1940's Republic P-47N Thunderbolt. Thunderbolt flies its first combat mission a sweep over the Pacific. Used as both a high-altitude escort fighter and a low-level fighter-bomber, the P-47 quickly gained a reputation for ruggedness. Its sturdy construction and air-cooled radial engine enabled the Thunderbolt to absorb severe battle damage and keep flying. (U.S. Air Force photo)
