that an I-profile (or double-T in german) can be bent with "normal" demolition charges in this way the video shows.
really not.
double-T has more resistance than flat plates - much more.

either they have used extremly high power explosives or another technologie, not known to the public - i have no evidence - i know.

but why use charges, that bent steel in this way ?
has this ever happend in an normal controlled demolition ?
a lot of questions ...
;-)

This one didn't buckle. And it's curved beautifully.

Keep in mind the plates above were subject only to hand grenades. I maintain this column was subject to a massive shockwave -- what else?

To me it appears plausible that this column was where the core was severed further up in the towers (Remember the explosion in the North Tower when the second plane hit?), so that the caps rested on the perimeter only which was then weakened by thermite to initiate the collapse.
