BTW, the picture is of the North Tower, before it fell, and the video I mentioned is also of the North Tower, as it fell. I wonder if the picture by Biggert, which you mention, is, in fact, not a close-up the same explosions I saw? >>What you are seeing in this photo are large numbers of 12' sections of perimeter columns flying out ahead of the dust cloud in what is very clearly an explosive event. He got very close to the North Tower just before it fell, and captured some amazing pictures of its collapse and of the previous damage from the WTC-2 collapse. What is clear especially in Biggert's picture is that the building is turning to dust as or even before it falls. << Very interesting. My problem is that controlled demolition seems to be such an occult science and so little is written about it on the net, that I haven't any idea what should have been done to demolish the WTC towers if, in fact, it was decided to do so. In other words, what the correct technique would have been? What explosives? Where? How? If one knew what should have been done, then one could look for the tell-tale signs that it was done. But, what I can say, however, is, whoever did it, did a brilliant job. The buildings were brought down perfectly and I doubt whether there are many people in the world who could have done it as well. Indeed, I am sure that those in the industry must have a very good idea who was responsible.
