The all-jet powered Messerschmitt Me-262 Schwalbe (“Swallow”) prototype makes its first flight at Leipheim, Germany. (A piston-engine powered version had been flown the previous year). The Me-262 is the world’s first jet to enter operational service. In just over a month in 1944, Jagdverband a squadron hand assembled by Gen. Adolf Galland, the Luftwaffe’s chief of fighters, shoots down 45 Allied bombers.
Air Force Gen. Alexus G. Grynkewich assumed command of U.S. European Command on July 1, taking over the key assignment as the U.S. and its allies contend with a resurgent Russia and a grinding war in Ukraine.
