Creative Speculation

What, no defense of your 'theory'?

This doesn't disprove that the initial squib was from a demolition charge.

Neither does it prove it. I still don't see how all those charges managed to go off when such a chaotic and completely un-modelable event happened. I mentioned un-modelable because no doubt somewhere someone has the theory that some TLA was able to determine exactly the damage the planes would do and plan the planting of the explosives and their detonators so they would be unaffected.

Explosives go off because another explosive starts it. Explosive power is because of brisance. If there were charges, the plane impacts should have set some off. It's even possible that ( I know very little about explosives) they might have initiated a pulse (I don't know the correct term) through the det cord and then triggered even more explosives.

As for the squibs, they are easily and realistically explained away as what happens when one acre of air is compressed and forced out the windows and every floor was an acre in size. That air had to go somewhere, yes?
