Hmm that video doesn't really proove anything though. The presenter was trying to silence him most of the time or that's how it looked to me.
The articles on that site seem to be convinced this building was blown up, they say no fire could cause that damage.
Are they not forgetting that over 1 million tonnes of steel and concrete just fell to the ground right next door? That's gotta be like having and earthquake happen in downtown NJ? Surely that would dammage the foundations, and aid the collapse.
And have they also forgotten that both the main towers were hit by a jumbo jet at a couple of hundred mph?
It just looks to me like they are looking for something they want to be true and ,making the evidence fit to their theory.
