It will be interesting to see what the hydraulic systems were doing at the time?
I've not been in the 135 simulator. What happens when both donkeys fail, how does it handle?

Surely you aren't thinking that the hydraulics are powered by the engines?
Perhaps a Fixed Wing pilot (where the hydraulics are powered by the engines)? To answer the question (giving him that benefit of the doubt) "it doesn't handle at all". Anything bigger than, say, an AS350 with an articulated or rigid head will lose all controllability with no hydraulics (that's why they have two or sometimes three systems for redundancy). I mean totally locked, rigid, controls.
