not saying i believe this but rumor say explosives were in the basement,conspiracy act.ï»¿ If you watch a video in super slow motion you can notice SMALL but visible flashes on the lower floors as the 2nd plane hits the tower. I PERSONALLY do NOT believe this so do not get hissy at me. Other people who believe in the conspiracy theory also talk about the Jets being Overfueled for the journey(morefuel=moreweight)planes arnt fueld maximum)more fuel=more devestation. sorry
