Hmmm...

You know, if someone had ventured the idea that a volcano à la Eyjafjallajökull had erupted right smack in the middle of New York on 9-11; I would have believed him/her on account of those pyroclastic flows following the streets...

On another hand, I may be totally off with that one and would need confirmation from architects and engineers but: there is that thing about modern highrises that don't get building permits unless they are built with an in-built demolition scheme... if that were the case for the twin towers, then that would explain the presence of nanothermite all over the place -- used and not used... also, that Silverstein guy forked out a down payment (never had to pay full price) for these towers despite the fact they were slated (legally per city law) for imminent demolition.

Oh well... my few $0.02...
