I think that most of us who are "professional aviators" can tell the difference between informed speculation, and that which is complete twaddle, or perhaps someone seeking a sensationalist reaction which can then be reproduced as "authoritive comment", all because it originated from these erstwhile pages.
I'll freely admit that I was very anti pre AIB report speculation until last year, when a friend told me he'd read of speculative cause of a fatal C310 accident in the U.S.A , he checked his own identical model - only to find a similar fault, which was a major contributary cause to the original accident.
Of course I accept that the chances of this happening again are remote - but that doesn't matter if it helps someone in a similar situation.
