AAS Lt. James H. “Jimmy” Doolittle, flying a deHavilland DH-4B, takes off from Pablo Beach, Fla., and lands at Rockwell Field, San Diego, 21 hours and 20 minutes later, marking the first flight across the US in a single day. Doolittle only makes one refueling stop (at Kelly Field, Tex.) during the 2,163-mile trip.
The Air Force plans to add external weapons pylons on the B-1B bomber, both to increase the number of aircraft that can test hypersonic missiles and expand the Lancer’s loadout as USAF transitions to the B-21 bomber.
