The North American Aviation P-51 is the celebrated, American long-rage, single-set, World War II, fighter aircraft. Designed and built in just 117 days, the "Mustang" first flew in Royal Air Force (RAF) service as a fighter-bomber and reconnaissance aircraft. They were later converted to bomber escorts, and employed in raids over Germany, helping ensure Allied air superiority from early 1944. In this role, the Mustang was the first fighter/escort possessing the capability of accompanying our Bombers all the way to targets over Germany. It was reported when this was witnessed by Hitler, he said "the war is over" and indeed, this was the case. Along with being a major element of Allied Air Forces in Europe, the P-51 also saw service against the Japanese in the Pacific.
