Engineering Video of the Twin Towers Collapse

https://ine.uaf.edu/wtc7 <---This is much newer news...but it's likely you didn't hear about this in the msm, circa 2019

Not the "Twin Towers Collapse"...

There were [3] three buildings that collapsed in total...

A very interesting study out of Alaska UAF, re: building 7, the 3rd of three building which collapsed that day

"The principal conclusion of our study is that fire did not cause the collapse of WTC 7 on 9/11, contrary to the conclusions of NIST and private engineering firms that studied the collapse. The secondary conclusion of our study is that the collapse of WTC 7 was a global failure involving the near-simultaneous failure of every column in the building."

In layman's terms...controlled demolition.

Things that make you go hmmm....
 
Great video, I guess I am not totally surprised with the analysis as far as the pancaking of floors gaining momentum as the collapsed. It was interesting with the soda can comparison, had not thought about the exterior pulling in.

As far as building 7, I'll let others speculate on that. ;)
