Two Douglas A-1 Skyraider attack aircraft cruise in loose formation above a solid cloud deck, photographed from a third Skyraider whose engine cowling is visible in the foreground. The lead aircraft carries the tail code "TT." Rugged and heavily armed, the A-1 Skyraider was flown extensively during the Vietnam War in close air support and combat search-and-rescue ("Sandy") missions, prized for its long loiter time and ability to absorb battle damage.
