Scientists simulate jet colliding with World Trade Center

Purdue University has provided a computer simulation showing on how a plane could take down the Trade Towers. This was funded by the National Science Foundation to determine better ways to protect buildings if this event were to occur again.

Purdue University Simulation

There may be a deafening silence to follow...

Thanks for adding that one. I cannot access YouTube very easily from my work.

There is a deathly silence because that doesnt show anything new or anything that anyone didnt already know!

It doesnt show how a plane could take down the towers it just shows a simulation of a plane crashing into the towers!

A simulation bieng guess work based on events of the day!

This is great!

Maybe these finding can sway my stance on the issue. I can't wait to see the results from the fire that contributed to the collapse. I wonder how long they will allow the fire to burn in the simulation to allow the collapse of the building. If it's within a couple hours of the actual time it took, this may well change my mind.

But, next they need to make the WTC7 collapse from debris damage and fire. And then simulate how the buildings in fron of WTC7 didn't collapse.

the video has its own thread here...

it covers 3/4 of a second and shows an excellent simulation. it does not show in any way shape or form how the jetliner brought down the towers. it shows what a colision would look like for 3/4 of a second.

but it will - supposedly. well, what I mean to say is that they are going to try to make it simulate the collapse. honestly, I don't see how students at a university could prove any more than the official review could (if you remember they had trouble making it collapse). in the article it states that this is the first leg of the simulation. next is to cause the fires. I guess they're going to add a tolerance to each steel beam in the building and simulate the heat that occurs from jet fuel and see if they can't get a pancake collapse. i find this study very interesting being that I am a doubter of the official story.

If that's what they are doing, they are only showing a computer animation of it. Not a real computer simulation of the finite element analysis. If so, they wouldn't need to because NIST already has theirs. Too bad they couldn't get the towers to collapse without tweeking the variables to outrageous numbers.

That's interesting. But, since they don't have structural drawings, they are wasting their time and only comming up with a computer animation , that's all.

NIST has the drawings but didn't get them to collapse. How do Purdue students think they would know more?

I guess that the NIST and FEMA reports are wrong when they stated the builidngs withstood the planes impacts ?

I also like how this animation shows the aluminum plane being shreded by the steel beams but in the Pentagon animated drawing they did the plane stays pretty well intact as it goes through the reinforced concrete wall and the inside collums and walls.

yep, the animation should not be construed as a forensic analysis
of videos that captured the events/evidence of that day.

if they really wanted to do something worthwhile
Purdue should have compiled the actual video evidence in a real time fashion.
so that a real analysis could be made of what appears in the video footage
and we all could debate things like,
the floor truss support anchors suddenly breaking free of the perimeter columns (outside walls)
was the cause for the sudden collapse of the top 10 stories identified as the tower section...

i think the Purdue team is/was just practicing for future work

Bush almost got his money's worth...

INDIANAPOLIS — A computer simulation of the 2001 World Trade Center attacks supports a federal agency's findings that the initial impact from the hijacked airplanes stripped away crucial fireproofing material and that the weakened towers collapsed under their own weight.

Folks, this is a computer ANIMATION, not a computer ANALYSIS! A computer analysis would require Finite Element Analysis - linear and non-linear (FEA), Computation Fluid Dynamic Analysis (CFD), Thermal Analysis, and structural Dynamic Analysis on a nodal level. This would require computing power far beyond anything available at the University level. Each and every material from the plane to the building itself would have to be replicated; density, tensile strength etc... The building would need to be replicated down to every nut, bolt and washer and the plane to every rivet and screw. Environmental conditions would also have to be replicated.

To date I am not aware of a single accurate and detailed computational analysis of the events of 9-11. I've sold Enginerring Software for almost 20 years and I know this stuff, intimately. This is a cute animation but nothing more - kinda like Shrek! Don't put any stock in this.

I would think this is governmental supportet: Disinfo.

Hey I'm with ya on this. Hope people aren't getting the wrong idea here since I'm looking forward to the findings. I'm actually hoping this disproves the official story.

Maybe I didn't understand the article correctly.

"This required a tremendous amount of detailed work," Hoffmann said. "We have finished the first part of the simulation showing what happened to the structure during the initial impact. In the coming months, we will explore how the structure reacted to the extreme heat from the blaze that led to the building's collapse, and we will refine the visual presentations of the simulation."

I took this to mean that they were conducting a scientific study using the actual physical dynamics of the structure/impact/heat/etc. and not just producing an animation of the basic collapse.

If it's just an animation of the collapse why not just call up Peter Jackson because it's all just BS that's been done. Maybe PJ could add some decent symphonics and actors, as well.

Please remember that the purpose of the study was to determine a way to prevent this type of collapse from happening in the future. So they may be going about the analysis in a different way than you expect.

Just a thought, I do not know much about the scientific research methods used in studies like this.

please note that a computer generated cartoon is still a cartoon (anime?) and therefore carries no weight in an investigation, does it?

it's been said before, i know, sometimes the blunt approach works best.

According to this "simulation", the central steel columns were made of paper, not steel.

How about an animation showing how squibs can shoot out of the tower, dozens of floors below the pancake area, during a "collapse". Or how about a simulation showing how a collapsa can generate enough horizontal force to shoot steel beams like bullets into neighbouring buildings.

What I'd really like to see is an animation showing how it really happened

These are the students and school that I admire.

This shows absolutely nothing. it's just a simulation, it doesn't even show why the towers collapsed. it's all theory and a waste of time.

Yet again, a study done which fits a predetermined hypothesis..

Fireproofing or not, it makes absolutely no difference. It is simple physics that jet fuel can not burn hot enough to melt or weaken steel. Combine that with the sheer size of the core columns, and the number of them, aswell as the conduction of heat away from zone of heating.. and you have yourself a bogus simulation.

That is all irrelevant anyway once you come to realise the simple truth that no planes hit the towers..

Aluminium planes can slice through steel box columns like butter.. Jet fuel fires can weaken high grade steel.. A pancake collapse can pulverize 99% of the building into micron fine powder.. And still have enough energy left over to keep steel molten in the basement of the WTC for 100 days..

Hurray for cartoon physics!!
