sorry to all the hysterical type who want to believe in this hokum simple physic be all that need to explain the collapse . hold the explosive . ask yourself why the narrator ask an unending stream of question ( and not very good one ) . why . because this film contribute nothing and just dramatize cloud of fall debris ( which do hold a certain ghoulish fascination ) . why the tower fell and other serious documentary actually answer question and present fact and and contain 100 % less carmina burana . pause a moment to remember those who perish that day and work for justice and understanding and and peace in the world . what the world doesn not need be more groundless suspicion and fear and and hysteria .
