He becomes chief of the U.S. Army Air Corps (1938–1941), commanding general of the U.S. Army Air Forces during World War II, the only USAF general to hold five-star rank and the only person to hold a five-star rank in two different U.S. military services.

1935 – U.S. Coast Guard Lieutenant Richard L. Burke sets a world seaplane speed record carrying a 1,102-lb. load over a 62-mile course at an average speed of 174 mph in a Grumman JF-2 Duck (shown above).

1997 – Third U.S. Air Force Academy Slingsby T-3A Firefly crash in 28 months kills a student and his instructor; although the Academy continues to fly the type, another incident in which the T-3 engine quits in-flight – forcing a dead-stick landing at the airfield – finally leads to USAF to ground the design in July. The fleet is eventually scrapped.
