Medic Kevin McPadden rushed to the World Trade Center to help save lives on 9/11… Here is his account of what he witnessed at WTC Building 7.

7 World Trade Center (7 WTC, WTC-7, or Tower 7), colloquially known as Building 7, was an office building constructed as part of the original World Trade Center Complex in Lower Manhattan, New York City. It was destroyed during the September 11 attacks.

Kevin McPadden, 9-11 First Responder
A former Air Force medic, McPadden was stationed just north of WTC-7 just before it fell, and actually heard the demolition countdown and explosions as the building started to fall.

Later in the segment Richard Gage discusses the WTC-7 and twin tower collapses as controlled demolitions.
