Based on where the planes hit, complete collapse is physically impossible without explosive help. (Conspiracy)

submitted ago by ScannerDarkly

For every action there is an EQUAL AND OPPOSITE reaction.

It is physically impossible for the much smaller upper portion of the building to be able to crush the much taller and stronger built bottom portion.

30 upper floors can only crush at most 30 lower floors. Even less if the 30 below have more steel reinforcement.

The only way the upper portion can do more damage is with explosive help.

You know our school system is fucked when no one bothers to question why the upper 30 floors were completely invulnerable to the crushing forces until they hit the ground.

Says another armchair engineer with no credentials.

Who just made the case that 60 floors of falling material would do less damage than 30 floors of material.

There are things to question about that day which are legit fucked but the sheer volume of retards spew8ng shit like this ensures that will never happen.

Everyone seems to want to pretend that these buildings weren't 30 years old, and weren't built by the lowest bidder. Amazing.
