So are you saying that the jet fuel deformed the steel beams which caused the bolted connections to fail and that releases the whole floor to fall straight down?
And that can happen with multiple floors simultaneously?
This invalidates the theory that states floors should have fallen progressively and progressing no faster than g?
Am I understanding that right?
I would like to put out there that I trust your science, but it only demonstrates that burning jet fuel could have produced a collapse like that. It does not prove that it did cause the collapse because other causes could produce the same result.
Do you have any thoughts on the footage of what looks like molten metal, possibly thermite, ejecting from the buildings immediately before collapse?
Or the photos of beams that appear to have been intentionally cut in a straight line by melting?

Progressive failure in structural engineering is typically the opposite of sudden failure, it means significant deformation had to happen before ultimate failure.
I mean it would be physically impossible to accelerate faster than a g during collapse unless there were outside forces present.

If the Government did 9-11 why didn't they fake WMDs in Iraq?

Not even Osama bin Laden/Al Qaeda thought the buildings would collapse and were shocked that they did.

and yes i know what you're implying, but that is stupid. They got what they wanted, no need to risk physically planting a fuking nuke

I think the thermite and cut beams were staged so we are talking about whether or not the twin towers were demolished and not talking about WTC7 not being hit by a plane but also collapsing.
Does the WTC7 collapse explanation also conform to your science?

Regardless of what happened that day, there's no way the patriot act and the egregious destruction of our civil liberties and privacy post 9/11 were not planned.

my dad actually helped build the twin towers and he said during construction they mixed saw dust in with the cement to save costs, he bet his worker buddy 10 bucks that it would fall under its own weight if a plain smooshed into it. He never got those 10 bucks from billy, probably because he died when it happened. make of that what you will.

I wanted to understand Statics, building systems, etc. This guy does a good job explaining the physics behind it. I love conspiracy theories, and i don't buy the official story, but i do not believe the building was rigged. There is so much that goes into rigging a building for demolition, i can't imagine it would go undetected. Building 7 is the more fishy story, especially with that being a huge office for the Feds. Also, Larry Silverstein is sketchy AF.
I also don't believe the towers were rigged.

It's funny how most people can't fathom that rich people at the top and the govt could do something so disgustingly evil for monetary gain. Just LOL. They think of us as plebian trash rather than equals (dfs)

just googled it its been pumped 1,800 feet vertically (but this was recent).

flight 93 being shot down instead of the hokey "lets roll" story

but that being said if you are willing to doubt any of the story, you have to doubt all of the story.

I've seen in pump magazines where they just have a pump feeding another pump, and so on all the way up the building.

the jews did 911
really got the goyim wanting to kill israel's enemies didn't it, look up the clean break memo written in 96 that was authored by the people that would later be staffed in bush's regime.
fact:9/11 would not have happened if Israel wasn't our greatest parasite erm i mean ally
