A B-1 Lancer flies over Langley Air Force Base, Va., following a 95th Anniversary Maj. Gen. William “Billy” Mitchell memorial reenactment, July 22, 2016. Pilots flying 8 different airframes dropped more than 30 inert munitions to memorialize the bombing of the Ostfriesland, an “unsinkable” captured German battleship, during the 1921 airpower trials – an accomplishment which proved aviation’s place in the U.S. military.
