The helicopter is the defining weapon of the Vietnam War. Used for a variety of missions--attacks, clandestine insertions, observation, rescues and evacuations, and more--choppers were everywhere in Vietnam and created some of the war's most iconic, enduring images, from the fictional "Ride of the Valkyries" in Apocalypse Now to the very real battle described in Hal Moore's bestselling book We Were Soldiers Once. Villalva dives deep into the archives to find the best shots of Hueys, Chinooks, Jolly Green Giants, and other birds, as well as the men who flew in them, to present the visual story of helicopters in the Vietnam War.
