Lt. James H. “Jimmy” Doolittle, Doolittle made history as the first pilot to fly coast-to-coast in less than a day in a modified DeHavilland DH-4, in September 1922. Equipped with crude navigational instruments, he traveled from Pablo Beach, Fla., to San Diego, Calif., in 21 hours and 19 minutes. He made only one refueling stop at Kelly Field. The military gave him the Distinguished Flying Cross for this historic feat. (U.S. Air Force photo)
