I'm afraid my experience, fortunately or unfortunately, is not directly in the field of air accident investigation.
The principles, though, are the same.
While I've not had the time to examine the available material in minute detail, I do think, from reading the contributions to this thread,
that I've a fair grasp of what went on that fateful day.
I therefore defer to the observations, knowledge and experience of those who've had the practical experience in that particular field.
Once again, good luck and please take on board what I said earlier.
