9/11: 7 World Trade Center (WTC 7 Free Fall Collapse)

THOUSANDS OF ARCHITECTS and ENGINEERS concluded WTC Building 7 WAS CONTROLLED DEMOLITION. 

The government admits WTC 7 hit free fall, gravitational acceleration, during its collapse. They say it fell primarily due to fire, and that the interior of the building separated from the exterior walls. 

This footage of the Pentagon aired only once after 9/11. Who here can remember this?
