2,200 Architects and Engineers have all agreed that NIST's report of the reason for the collapse of world trade tower 7 is without merit. Tower 7 is the 42-story building that collapsed at near free fall speed, symmetrically, in its own footprint hours after the twin towers fell. It is the building that no one wants to talk about and rightly so because the implications are extreme.
NIST's official report is that office fires brought the skyscraper down and perfectly in its own footprint as not to disturb any surrounding building, AND nearly at the speed of gravity (no resistance to underlying structure support). Literally if you were staring at the building, turned to answer your mobile phone and say "hello, this is <your name here>, how may I help you", listened for a response and turned back toward the building, it would be nothing there. Plus you would see liquified molten steel and liquid concrete running at ground zero. DUE TO OFFICE FIRES.
Hear it for yourself.
