Renewed and Scientific Investigation into the Causes of the Collapses of the World Trade Center Twin Towers and WTC 7

Order a scientific investigation into the collapses of the WTC Twin Towers and the 47 story WTC 7, that occurred on 9/11/2001. There is evidence that suggests it is more likely the buildings were brought down by controlled demolition rather than structural damage caused by airplanes crashing into the buildings and the effects of fire weakening the structure. Evidence includes; explosive residue found in WTC dust; molten steel found in the rubble, jet fuel nor typical office contents can cause fires hot enough to melt steel; all three buildings came down at free fall speed, not slowed by the structure below. Chemist, physicist, building design professionals, and controlled demolition experts have examined all evidence. For more info, please view; http://video.pbs.org/video/2270078138
