NIST demise in freefall

NIST's demise at freefall speed

Question: If we cut both cables at the same time, which block will reach the ground first?

Answer: According to NIST, both blocks would reach the ground substantially at the same time. The healthy floors below the falling block on the left, according to NIST, didn't offer any particular resistance nor did they slow down in any way its path towards the ground.

As the 9/11 Truth Movement kept asking for clarifications, in September 2007 NIST answered: "We are unable to provide a full explanation of the total collapse." (Page 4, top par.)

In other words, NIST maintains that an event against the laws of physics took place, while being unable to explain how it could have happened.

NIST Finds Total Collapse Of Twin Towers From Gravity Alone Is Unexplainable

NIST Finds Global Collapse Of Twin Towers From Gravity Alone Is Unexplainable

Instead of trying to model the global collapse of two buildings through their greatest path of resistance at nearly free fall speeds via gravity alone, NIST simply surrendered the problem instead of relying on physics because it was too chaotic. The computer models were too complex apparently. In the field of structural engineering, nearly every problem has a solution except this one because of chaos.

However, physics will tell you that a item can not fall through other objects that provide resistance as if it were falling through air with zero resistance.
