A Douglas A-1 Skyraider banks against an overcast sky during a warbird air show appearance. Developed in the 1940s and famously flown by U.S. Air Force and Navy pilots during the Vietnam War as a rugged close-air-support and combat search-and-rescue escort aircraft (call sign 'Sandy'), the Skyraider remains a favorite of air show and museum flying-collection audiences for its distinctive radial-engine profile and combat heritage.
