A restored Douglas A-1 Skyraider — the rugged, propeller-driven attack aircraft flown by 'Sandy' pilots on search-and-rescue missions during the Vietnam War — sits chocked on the ramp at Gatlinburg-Pigeon Forge Airport, Tennessee. Aircraft like this one are lovingly maintained by aviation preservation groups and flown to veteran reunions to honor the pilots and crews who flew them in combat. Project: 219506
