Yeager was the first man to break the sound barrier on October 14, 1947, flying the experimental Bell X-1 at Mach 1 at an altitude of 13,700 m (45,000 ft). Although Scott Crossfield was the first man to fly faster than Mach 2 in 1953, Yeager shortly thereafter exceeded Mach 2.4. He later commanded fighter squadrons and wings in Germany and in Southeast Asia during the Vietnam War, and in recognition of the outstanding performance ratings of those units he then was promoted to brigadier general. Yeager's flying career spans more than sixty years and has taken him to every corner of the globe, even into the Soviet Union during the height of the Cold War.
