Examining the history of vertical flight, the program begins with the early helicopters, and then deals the with the pivotal breakthrough of the Cierva Rotor-head, followed by an explanation by the modern master of the Autogyro, Ken Wallis accompanied by the last movement of Bach's 3rd Brandenburg Concerto. Thereafter we move forward to Igor Sikorsky's helicopter, with interview with the great designer at the time of its development. Thereafter the focus moves then to the two great periods of helicopter lifesaving, the Korean War and Vietnam, where the helicopter truly went to war and heroes were made. The calm recollections of several very decorated veterans of the conflict make for compelling viewing, combined with previously unseen film footage of the conflict.
