OHA Professor, I agree with your comments regarding the Safety Observer. But, with humans being humans, something is always bound to go wrong if the chance arises. All you need is a tool or a wire to slip(which can happen when it's pouring with rain) and you suddenly have a disaster on your hands. This extra Line Mechanic may be needed down below the Hydraulics on the EWP malfunction. As rare as this is, there is a first time for everything.
