Re: They're almost done..
It's been two years. All of the relatives know their loved ones are dead. Time to move on.
They may "know" it (for some value of "know") but many don't believe it. Just look at some of the comments here on El Reg with all sorts of explanations for Apollo, plane crashes, 9/11,etc. People are conditioned in many places to needing to see the body. By now, I'm sure there's little that remains of the people on board that plane... but there are those that will insist.
