Ask yourself about the true star of this first years of the third millennium: the "thermite".
What are they hiding with that?
From the video: "Dr Judy Wood at the Breakthrough Energy Movement conference, 2012 Holland" [http://vimeo.com/57923364].
They should have evacuated for months those two towers in order to fill them with the sufficient explosive, from the ground to the impact level and multiplied for the perimeter of the towers, in order to obtain a (even) far away but similar special effect like the one they have got with discretion that September [and they should have stopped the traffic around the towers to allow trucks of "thermite" to unload their charge in front of the buildings].
