Chaps,
This thread is getting so very tortuos.
I have said before that there are only two people alive who know with "absolutely no doubt whatsoever" what happened on that fateful day: Wratten and Day.
There are many people on this thread who believe/think/surmise/postulate etc, etc about possible influencing events ranging from extra-terrestial infulences to a bee sting and, of course, including airworthiness. All such theorising is a total irrelevancy in this case. I, too, have my theory - but that is also irrelevant, only fact is relevant.
Is there anyone out there who will categorically state on this thread that they know, with absolutely no doubt whatsoever, what happened that day?
If so, could they please make the statement and, more importantly back it up with fact and not supposition?
