On April 18, 1942 sixteen B-25B Mitchell bombers launched from the aircraft carrier USS Hornet in a surprise attack on the Japanese mainland. Initially the bombers flew in groups of 2 to 4 but then flew singly at wave top level to avoid detection. The aircraft began arriving about noon over Tokyo and dropped special incendiary bombs. Although the raid caused little damage it achieved success in bringing the war to the Japanese home islands and boosted American morale after the devastating attack on Pearl Harbor. This print commemorates the 76th anniversary of the Doolittle Raid.
