It wasn't just Building 7 that fell at free fall acceleration
'The North Tower of the World Trade Center was 1,368 feet (417 meters) tall, and the South Tower was 1,362 feet (415.1 meters) tall. Both towers had 110 floors'
Lets go with 1360 feet.
How long would it take a bowling ball to fall 1360 feet with no wind resistance?
'It is calculated that approximately 9.19 seconds are taken for a bowling ball to fall 1360 feet assuming no air resistance.' Google AI
It would take a bowling ball 9.19 seconds to fall 1360 feet with no wind resistance.
How long did it take the South Tower to fall?
'The World Trade Center's South Tower (WTC 2) collapsed 56 minutes after being struck by United Airlines Flight 175 at 9:03 a.m. on September 11, 2001, falling at approximately 9:59 a.m. The entire collapse process for the South Tower took only about 10 seconds' Google AI
It took the South Tower exactly 0.8 seconds more that free fall acceleration to collapse all 110 floors of steel and concrete into a pile at Ground Zero.
How about the North Tower?
'The North Tower (WTC 1) collapsed approximately 1 hour and 42 minutes after American Airlines Flight 11 struck it, specifically at 10:28 a.m. EST on September 11, 2001, though the complete collapse of the tower took only about 10 to 13 seconds' Google AI
All three buildings on Sept. 11th 2001 that displayed signs of controlled demolition and supposedly collapsed primarily due to office fires (first and last time ever) fell at either pure free fall acceleration (Building 7) or damn near free fall acceleration (Buildings 1 and 2) which is impossible for steel and concrete buildings.
The official working theory of the mechanics of the collapse of the Twin Towers is the 'crush down crush up' theory which states the upper section of the towers broke free and crushed each floor underneath it as it fell to the ground then the impact with the ground 'crushed up' the upper segment, leaving total destruction of the towers.
But this theory doesn't hold up to physics as it depends on resistance being provided by the impacts of each floor as the upper section slammed into them, busting them up and pulverizing the trusses (impossible)
In short, free fall acceleration means the buildings fell as if there was NO RESISTANCE AT ALL.
The official story depends on a GREAT DEAL OF RESISTANCE being provided by the floors below being struck and destroyed.
We are expected to believe the massive structure below the upper sections which held the upper sections in place for decades provided absolutely no resistance to the acceleration upper sections as they crashed together?
That is an absurd assertion from NIST and is physically impossible, defying the laws of physics.
Why would the scientists at NIST make such a ridiculously ignorant claim?
Why indeed.
