AAC Lt. Albert Hegenberger (navigator) and Lt. Lester Maitland (pilot) make the first flight from the U.S. mainland to Hawaii. Flying a modified Fokker C-2 nicknamed Bird of Paradise, the duo leaves Oakland, Calif., travel 2,407 miles and arrive at Wheeler Field 25 hours and 50 minutes later. The flight is primarily a demonstration of the Army’s advances in navigation (and also to show up the Navy). Hegenberger and Maitland would later be awarded the Mackay Trophy for 1927.
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.
