I don't understand dutch, it may as well be double dutch to me, but someone mentioned 'hydraulic' when the occupants were being extracted from the wreck. Even so when I learned on the Bell 47 the instructor would regularly pull up the hydraulic off handle and I would have to fly it without hydraulics. The Robinson could easily be flown without hydraulics - with the correct training.
It just looked like it was going too fast and probably downwind as well to me.
