A restored Republic P-47 Thunderbolt, nicknamed 'Lieutenant America,' displayed at a Tennessee Museum of Aviation air show. The P-47 was one of the most heavily produced American fighters of World War II, prized for its rugged airframe and powerful radial engine. Museum volunteers perform routine inspections to keep such aircraft flightworthy for public air shows, preserving the legacy of the pilots and ground crews who operated these fighters in combat.
