On October 14, 1947, U.S. Air Force Captain Chuck Yeager became the first man to break the sound barrier, flying in a rocket-powered research aircraft. Yeager 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 was promoted to brigadier general. Yeager’s flying career spans more than 60 years and has taken him to every corner of the globe, including the Soviet Union during the height of the Cold War.
