“
Dustoff” is the iconic call sign for U.S. Army air ambulance (MEDEVAC) missions, originating in 1963 during the Vietnam War with the 57th Medical Detachment. It was inspired by the dust clouds raised by helicopters landing to evacuate wounded soldiers. The term became legendary through Major Charles L. Kelly, who embodied its life-saving mission. Today, “Dustoff” still refers to rapid medical evacuation, now typically carried out by HH-60M Black Hawk helicopters, maintaining the same purpose and legacy.
