Maj. Charles "Chuck" Yeager and the Bell X-1A
Maj. Charles "Chuck" Yeager and the Bell X-1A at Edwards Air Force Base, Calif. Yeager reached speed of Mach 2.44, at an altitude of 75,000 feet on Dec. 12, 1953, a speed record at the time. It wasn't a perfect flight -- the aircraft encountered an inertial coupling phenomenon and went out of control. Yeager was able to recover it and return to the base. (Courtesy photo)
