A Dornier DO 17, nicknamed the Flying Pencil, drops it's payload.

Bombs Away!

Three nurses talking with the Luftwaffe’s ace “Heinz” Bär (Oskar-Heinrich Bär nicknamed “Heinz”) and another German pilot at Comiso, Sicily, likely Summer 1942. Notice the rudder of the Bär’s airplane, the Messerschmitt Bf-109F WNr-13376, showing, with the number 100 (100th kill), the insignia of the "Ritterkreuz des Eisernen Kreuzes mit Eichenlaub und und Schwertern” (Knight's Cross with Oak Leaves and Swords) awarded precisely for the 100th victory. At the time of the photo “Heinz” Bär, which finished the war with 220 kills (221 or 222 according other sources), were, from 11 May 1942, the leader of the Stab I./JG 77 deployed in Sicily for the air offensive against Malta before the move to Tunisia.
