BOAC,
I cannot DISagree with any of that! But it is completely at odds with the sentence I criticised in your previous post:
"The remains of the aircraft will 'fly' just as well in water as in air, and since most seem to be postulating some sort of rotating motion at impact there is no reason why this should not continue during the 4000m drop resulting in ANY sort of orientation."
Re your latest: would you prefer "track"? Not sure the difference is significant in this case.
