"453"^^ . . . "The Airco DH.2 was a single-seat biplane \"pusher\" aircraft which operated as a fighter during the First World War. It was the second pusher design by Geoffrey de Havilland for Airco, based on his earlier DH.1 two-seater. The DH.2 was the first effectively armed British single-seat fighter and enabled Royal Flying Corps (RFC) pilots to counter the \"Fokker Scourge\" that had given the Germans the advantage in the air in late 1915."@en . . . . .
