North Tower Exploding by David Chandler

That was a superb analysis. The video repeating is the only way you can process the evidence into a believable script of the event. It's always been hard to sustain my "belief" in the demolition and coverups because it was so well executed. One of the problems has been the 'quality' of the destruction such that it makes it look like a collapse. It had to have been tested extensively on models beforehand. It is hard to believe human beings calmly, patiently researched and tested the technology and design of the demolition so they could instruct the crews who installed the explosives very precisely. All that evil intent, sustained over months-or more likely-years, and by so many, under strictest secrecy, leading to a perfectly executed military operation.

I have been reading Byron Katie's book: Change your Thinking, Change the World. It's pretty damned awesome. It's about clearing your mind of the stories you tell yourself about every little thing that happens, because these stories make us suffer. Then you do stupid stuff...One thing she got me to understand is that when people do crappy stuff and even heiness acts-no matter how horrible-they are innocent. Completely. People do what they do because they think they MUST. That it is the best course of action. So people who would take these actions, did so because they felt it was for the best. Dick Cheney is the way he is because he believes some story that guides him to do horrible things. Hitler was innocent. I'm not saying they shouldn't face consequences of course.  I guess that is how I try to understand 'evil' because otherwise it's just plain insanity and clearly, Cheney isn't insane in the commonly understood definition of the word. He is doing something that appears to be crazy but there are motives at work unobserved, that make him justify his murderering thousands of people in the towers and many many thousands more in wars for profit. ---OK, so these many people who prepped the towers for demolition, who did the science and design work, who created psyop diversions etc etc thought what they were doing was for the best. Oy! That's crazy!

This is the best evidence I've seen on what caused the collapse of the Twin Towers and Building 7:

best I've seen to date is a combination of Dr. Judy Wood's ideas and the Barometric Bomb signature.  Dr. Wood points to the "lathering up" of the towers just prior to global collapse.  She relates to some form of directed energy weapon.  This fits the barometric bomb signature perfectly - the lathering up creates the required field for detonation that disintegrates everything at the molecular level, including the steel columns, or what Wood calls "dustifies".

This would be required because if they dropped those towers without displacing all that mass, it would have severely damaged the retaining walls in "the tub" the lower levels and caused one hell of a flooding of Manhattan.  The use of the Barometric Bomb would also make relatively light and quick work of any prep work required prior to pulling of the structures.  Building 7 revealed a much more conventional demolition...

The barometric bomb was most likely used in the Oklahoma bombing and retaliatory bombing in Beirut many years ago...
