Why don't you listen to what the man had to say instead of being sucked in by the corporate media?
As for the damage , I have worked in construction for over 20 years and I know well enough that uneven damage does not cause symmetrical collapse at freefall ...quite simple.

I have listen to him, and a few other ones like him. Still find it lacking. I too have worked in construction for 10 year, in structural engineering, and yes damange can cause a building to fall at free fall speeds. A certain criteria does need to be meet, but it was meet in WTC7.
