A U.S. Air Force A-1 Skyraider is towed across the flight line during the Vietnam War. Nicknamed the 'Spad' for its propeller-driven, World War II-era design, the A-1 remained in frontline service into the late 1960s and early 1970s, prized for its heavy ordnance load, long loiter time, and rugged survivability in close air support and search-and-rescue escort ('Sandy') missions.
