Lu, I understand your point of view but.....
The religious representatives you allude to are discussing concepts/philosophies. Accordingly, each is going to have a different answer, however I would wager that if you asked each to put his hand in boiling water, they would each report the same.....It's hot (although the expletives may differ somewhat)! Similarly, we are examining actual rotor dynamics, not philosophies about rotor dynamics, therefore there is likely to be one answer of fact, not many of different opinions. I go back to the question previously posted..have you asked yourself why universities, the Air Force acadamy and test pilot schools teach aerodynamic precession? Why would they merely teach "an opinion"?
The HUMS stuff would be good on the HUMS thread. Your post is a good read.
