Don, I was not trying to be controversial, just merely stating an opinion. I have a reluctance to accept on face value those things which are not proven, just merely a theory.
I was fortunate to be on the team which applied electical power to the first DC-10, working closely with the engineers who desiged the system around Westinghouse's control boxes. Many of their theories were proven to be wrong and they were corrected on the go. These men were probably some of the finest Aviation Electrical Engineers of their time, but the system was far from flawless.
