You assume the route between penultimate position and ultimate position to be a straight line, that is not at all known. If there were other course "changes" between the last two points, the speed could be a great deal higher. IMO
Not the case at all. I was responding to a point made by Hyperveloce, and it involved the speeds he had deduced, ie. time v distances. The times were the mute point. Your point of course is valid!
You will remember that I have previously said that we know nothing about the 0210 Last Known Position - AF and the BEA know a lot more. When or if a deviation occurred and all the other facts that go to make up that 3D position have been with-held.
I am more inclined to believe it happened as a result of an upset - but even that is speculation.
