Good video. Many of these video's have dozen's if not hundreds of very telling anomalies before 911, on the day of 911, and in the ensuing investigation of 911. I find this evidence quite compelling. However, if a person really wants to get down to brass tacks, the official story is disproven in under 30 seconds. It is the total time of the collapse of 267 stories of buildings. 110, 110,and 47 stories. This is the most documented part of all the story.
N. Tower. It is impossible for 12-15 stories to smash 95 undamaged floors in North tower. Especially in about 10 seconds. It could be falling at terminal velocity and not drive the building to the ground, in any time, but to not decelerate. Ridiculous. Newton's 3rd Law.
S. Tower. It is impossible for the top section to smash it because of the same principle. But here we also have the 23 degree tilt of the upper block. There is no mass over an entire wall, maybe two, depending on angle.
Building 7. E=t+v. Once the potential energy is converted to kinetic energy for the first 110 feet, there is no potential energy to do any more work. i.e. bend steel, crush concrete, destroy 400 connections per second, melt steel, and send 40 mph pyroclastic dust clouds in all directions. There is very little potential energy for the remaining 4 seconds as well. Violates Newton's 1st, 2nd, 3rd, Laws of Cons. of Energy & cons. of momentum.
