So what. I have heard with my own ears the recording of the emergency band radios with the fire chief asking, "Shall we pull it?"... and another voice responded "Yes pull it now!". WTC 7 then fell in its footprint.

Obviously the authorities knew what they were doing and are far more qualified than you or I in dealing with a disaster scene.

There is nothing wrong with yearning for the truth but demanding the truth at all costs, is costly.
