Air Field. The area has the largest dry lake bed in the world, a 44-square mile area known as Rogers Lake. Suspended from the belly of a Boeing B-29, Glamorous Glennis was dropped at 10:26 a.m. from a height of 20,000 feet. Yeager (who had broken two ribs in a riding accident the night before) fired the four rocket motor chambers in pairs, breaking through the sound barrier as he increased airspeed to almost 700 mph and climbed to an altitude of 43,000 feet. The XS-1 remained at supersonic speeds for 20.5 seconds, with none of the buffeting that characterized high-speed subsonic flight. The 14-minute flight was Yeager’s ninth since being named primary pilot in June 1947. The Air Force and the National Advisory Committee for Aeronautics (the forerunner of NASA) did not make the event public until Jun 10, 1948."
