[quote name='Koggit']but.. wait, wut?
what are you saying?
you don't believe fire can cause a building to collapse?
skepticism's great and all, really (see #47 for acceptable skepticism).. but there's a limit..[/QUOTE]
I agree with FOC, wtc 7 is the single biggest mystery of all of 9/11.
First of all, there is more evidence that a thermite like stubstance was used in it's collapse than there is for a regular fire.
Second of all, do you know how many buildings, in all of recorded history, have 100% collapsed due to just fire? Look it up, because you are certainly not going to believe me if I tell you.
Now, it's arguable that the twin towers fell due to other factors other than just fire, like impact, or their non-standard height. But WTC 7 was a very standard building.
Again, I am not trying to say it was an inside job. Given the sensitive departments that were contained in WTC7 it's not entirely wacko to think the building was rigged with a sort of 'self destruct' in the case of an emergency (like being ablaze). But that's just one theory.
