When helicopter falls vertically, propellers, if free, will rotate and thereby take up energy of descent. It is calculated theoretically that such braking effect is probably insufficient to regulate descent within limits of safety. Experiments are suggested to investigate question further along lines which by theory alone cannot be fully investigated at present.
