Blake777, thanks for the Antelope link, surely the most heartbreaking of all those posted so far and certainly most revealing of the search effort. Something I find mildly surprising is the extent to which the Egyptian government agreed, and so speedily, to large-scale Russian military participation in the sweep-up operation.
The men in the video were obviously combing for documentation and, possibly, remains, leaving behind anything not related to those two.
Given what looks like massive Russian deployment I'm wondering whether the presence of a large number of Russian military aircraft taking up space on the tarmac might have something to do with the turning away of "rescue" civil aircraft.
