"A measure of abnormal long put volume was also examined and seen to be at abnormally high levels in the days leading up to the attacks. Consequently, the paper concludes that there is evidence of unusual option market activity in the days leading up to September 11 that is consistent with investors trading on advance knowledge of the attacks".[67] —Allen M. Poteshman, The Journal of Business
Or that steel doesnt have to melt to lose its strength, and most buildings are built just strong enough to stayup. My response for "SQUIBS!/CONTROLLED DEMOLITION! THE COLUMNS LOOK LIKE THEY SHATTER!!" Is this. Find a hammer, now find a small rock or pebble, now hit it with the hammer really fucking hard. Looks like it exploded right? Now imagine the hammer is the top few floors of the building and the suppot columns for the building are your pebble. Its gonna look like the columns just explode,(they did) which then means there are no longer columns suppoting it and it just falls from there.
I also mention that it's really not that hard to believe that a building made in 70s New York (y'know, with all the mafia in the construction industry and rampant corruption) might not have been 100% up to code
EXACTLY this isnt a solid concrete bunker we are talking about, we are talking about just enough concrete to hold up a bunch of steel glass and paper in the air.
