Auto-rotary craft
Trying to outline design an auto-totary craft concept, was saddened to be reminded of poor safety record in fairly recent years though a little better more recently; the thread is most helpful in identifying main causes especially coincidence between both statistical and inherent causes thank posts for technical explanations. Yet I believe that when oiriginal Cierva autogiros and derivatives were conceived and developed throughout the 1930's they had better safety record than GA then. It had all been about avoiding fixed wing stall, before powered autogyros became helicopters.
