Hey,
Here is a piece of undeniable visual evidence, that explosives were used on the Twin Towers...
In this video, you can clearly see that debris started shooting out of the sides of the towers before the upper mass even began to fall...

When watching this at normal speeds... I think what misleads our eyes... is the fact that the first ring of "material," appears to be smoke gushing out of the impact floors
after the upper mass begins to fall. But, when slowed down... what we find out is that this isn't smoke at all... but rather crushed concrete that is being ejected out the sides,
before the upper mass even begins to move.
NIST says that the kinetic energy released from the falling upper mass, is what contributed to the failure of the lower floors.... but, of course... we all know that kinetic energy is only present in a moving object, and thus... if the upper mass has yet to move... there is no kinetic energy... so what energy or force is crushing the concrete inside the tower, and then ejecting it out the sides?
And, please don't say the upper mass shot a laser out of its ass, because we've all heard that one before.
