I'm going to add that the writer of your puff piece starts off with "The mechanics of the collapse are really much more simple than conspiracy theorists would like you to believe."
It's such an absurd statement when one considers that the World Trade Center's three buildings are the only steel structured high rises that have ever collapsed due to fire. Here are real fires that lasted much, much longer but they buildings did not collapse. http://investorshub.advfn.com/boards/read_msg.asp?message_id=20966549
