A U.S. Air Force A-1 Skyraider, tail code "TC," sits on the flight line with engine running and ordnance loaded for a combat sortie. Rugged and heavily armed, the propeller-driven Skyraider served Air Commando and Special Operations squadrons throughout the Vietnam War, prized for its long loiter time, heavy weapons load, and ability to survive battle damage while providing close air support and rescue escort for downed aircrew.
