>>One coordinated visit with photos of all faces would do if the remains <<
That might be fine for unconnected analysts but that’s not the memory you want to leave with close relatives. I am sure their ride to the bottom was not smooth. Quite a few probably got the snot knocked out of them with overhead luggage slamming into them and so on and so on.
Yeah, many families might prefer to give the robot operators a photograph and tell them hey, look for this person and only if you’re pretty darn sure you have them then show it to me, or just go ahead and compare the DNA then tell me if you got a match.
But the same thing happens anywhere people died in carnage.
