Reply #2: the steel that's really missing is in the pieces

[szatmar666]

that contained the scientific data necessary to provide a mathematical model for the actual collapse sequence. all of the idiots posting here about "truthers" have no idea about engineering or what computer visualizations are all about. If they did they would question the fact that the structural steel was discarded before the official "pancake theory" was scientifically proven. Anybody who claims they know what happened is an intellectual lightweight or is jumping to conclusions for ideological reasons. No one KNOWS what actually happened because the evidence was discarded before anything of consequence could have been proven. AND THAT'S the SMOKING GUN!
