Christoph Hoffmann, a professor of computer science and director of Purdue's Rosen Center for Advanced Computing, a division of Information Technology at Purdue, says the animation reveals more information than could be conveyed through a scientific simulation alone.

I don't care for conspiracys or the real story. Until I know real facts, all I know is:
WTC 1is hit by something
WTC 2 is hit by something
Pentagon is hit by something
WTC 2 collapsed
Something hit a field in Pennsylvania
WTC 1 collapsed
WTC 7 collapsed.

Very poor effort to explain how an Aluminium plane cuts those steel columns. This production is BS.

9 hours ago

Not "cut", bash. If you don't like the animation you can always read the FEA on which it was based, which is infinitely more detailed.

I could be wrong but I thought building was designed to have as few interior columns as possible. Something thing to do with a truss system that opened core of building up for better interior layouts.

@M Fitz
I see. Ty

47 central core columns, 220 outer perimeter columns joined together by long span floor trusses in the open office space.

Read the FEA then and if you have any concerns feel free to voice them. Make sure to show your math.

Since when can an airplane fly through a reinforced steel building!!

11 hours ago

Since about 1944 when much smaller, much lighter and much slower airplanes proved they could fly through steel hulled and armored warships,... and sink them. Learn your history.

I really thought I heard wtc was not built like this, that I was designed to have as few interior columns as possible, using some kind of truss system, making interior layouts more convenient. If you're interested look into it online. I remember there's a video of guy who designed building describe the open layout. I believe it's why building pancaked the way it did.

10 hours ago

It definitely could

10 hours ago

It just broke through steel beams?

12 hours ago

Hollow box section columns bolted together, not "beams" and yes, 115 tons moving at 466 mph has more energy than a ton of TNT. Stop thinking materials and think energy.

And what happened to the rest of the building???!!!!

Not the subject of this study.

This is total bullshit.
If anyone believes this is possibly an explanation try throwing a beer can at a block wall. Throw it as hard as you can.....now throw an egg at a glass coke bottle.....you will get the same results.
Planes did probably hit the buildings, but explosives were in fact used.
Too many eyewitness accounts immediately afterwards confirm this.
An aluminum substructure regardless of speed will not defeat materials of denser subatsnces.
How is tank armor defeated?
By firing a projectile much denser at a high rate of speed.
Anyone who believes this narrative is simple minded.

If anyone believes this is possibly an explanation try doing something completely non-analogous and irrelevant. Yeah, good plan.

This is hilarious🤣😂 people who believe this are mentally ill.. people who believe that an aluminum plane can fly through concrete and steel columns🤣 the plane should have smashed into pieces when it hit the concrete and fall down before entering the building at all.. let alone coming out with it's plastic/aluminum nose on the other side of the building.. especially the wing figure in the building is laughable.. besides the hundreds of arguments which point to a controlled demolition/false flag attack

1 day ago

@M Fitz do you claim that the outside of the twin towers was made of plastic or something or in what were the steel colums used? The outsidr of the tower has no concrete you say.. do you know how construction works btw?😂😂 you keep amusing mee.. you are funny ill gove you that😉 and good job on this act..

@M Fitz its quite funny that you velieve to know more about pgysics than actual scientists😂😂 coen vermeeren is a Dutch airplane engineer for example.. just join the public debate in the Netherlands if you dare woth that pathetic information and reasoning😂 its a FACT in the Netherlands that this was impossible with planes..you dont have to convince me.. only you need help with your cogbitive dissonance

@Nordin Thorsten - I can see reading comprehension is still not your strong suit. No wonder you have not figured out 9/11 after more than 17 years. Again, you said:


"people who believe that an aluminum plane can fly through concrete AND steel columns,...(emphasis added).


I correctly pointed out there was no concrete used in the COLUMNS. Just steel, no concrete. What part of that do you not grasp??????? Why is that so difficult for you?

4 hours ago

@M Fitz was there no concrete used in the twin towers or what are trying to tell?

Why is WTC 7 always overlooked? That building wasn't even mentioned in the official '9/11 Report'...

👀Why?

Because the official storey is BS.

@M Fitz <--- this is a sock puppet account.

1 day ago

It isn't overlooked, just not the subject of this study. If you would like to watch a study of the Building 7 collapse I can think of several good links. Also, there is no such thing as "the official 9/11 report". There are hundreds of reports from different sources covering different aspects. There is no one single master report that covers every single aspect in detail. None of them BTW cover St. Nicholas Church in much if any detail at all either but I don't see you complaining about that.

I'm talking with gentlemen or ladies, @MFits and @12weasel100، Which are commented on in people's comments,and sometimes Disrespectful to the people.
You play the role of fools, or you are really stupid.

It's not just about the animation or the way the building collapsed.(of course they did not collapsed, But they were peeled like bananas).
The main thing is that after this stupid show, thousands of American soldiers and citizens, and more than one Million of non-US citizens were murdered.
I invited you all wize and truth seekers folks, to see and hear Dr Judy Wood investigation on how the wtc disappeared!

At the angle the plane hit the building I doubt it was traveling at 600 mph, and why would the whole plane enter the building without a single piece of debris from the aircraft fall outside the building at point of impact, steel is harder then aluminum, I just don't think it's possible but I am not an engineer

1 day ago

The "official" impact velocity was 466 mph, not 600 mph although the mind boggles as to what angle the impact was at (straight and nearly dead level).
Lots of aircraft debris was discovered and recovered on the streets below so not really sure what that objection is all about either.
Steel is harder than aluminum? Sure, so what? That's about 1/100th of the information you need to figure out 9/11. It's about energy not materials. And besides, LIGHT could easily penetrate the Twin Towers http://i.imgur.com/hJdqzcp.jpg so 115 tons travelling at 466 mph is a dawdle.
Here's a fun test of your "steel is stronger than aluminum" theory though.. Get yourself an aluminum baseball bat. Now start hitting your car as hard as you can. Hood, doors, trunk/tailgate.Go to town. Which comes off better, the steel car or the aluminum bat?

So how did those wing tips magically cut through the solid steel facade? Please explain that one for me.

@12weasel100 - It craves attention. Do not feed it. It is not serious. Even if it were, has absolutely nothing of value to contribute (and at some level knows it).

@M Fitz Wow, you just happen to be the first to reply. Operation earnest voice hard at work here.

The wing "tips" did not "cut" through solid a solid steel facade, by magic or any other means. Therefore nothing needs explaining. The facade of the Twin Towers was obviously anything but solid steel. There were in fact 36" wide gaps between each 14" wide hollow steel box column made of just 1/4" A36 plate. Light could pass through the Twin Towers; http://i.imgur.com/hJdqzcp.jpg


No steel was "cut" by the wing tips or any other part of the plane. Study the imagery of the actual event. The wing tips destroyed the outer aluminum cladding and bent and twisted some of the perimeter columns, but did not "cut" any. Closer towards center of mass damage to the building becomes much greater, engines, fuselage and the robust inner wings bashing (not cutting) their way through the perimeter columns with little effort just as one one expect of a 115 ton object travelling at 466 mph. While a lot of the perimeter columns in this area are bent and twisted, none are cut. Complete column failures are mostly bolt shearing failures at the column ends where sections are bolted together. Nothing magic about it.


I hope this helped.

What a joke. I just watched a video of # 7 ,Police, and Fire fighters telling camera men to move back we'r about to blow that building up So for all you imbecilic retards go take a look, if I can find it so can you. Or get yourself another plate of ''Official'' dog shit..yes there's in depth interviews with them also...
