Hi JFK,

I'm not sure where the original footage is from, but it was created by a poster called femr2 over at the911forum.

He as an awesome 3d model of the WTC in which he can plug all kinds of numbers in to try and simulate the collapses.

It was not a controlled demolition and there was no thermite either.

Just lots of pretty sparks! :blink:
I notice the debunkers have been silent regarding your post, Stundie. Could it be the fact that jet fuel can't melt steel or aluminum into a liquid state?

If any debunker thinks jet fuel (kerosene) can melt steel or aluminum into a liquid state, take a gas can to your local gas station and fill it up with kerosene. Then go to your local hardware store and get some aluminum, preferably around .125" thick. Take them to your back yard, poor the kerosene on the aluminum and let it burn for an hour. Let us know how it turns out.

Well bonez, I am not a debunker however there is a fault with your statement.

If you feed a properly proportioned oxidizer into your jet fuel fire it can indeed melt aluminum.

Yes I know that there was no source for this properly proportioned oxidizer... Just trying to be accurate.

( I have seen many diesel engine pistons [ Aluminum alloy ] melted from being run too lean... When fuel/air ratios were set by manually by inexperienced mechanics )

here is good ol' Sami Kilic...Posted Image
weird...his middle name is "And" :blink:


......................."and" here is some of his special work..click me

from abstract
 
This paper describes the work of a team of researchers in computer graphics, geometric computing, and civil engineering to produce a visualization of the September 2001 attack on the Pentagon. The immediate motivation for the project was to understand the behavior of the building under the impact. The longer term motivation was to establish a path for producing high-quality visualizations of large scale simulations. The first challenge was managing the enormous complexity of the scene to fit within the limits of state-of-the art simulation software systems and supercomputing resources. The second challenge was to integrate the simulation results into a high-quality visualization. To meet this challenge, we implemented a custom importer that simplifies and loads the massive simulation data in a commercial animation system. The surrounding scene is modeled using image-based techniques and is also imported in the animation system where the visualization is produced. A specific issue for us was to federate the simulation and the animation systems, both commercial systems not under our control and following internally different conceptualizations of geometry and animation. This had to be done such that scalability was achieved. The reusable link created between the two systems allows communicating the results to non-specialists and the public at large, as well as facilitating communication in teams with members having diverse technical backgrounds.

I'm sure this has been covered but I'm VERY interested in how FIRE turned OVER 70 FLOORS of CONCRETE into PYROCLASTIC DUST. I'm sure the OP knows that pyroclastic dust only occurs in two scenarios. Volcano eruptions and building demolitions.
If a building collapses, you don't expect to see dust and debris?
Unfortunately no other buildings have "collapsed" from a "fire" so this one was a bit odd.

At what temperature does concrete turn to dust?

It is a straight conversion from the .flv download of the Google video ( using Orbit downloader ) to .jpg frames ( using Free Video to JPG Converter 1.4.3.50 ) which were then imported to JASC Animation workshop version 3.11 ( since bought by Corel ). The only edit is the circles highlighting the explosions which were done in JASC Animation workshop.

The other two are too large to host here at 10 and 12 MB. :-/

Great work with the gif and stills, JFK. This is some pretty startling evidence. I can't believe it went under the radar for so long. There certainly is some energy pushing that molten material out. Where did this energy come from, considering it happened so far down the building? More importantly where did the molten material itself come from?

Is this more evidence of the energetic nano-composite thermite recently confirmed in the dust from the towers?

I have my doubts of nanothermate being the cause of that as it is less than 1/3rd of a second on duration... and very high velocity.

There is also another starting about five floors above, but the clip ends too soon to get decent pics.

The timing of those two events is not unlike a controlled demolition.

Yeah I see what you mean. Super (or nano) thermite can however produce a fair amount of explosive pressure.

Quote:
 
"A graph in an article on nanostructured energetic materials [21] shows that the energy/volume yield for Al/Fe2O3 composite material exceeds that of TNT, HMX and TATB explosives commonly used in demolitions .... We suggest that the organic material in evidence in the red/gray chips is also highly energetic, most likely producing gas to provide explosive pressure. Again, conventional thermite is regarded as an incendiary whereas super-thermite, which may include organic ingredients for rapid gas generation, is considered a pyrotechnic or explosive."

This was one of the clips that long ago got me to start questioning what happened precisely, very strange. It sort of reminds me now of a Steven Jones demonstration I saw somewhere, testing out one of those linear thermite cutting charges. http://www.youtube.com/watch?v=Wn-MCCZ3O1M

It is also strange how this molten metal shows up just prior to collapse instead of the initial burning of Jet Fuel where the temps would be hottest. I found this while searching for Plane Aluminum possibilities: http://www.takeourworldback.com/smokinggun.htm

Quote:
 
Nist Question 11: Why do some photographs show a yellow stream of molten metal pouring down the side of WTC2 that NIST claims was aluminum from the crashed plane although aluminum burns with a white glow?

NIST reported (NCSTAR 1-5A) that just before 9:52 a.m., a bright spot appeared at the top of a window on the 80th floor of WTC 2, four windows removed from the east edge on the north face, followed by the flow of a glowing liquid. This flow lasted approximately four seconds before subsiding. Many such liquid flows were observed from near this location in the seven minutes leading up to the collapse of this tower. There is no evidence of similar molten liquid pouring out from another location in WTC 2 or from anywhere within WTC 1.

Photographs, and NIST simulations of the aircraft impact, show large piles of debris in the 80th and 81st floors of WTC 2 near the site where the glowing liquid eventually appeared. Much of this debris came from the aircraft itself and from the office furnishings that the aircraft pushed forward as it tunneled to this far end of the building. Large fires developed on these piles shortly after the aircraft impact and continued to burn in the area until the tower collapsed.

NIST concluded that the source of the molten material was aluminum alloys from the aircraft, since these are known to melt between 475 degrees Celsius and 640 degrees Celsius (depending on the particular alloy), well below the expected temperatures (about 1,000 degrees Celsius) in the vicinity of the fires. Aluminum is not expected to ignite at normal fire temperatures and there is no visual indication that the material flowing from the tower was burning.

Pure liquid aluminum would be expected to appear silvery. However, the molten metal was very likely mixed with large amounts of hot, partially burned, solid organic materials (e.g., furniture, carpets, partitions and computers) which can display an orange glow, much like logs burning in a fireplace. The apparent color also would have been affected by slag formation on the surface.


This is certainly an interesting phenomenon. At least NIST are honest and realistic enough to admit that the aluminum did not burn and thereby generate heat, since that would have required it to have been in the form of flakes or a fine powder.

Suppose we take an (on the high side) estimate of 1000 C for flame and hot gas upper layer temperatures in very close proximity to a plate of aluminum alloy just as it is supposed to have melted. If the aluminum was at the low end of the aircraft fuselage skin thickness range at some 0.03 inches or 0.000762 m and its area was 0.485 m^2, this would place the volume of the piece around 0.00037 m^3 and hence its mass would be 0.00037 * 2700 kg/m^3 ~ one kilogram. The heat required to melt this is given by the temperature increase of (660 - 25) which is 635 degrees K times the heat capacity of 900 J/kg.K (it's actually more than this over the range up to 660 C) which comes to 571,500 J, plus 397 kJ for the latent heat of fusion, to give a total requirement of 968.5 kJ. After allowing for elements such as zinc in the alloy, the melting point, specific heat and enthalpy of fusion would be slightly lower.

So we have this piece of aircraft debris which just happens to have settled such that its 0.485 m^2 area side is squarely facing the radiant heat from the flames of burning office stationery, carpets, workstations, etc, and in a vertical position against the wall at the top of a window. Suppose it has already reached 660 C (or slightly less for the alloy), after absorbing the initial 571.5 kJ. The rate of radiant heat transfer is related to the difference in the fourth powers of the absolute temperatures of emitter and absorber:

P = e * lowercasesigma * A * (Te^4 - Ta^4)

For the moment, we suppose emissivity e = 1. Taking the Stefan-Boltzmann constant (lowercasesigma) as 5.6703 * 10^-8 W/m^2.K^4, we have:

P = 5.6703 * 10^-8 * 0.485 * (1273^4 - 933^4) = 51.382 kW.

(If the emitter temperature is lowered from 1000 to 900 C, P drops to 31.225 kW.)

At 397 kJ required to melt the 1 kg after it has reached the melting point, the time required is 397 / 51.382 = 7.726 seconds, or slightly less for the alloy, or almost 12.7 seconds assuming 900 C for the emitter temperature.

A major problem with the "melting aluminum" theory is that aluminum is a poor absorber of radiant heat. Although it is not unreasonable to take 1 as the emissivity of flames, aluminum has an emissivity of only about 0.1. This is why it is used as a reflector in infrared heaters. Also, for a thin plate of aluminum, some radiation would be transmitted through it. Moreover, the location by the window would result in a further 40% or so reduction. At 1000 C (flame) and 660 C (aluminum) the potential aluminum absorption is proportional to 1273^4 - 933^4, i.e. 1.868*10^12, and it would be likely to transmit an amount to the exterior proportional to 933^4 - 298^4, i.e. 7.499*10^11. If in close contact with the wall, it would conduct heat to it.

Most of the radiant heat striking the aluminum would be reflected back, and would probably end up being vented out to drive the smoke plume.

A ten-fold adjustment raises the minimum time for melting of the 660 C aluminum from the above 7.726 seconds to 77.26 seconds. Yet there was enough melting liquid to be clearly visible, and to sustain a four-second flow before subsiding. Even if the whole 1 kg had somehow resisted melting for 77 seconds whilst receiving heat at 660 C, and then the entire piece suddenly melted within a mere 4 seconds, aluminum only expands by about 12% when molten to a density of 2400 kg/m^3. So the 1 kg would have a volume of 417 ml which is barely more than the contents of a can of Coke. The video evidence shows that the flow was much more than 100 ml per second, and at times more like a "waterfall". And...

Many such liquid flows were observed from near this location in the seven minutes leading up to the collapse of this tower.

...which would be many, many kilograms of aluminum, and would require a greater energy source than a few burning papers and carpets in an office compartment fire.

There was aluminum cladding on the exterior columns, but this was on the three exterior sides and on the wrong side of fire-resistant plaster. The flows of molten liquid support the theory that thermite or thermate played a part in weakening columns over the space of several minutes leading up to each collapse. It is hardly surprising that guards were immediately placed at the crime scene, Ground Zero, to prevent independent investigators from getting hold of samples of steel, and a couple of weeks later Mayor Giuliani even banned photography at the site.

Conclusion
We conclude that some WTC structural steel melted, and molten iron was formed, by a type of combustion such as a thermite reaction, as opposed to hydrocarbon fires of office combustibles ignited by jet fuel. WTC 1, 2 and 7 were subjected to controlled demolitions involving pre-installed accelerants.

So post a video, show me where I can find even fifty people who say they saw this series of detonations going off.

Can you please provide a link to that quote that you posted?? I would love to see where you got it from.

And, why is it that you seem to think that huge columns, or pieces of metal crashing into each other WOULDN'T creaate a loud bang?? Heck, hitting a hammer on a piece of steel is loud enough to be heard from 3 doors down my block.

Ok, I just watched the first 1:30, and they have already claimed that a helicopter caused the collapse of the S. Tower. Come one, this is your evidence?? Hopefully it gets better.

Will this work ?
