Evidence of Demolition Charges In World Trade Center
'Before proceeding with this page let me explain a little something about explosives and how people perceive them.
I work in special effects. In films, great use is made of low velocity explosives such as untamped black powder and ANFO because they are low velocity explosives.
With a great whoosh and roar they belch forth with fire and smoke in a manner that has caused folks to drop their popcorn in matinees ever since sound came in.
Movies have conditioned people to expect a certain look and sound to explosions, all based on very low velocity explosives. In a stunning ironic twist, moviegoers seem to perceive the slower explosions as more powerful.'
