Grizzled....
Thanks for your reply. I thought the source was reputable enough, it's a very well regarded and generally well-researched series (Air Crash Investigation). The fact someone put it up on youtube shouldn't lessen it's reputation. But granted, it may not contain the amount of detail that the full report does.
I should probably not have said anything until more solid info becomes available, and I apologise for the conjecture. That said, I'm sure you can see where I was coming from.
