The Secret of Flight (1959)

A lecture series about the basic problems of flight, explained by visual presentation of flow experiments. As the material of the lectures should be understood by every interested listener, no mathematical or other theoretical knowledge is used for explanation. Every problem is demonstrated by a true-life experiment and purely scientific language is avoided. Each of the lectures deals with a basic problem of flight. The experiments are mostly shown as flow picture but at certain points scale models and flying models are used to ensure easier understanding.
