From an engineer's standpoint, I can prove that these buildings did not fall just like that because of a fire... Anyone who knows the properties of these buildings knows that Al-Qa'ida didn't do it. These buildings were blown up from within...

This moron lost me at this point - any sort of rational conversation with someone like this is not possible.

This is the mindset arrayed against us.

But they didnt collapse because of the fire, directly, anyways.

The fire caused the beams above to fail, bringing them down. The excess weight from the upper beams was too great a load for the lower beams, causing that next lower section to fall, also.

That started a chain of events, with each successive layer of material falling on the next lower floor, hastening the collapse.

So, in reality, it was the overstressing of the floors that caused the collapse.

This idiot engineer ought to be made to write that 1,000,000 times on a blackboard, then ask him, "What caused the floors to be overloaded?"...and make him write THAT answer 1,000,000 times again...
