Thanks for the info on the Chinook crash. I wasn't on the mission but our CH113 (Canadian Forces BV107) was the helicopter on scene for the rescue (wasn't possible).
We were all very interested in why this crashed. Similiar flight control systems in the two helicopters.
For Lu, I assume that the "autorotations must be entered sideways" was a joke. Although fore and aft cyclic works differently than in tail rotor helicopters, it works the same from a practical point of view. Including autorotation.
