An A-1 Skyraider attack aircraft flies low over a South Vietnamese coastal beach and dune system, photographed air-to-air from an accompanying aircraft's cockpit. The rugged, propeller-driven Skyraider — nicknamed "Spad" and flown in the search-and-rescue escort role as "Sandy" — was prized during the Vietnam War for its heavy ordnance load, long loiter time, and durability under ground fire.
