it's time to shut down the 9/11 LIE movement, join me on my you tube channel loosechangeexposed to see more videos and join in on the dabate.<br />here is a fact that truthers never tell you, the dust clouds at the WTC created by the towers collapses were not from the concrete being blown apart by planted explosives like they want you to believe, sure the concrete was smashed into many small pieces by the vibration from the pancake and pile driver effects, and when you look at videos and pics of the demolition debris field you can see that most of the concrete did not turn to dust, there was 4,400,000 square feet in each tower above ground level, mainly office space, the interiors were finished which materials included sheetrock, it was the sheet rock which created most of the dust clouds when the towers collapsed not the concrete.
