Airco DH.2
 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.
