USAF Capt. Hilliard A. Wilbanks, a forward air controller, resorts to firing an M16 rifle out the side window of his Cessna O-1 Bird Dog to cover the retreat of a South Vietnamese Ranger Battalion caught in an ambush near Dalat, South Vietnam. Severely wounded by ground fire, Wilbanks crashes in the battle area but is rescued by the Rangers. He dies while being evacuated to a hospital. Wilbanks is later posthumously awarded the Medal of Honor for his actions.
