Structural damage from the falling debris of the towers.
This was really insufficient to bring it down afaik

The National Institute of Standards and Technology (NIST) concluded that the collapse was caused by uncontrolled fires fueled by office furnishings, which led to the failure of a critical interior column and initiated a progressive collapse. This was the first known instance of a tall building collapsing primarily due to fire.
"First known instance"... aka did not happen because they were built to withstand fires
was pretty much the sole proof this thing wasn't what we were told it was
building 7: not hit by plane, really no reason it would fall down
Let alone fall down at virtual freefall speed.

WTC7 was built differently and over another building like a spider. Not embedded straight down in the ground.
But YES we knew the attack was coming, maybe even helped them...

It was sufficient to damage the spider legs that supported the rest of the building and when they failed the building came down.
The spider legs were out to the edge of the building unlike normal building which have internal core supports that go into the ground.
This was distributed weight over another building... Completely unorthodox just to save money and keep the other building below.
40,000 tons of steel cant collapse with a few debris. 'nuff said.
Bad woke construction and failure because of a wall of debris did. Tho 'nuff said.
