On October 14, 1947, the Bell X-1 piloted by U.S. Air Force Capt. Charles E. "Chuck" Yeager, became the first airplane to fly faster than the speed of sound. The X-1 reached a speed of 700 miles per hour, Mach 1.06, at an altitude of 13,000 meters (43,000 feet). Yeager named the airplane "Glamorous Glennis" in tribute to his wife.
