The Messerschmitt Bf-109a fighter prototype makes its first flight at Augsburg, Germany. More than 32,000 Bf-109s will be built (including post-war versions in Spain and Czechoslovakia) in a multitude of versions, making it the second most produced aircraft of all time. (Most produced: Ilyushin II-2; see entry for Dec. 30, 1939.)
REFORPAC, the large-scale exercise in the Pacific planned for summer 2025, will be on a scale unseen by the Air Force in recent memory: nearly 300 aircraft spread across 25 locations.
