The truth about 9/11

[Alt Thinker]

well...there is the association "Architects and Engineers for the 9 \11 Truth" who claims that the NIST reports are contradictory and scientifically absurd

3 wtc skyscrapers collapse on the very same day. This sounds a bit ridiculous.

then why didn't the Deutsche Bank skyscraper collapse too? It was much closer to the Twin Towers than the WTC7

One issue with all three WTC buildings was the use of framed tube structures to maximize open floor space by eliminating internal columns and structural walls. In this type of design load bearing columns are placed at the periphery and at the center. In addition to creating usable space this is good for resisting lateral loads such as wind. However in wide buildings if any support columns are compromised the opposite columns are now subjected to large moment arms. If they are compromised a chain reaction of failures can result.

In the Twin Towers peripheral columns were compromised by aircraft impact. Core columns now experienced large loads. These core columns were subjected to intense heat from the burning of 20,000 gallons of jet fuel. As each column lost structural strength nearby columns and opposite columns took on greater loads. When the core columns could no longer remain upright and the building tilted the peripheral columns failed completely and the building collapsed.

Number 7 was hit by debris and caught fire. Due to a poor fire suppression design coupled with negligible water pressure the fires went unchecked all day. The failure of number 7 was also facilitated by the frame tube structure design but in this case peripheral column failure resulted from floor I-beams expanding from the heat and pushing them outward.

Yeah, sure. All that *** could do was talk them to death.

Yeah! Plus, all the great scientific minds that claim we were all created 6,000 years ago by a magic wizard and every single species on earth lived withing walking distance of Noah's place! How can they all be ignored?

okay...let's talk about the WTC7. Are you saying that fires can cause the collapse of these steel skyscrapers? then they shouldn't build skyscrapers like that any more.
but...wait a minute. The new WTC7 has exactly the same structure.:sarcastic

I'm sorry. This is pure fantasy. I-beams expanding from the heat. No offense...this sounds like Science Fiction.
All the steel skyscrapers which caught fire and did not collapse.

let's leave the causes of collapse aside. the symmetrical collapse of a building is impossible.
A partial or\and gradual collapse would have been more believable

Have you ever seen the implosion of a building? It's completely possible, and slightly humdrum.

Impossible would be hiding the volume of explosives required to drop the towers without someone noticing, and then faking the aircraft strikes.

Did I say that they used explosives? I didn't.
But certainly they used something very discrete and powerful. Someone talked about nanothermites.

I didn't say that the aircraft strikes were faked, either.
But that doesn't exclude that the Twin Towers were demolished through other means. Other than two planes.

So, two aircraft hijacke dby terrorist slammed into the towers on the same day as this government plot coincidentally, but a building collapsing straight down is impossible. I am fruballing this just for how hard it made me laugh.

Susan Lindauer, ex CIA insider, has proved that the Government did know about the attacks. The Government did know that on that day all those planes would be hijacked. And all the rest.

by the way...I am not a conspirationist. I find absurd that three skyscrapers collapse in that way. From a scientific and rational point of view.

Two airplanes full of jet fuel crashing into buildings at 600mph would suffice as explosives IMHO.

Speaking from my engineering background, I don't find it absurd. It makes perfect sense from a physics point of view. Absurd isn't saying rain falls because of gravity, it's saying that it isn't wet. And Susan Lindauer spent time in a nut house after she went to jail for helping the Iraqis during the second Gulf War

Not impossible. There many many cases of the floor collapsing that way,

Modern buildings are structured like giant elevator shafts with each floor being an elevator. The top floor is constructed on the ground inside the structure and raised up to the top and held in place with dozens of welded brackets, all the rest of the floors the same way. So when the destroyed floor caused the floor above it came down on it, it was more than enough force to shear the Brackets and pancake all of the floors, one by one, all the way down to the ground floor.

I-beams will definitely expand if subjected to fire for most of a day. The fireproofing on them was only good for 2-3 hours. Why do you suppose they put fireproofing on steel beams if they would be impervious to heat?

The key is the framed tube structure. It gives lot of floor space compared to building footprint and is therefore cost effective in both real estate investment and construction cost. So it will continue to be used. With so many wooden houses burning down, why do they keep building them?

BTW the picture you showed is of a building with old style 'space wasting' internal columns.

What do you think happened and how do you think it was accomplished with no one noticing? Oh yes....and why?

Get me the forensic document from an expert witness that proves that Susan Lindauer is a mental person.

 

[Twilight Hue]

Pfffttt! It was giant lasers from outer space personally aimed by Bush, Cheney, and Satan.

True but Cheney has a gun.

 

[Estro Felino]

I don't know what happened. What I am sure about is that a symmetrical collapse is unnatural.
Besides...your point is contradictory. If you say that it is sufficient that a steel pillar falls down to provoke the progressive collapse of the entire building, it was sufficient to put a tiny explosive in that pillar.
With no one noticing.

why? I don't know. I don't have the crystal ball.

Yes, the public, the courts, and the government that was out to get her all say she's nuts, but you've got an inside line. My giant laser from space joke probably makes sense to her.

If the US Government planned all this, and they can't keep it secret from a head case (assuming the CIA has no security checks as an opener), wouldn't it make sense that Putin and China know too? And wouldn't they have used it by now to discredit the US? Or is every single government on earth except Norway in on it because the saucer people told them to be?

See if Mz. Lindauer has a spare tinfoil hat you can borrow before they get you, too.
