Same as catalog # 515008 At Langley Field, engineers unveil a flying model of a unique vertical-rising aircraft, with wings like a four-slat Venetian blind, a new type of aircraft they may revolutionize air transport-and air war. MCUS - Engineer sitting on the floor with control box. Camera pans - Venetian blind with little propellers. MCUS - The model of the Venetian blind starts to move straight up. MCUS - Once the Venetian blind is air born it the wings un-curve and the craft picks up foreword speed. MCUS - Craft coming down and lands. (It's a remote control proto type that will never be built to full size).
