A single-engine A-1 Skyraider taxis past U.S. Air Force ground support vehicles, including a crash/fire rescue truck and pickup, while ground crew tend to the aircraft. Rugged and heavily armed despite its propeller-driven, World War II-era design lineage, the Skyraider remained a mainstay of close air support and search-and-rescue escort ("Sandy") missions throughout the Vietnam War.
