I can believe 7 was controlled. 1 and 2 were a steel donut design for the enforcing beams. The outer and central beams were sheared out and some on the opposing side were sheared as well. They weren't sheard at the top floor. They were sheared between the middle and the 3/4 way. This is important because people don't know just how large these buildings were. Length wise they were an entire block, I remember walking by them and thinking holy shit these are big buildings. That is just the length. Now, each of these buildings had 110! floors. That is one hundred and ten floors. The biggest buildings in most cities don't go over 40 stories. This means that if the planes sheared the outside iron girders around the 60th!!!! (step back and think about that for a second) floor, it would mean they had 50!!!!! floors of concrete and steel above them. Even if they sheard around 70th or 80th floors, that would still be 30 to 40 floors of concrete above the sheared iron girders. That is basically a whole normal building sitting on top of sheared iron girders, and of the girders that were left were engulfed in fire that could easily weaken steel just enough to fail. The physics of this are just undeniable. The videos of all of this and picture of the towers paint a false picture of just how massive the buildings were. Most people see pictures of the twin towers and think they are maybe a bit bigger than a standard 30 or 40 story building in a majour city. They don't comprehend that they were over twice the height and over twice the length / width of the average tower. The amount of work to secretely setup a controlled demolition of 1 and 2 is far more work than to allow a few israeli fanatics to drive planes into the buildings. Possible? Yes. Probable? Far more probable that 40 stories of GIANT CITY BLOCK SIZE FLOORS pancaked through the initial weakened iron girders in my opinion.
