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.)
Anduril and General Atomics will develop their Collaborative Combat Aircraft for the Air Force, beating out Boeing, Lockheed Martin, and Northrop Grumman, the service announced on April 24. But any of the non-selected companies can compete to actually manufacture the eventual design, the Air Force said.
