This is what it looked (and, more important, SOUNDED) like when the towers collapsed... Note that the collapse starts above the 90th floor... right where the plane hit... also note that THERE ARE NO explosions... You DO NOT hear the sequential explosions which are THE ONLY way to control a deliberate demolition of a tall building...
also note that the collapse begins right where the damage and fire is... EXPLOSIVES WILL NOT SURVIVE THIS FIRE... they simply become part of the fuel load.
This is what it looks (and again, SOUJNDS like when explosives are used to bring down a tall building within it's own footprint... Note that immediately after the start of the collapse, THE ENTIRE STRUCTURE is shrouded in dust and smoke.
Why is that important? Because there are explosive placed on EVERY floor, with the ones in the center of the building set to go off first, followed by those towards the outside of the building. This causes the building to collapse inward, resulting in it's falling within it's footprint. It requires months of planning, prep work (removing components of the building, drilling holes into the concrete, running wiring, placing explosives. It is loud, messy, intrusive work. As demonstrated by the 1991 basement bombing of the WTC, you can't simply park an explosive and get the result above.
You're going to believe what you want... fantasy.
