At the beginning of this tread it says "hydraulic failure" and if i recall properly the Cobra has the same head and blades and some other components and I assume the same kind of hydraulic systems the B214B and the B214ST have.
If you lose both hyd systems in those aircrafts every controls seize, not much you can do except go where ever the aircraft is going at the time of the malfunction. That is probably why you don't see any reactions from the pilot in the last moment. There is nothing he can do.
