I do not mind one bit your labeling me a Troll. I have been called much worse! Many times!
If you draw their track on a map, add in a few degrees of error from what ever source, pitch in slant/horizontal/vertical viz and a smattering of orographic cloud at the Mull and it seems fairly clear what probably happened.
To believe that some catastrophic event happened to the aircraft in VMC in the final seconds before impact seems a bit far fetched - to me.
We will never know - but what we do know is that the "Gross" finding is totally untenable - but the probability is that somewhere along the line a mistake was made in the cockpit. It will happen again, sadly.
As I said before:-
I quite thought that we were all "don't knows" but still can have firm opinions as to what probably happened. If it looks like a duck, sounds like a duck.....................and so on.
