A Douglas A-1 Skyraider flies above a bank of tropical cumulus clouds during a mission over Vietnam, photographed air-to-air from a second Skyraider in the same flight. Rugged and heavily armed despite its propeller-driven, World War II-era design, the Skyraider remained a mainstay of American and South Vietnamese air power throughout the Vietnam War, prized for its long loiter time, heavy ordnance load, and ability to absorb battle damage.
