A look at tests on early helicopters including one in flight.
No title on the film.
Shots of very large propellors going slowly round on early aircraft. We see a man pulling a lever and turning a wheel on them. L/S of four fast propellors, the early helicopter takes off and hovers above the ground. Some men run out of the way.
