A little off topic
Lone, I noticed this, "Alt 2 latched does not mean "flight control locked and no longer able to be moved."" before I noticed it was to bear and ignored the message.
I have an idle question that does not bear on this crash. Why might Alt 2 latch in and not be able to be escaped back to normal once the aircraft is flying normally again? Permanently latching out the aircraft safety systems for half of a long (10 hours?) flight seems counter productive.
