WTC Collapse on 9/11/01

Yesterday I went to a lecture given in Lexington KY by one of the structural engineers who investigated the collapse of the World Trade Center. Gist of his presentation - it's a wonder that the buildings didn't collapse immediately instead of standing for an hour or two. You can find a preliminary study on the FEMA Website.

The more detailed follow-up study is not online yet but on 4/05/05 will be posted HERE by NIST.
