*'Anybody throw some light upon this? Are there any AAIB investigators reading PPRuNe who could comment?"*
It is known that past contributors to this forum are known to the AAIB, some, very well connected. It is also known that they still read the posts here.
In answer to your question, my guess is that the AAIB have been alerted to this thread, if the are not already aware of it.
I doubt the busy folks at the AAIB would use this as a source as they would spend a lifetime parsing thru a mountain of **** to get anything worthwhile if at all. I assume they are well aware the primary skills and training/professions of the vast majority on here are totally unrelated to flying, I’d be kind of concerned if they looked to this forum for help in their investigation into this or any incident. That would be like requesting David Hasselholf’s judgment on an individual’s singing and acting capabilities, or dare I say it, seeking guidance on iceberg avoidance from the captain of the Titanic. Let’s face it, apart from extremely rare breed on here (that you can tell by their posts involving advanced scientific theories and formulas that go way over my wee heed) who are no doubt the Formula 1 drivers of aviation knowledge the rest of us are rank amateur weekend stock car drivers when it comes to aviation
