The Secret of Flight - Season 1 Episode 1
Dr. Alexander Lippisch introduces his series and the basic laws of fluid motion by means of new methods of visualizing the flow phenomenon. He also introduces the Smoke Tunnel (a type of wind tunnel) which is so designed as to make it possible to observe the entire flow field and to see clearly the action of the aircraft components. He shows how the first man-made flying vehicle, the kite, is a primitive application of the dynamic lift of the flat plate.
