In 1938, Liberty magazine sponsored a contest for a spirited, enduring musical composition to become the official Army Air Corps song. Of 757 scores submitted, Robert Crawford’s was selected by a committee of Air Force wives. The song was officially introduced at the Cleveland Air Races on September 2, 1939. Fittingly, Crawford sang in its first public performance.
The first page of the score, which Crawford submitted to the selection committee in July 1939, was carried to the surface of the moon on July 30, 1971 aboard the Apollo 15 "Falcon" lunar module by Colonel David R. Scott and Lieutenant Colonel James B. Irwin.
