This is such a joke! The falling building creates an accordian effect as the floors collapse and smash together causing air to be forced out any possible week point. The reason it imploded from top to bottom is because jet fuel burns at about 3000 degreese and steel melts well bellow that... so the steel beams became like rubber and collapsed on themselves. Everyone take note that this is an act of treason and an attempt to destroy our nation from the inside out!
