AFAIK the majority of helicopter crashes are not caused by a loss of engine power, but autorotation is relevant specifically in that context. It's not relevant to helicopters crashing into hills during storms, or hitting wires with the rotor, or anything like that. We're discussing what happens if the engine stops, not all accident scenarios. > Even if an autorotation is semi-pulled off it's likely to be a hard landing that causes significant injuries. Yes, but it's better than being dead.
