WOW, I don't know why you would bother to resurrect this topic. Between statements made using funny little symbols which mean nothing to average lay person and not describing the actions and reactions using plain English I don't think I have tried read this much dribble in a long time. If it was all in plain English then it just might be interesting as the Engineers that designed these engines obviously knew what they were doing at the time as they are still running today no matter how they have been mounted.
