"These fires surely weakened any metal that was in the building, especially the primary truss for its open lobby design."
This is simply not true.
Talk to a construction engineer about the quality of metal used in tall building core structure, and fires.
If I am to question the zeitgeist movie (which is not entirely true) I also have to question this guy, why is he doing this in the first place?
"Just like the Twin Towers, there are not many ways tall, large buildings can fall, except directly down." This is to avoid what the movie maker concludes about building 7, that it was brought down by explosives.
"The film goes on to claim that in the 9/11 Commission report, building seven is "not mention[ed] at all". I guess they assume (probably correctly) that the viewer did not actually read it. I, however, have read it and I remember reading various things about building seven. Unfortunately for them, it is mentioned on pages 301, 310, 319, and 322 (twice)"
Then why does he not quote what it says? If it's that important and dismiss any doubt as to why the building came down.
I could go on... but don't care really. This guy, while some of it is true, is also lying. End conclusion is that you can't completely write off either of these guys. The important thing to remember though is, what is fact? Melting temperatures of steel is pretty much fact, is it not? Construction engineering is science, is it not?
I tend to believe the construction engineer when he says that the structure they designed could withstand several airline crashes without collapsing.
