The practical information on the DVD I though was pretty good and the production value shows. But I though the explantion of the aerodynamics and the forces involved in an autorotation was incomplete.
I also saw on thing on the DVD that I though didn't fit. In the 180 auto chapter there is a quick clip of the pilot doing a piroette down a taxiway at about 10-12 ft off the ground. What purpose does that serve on a DVD about autorotation?
