Disclaimer: I have no experience of airliner crashes at all.
But, it strikes me as slightly strange if this was CFIT and the aircraft impacted a virtually sheer cliff at normal cruise speed that, according to a number of comments, there are pieces of wreckage large enough to be mistaken for the aircraft 'breaking in two'.
Surely if it impacted a cliff as above it would be such an intense impact it would virtually disentigrate?
