Are you contesting the AAIB now with all your 12000 posts???? Take a holiday.
I did TC.....in the UK where I sat across from Nick Lappos when he received the Barnes Wallis Award at the GAPAN Banquet.
To refresh some memories of what has been discussed before......

TC.....until the AAIB issues a final report and definitively states exactly what they "think" caused the crash.....and it turns out to be VRS in their professional opinion......any categorical statement to that effect is premature.
Do tell us why you think IVRS would cause the Crash would you?
"Incipient" must mean something completely different in your English than it does in mine.
Lone,
The Army did a study in 1971 that was incorporated into Navy Training and has some effect upon the VRS limitations that apply to the Osprey yet today.....meaning the 20kts/800FPM ROD numbers.
TC,
You might chew on the information in this link a bit and see how it squares with your thoughts.
