'Shit! I've been hit!' Captain Bevan Smith's inadvertent broadcast alerted the troops on the ground that a Viet Cong ambush had been triggered. The knuckles had been shot out of his left hand. Somehow he got the Sioux chopper and battalion commander Lieutenant Colonel Alec Preece down safely, but his war in Vietnam was over. The story of Australian Army Aviation in South Vietnam begs to be told. The fledgling 161 Recce Flight deployed to Bien Hoa in 1965 and its Possum callsign was heard in the crowded skies until Australian operations ceased in 1972. The Flight's pilots flew more than 87,000 sorties to provide intelligence on enemy movements and locations as well as direct operational and administrative support for all task force operations. Three pilots were killed in action. Others were decorated for acts of quiet courage. Support and maintenance staff worked day and night to sustain the massive flying effort required. Author Peter Nolan has drawn on official histories and the Flight's records, supplemented by oral histories from its past members, to present a vivid account of the challenges faced and overcome by a small group of Australians at war. Written for all aviation enthusiasts, it is a timeless story of dedication, humour and courage under fire.
