Re: Casulty numbers don't add up
250 people on one floor of something the size of the World Trade Center, with each tower over 200 feet on a side, is not an unusual number. It adds up to a room about 18 feet square for each person. I believe a large number of people managed to evacuate the buildings after the first hit, and maybe even after the second, before the collapses. I have seen interviews with a number of people who walked down 90 floors of stairs and left, apparently with little hassle. Let's hope for the best.
Certainly there is no evidence that a full 50,000 people died.
