The Douglas A-1 Skyraider "Lieutenant" taxis out at a commemorative warbird event, its propeller a blur of motion and underwing pylons loaded with drop tanks and ordnance-shaped stores. Known to its crews as the "Spad," the A-1 was prized during the Vietnam War for its ability to carry a heavy weapons load and loiter over the battlefield far longer than jet aircraft, making it indispensable for close air support and combat rescue escort missions.
