Improbable Collapse: The Demolition of Our Republic

On September 11th, the World Trade Center Twin Towers disintegrated like deliberately calculated, precision demolitions. But did you know that a third skyscraper also collapsed later that day at 5:20 p.m.?
The 47-story WTC 7 completely collapsed within 70 feet of its footprint (according to FEMA) in about 6.6 seconds.
These three WTC buildings became the first steel frame structures to ever totally collapse from fire and damage.
In the case of the Twin Towers, underground fires burned for 100 days despite firefighters pumping millions of gallons of river water onto the “pile.”
After many years, government investigators (working for NIST) concluded that Building 7’s rapid and dramatic collapse was the result of office fires. The official reports never mention molten metal. Not once did any of the investigators see molten metal.
We challenge the official reports and findings with facts that point to a more plausible explanation; that pre-planned controlled demolitions brought these buildings down.
Did the steel weaken rapidly enough from office fires to go into near free fall in the case of WTC 7?
How did the Towers turn into a blanket of dust that covered lower Manhattan while having the mass to destroy the remaining steel support columns that formed the central core of both buildings?
