9/11 Science and Conspiracy

Speedy 2012/06/22 03:39:03
Here is National Geographic 9-11 Science and Conspiracy video. The documentary of the September 11, 2001 terrorist attacks proves the conspiracy theories to be false.

With the use of high-tech forensic experiments, eyewitness footage, CGI re-creations, and an in-depth analysis by experts and theorists on all sides of the story, the documentary attempts to examine both alleged conspiracies and available evidence.

The documentary, National Geographic 9-11 Science and Conspiracy sets out to conduct a forensic investigation designed to test various tenets of some common 9-11 conspiracy theories. What caused the collapse of the Twin Towers? Was it from the fires, or were explosives placed inside the buildings, causing them to implode? Did a missile, rather than a commercial airline jet strike the Pentagon?

CONSPIRACY VS. SCIENCE

Conspiracy theories are put to the test. How well do they stand up against the visual simulations of professional engineers? See how science supports official stories and debunks the conspiracies below.

THE COLLAPSE OF THE BUILDINGS

Official Story: The collapse was caused by fire initially fed by the jet fuel from the planes.
Testing the Official Story: Using original construction blueprints, photographs, and construction data, Purdue University, along with the American Society of Civil Engineers, created a model structure of the north World Trade Center tower and a scaled 767 jetliner. To model the fuel load, Purdue launched aluminum cans filled with liquid to represent an airline wing colliding with a steel column. The final simulation showed the internal destruction of supporting columns, the disintegration of the jetliner, the atomizing of the fuel, and the resulting fires that softened the steel framework of the building and brought it down.

Conspiracy: The fire could not have gotten hot enough to melt the steel.
Science: The Energetic Materials Research and Testing Center (EMRTC) designed explosives to test the effects of burning jet fuel on steel. EMRTC used a bare steel beam because the National Institute of Standards and Technology reports that much of the any fireproofing material would have been knocked off at the moment of impact. Within two minutes of igniting the fuel, the temperature peaked just above 2,000 Fahrenheit and complete structural failure occurred in less than four minutes.

Conspiracy: The collapse was caused by controlled demolition.
Science: The film crew recorded the demolition of a college dormitory building to learn all that is involved in the process of prepping and loading. The first step was to expose the columns in order to attach explosives to them. The World Trade Center had 47 inner core columns that would have needed to be prepared. To cut the steel beams the demolition team used a shape charge, which is piece of copper apportioned to a shape-charged weapon. When an explosive is attached and ignited, the device implodes and forms a stream of liquid copper that cuts through the steel. A demolition of this scale would leave clear evidence behind, but no such traces were found at Ground Zero.

Conspiracy: Thermite, which is less traceable, was used in the controlled demolition that brought down the towers.
Science: Some Truthers claim that pulverized dust found by some New Yorkers after the attack contained the chemical signature of thermite. Scientists assert that even if this dust did contain thermite, it would be impossible to determine whether the thermite came from a controlled demolition or simply from the melting of the airplanes. EMRTC designed an experiment to see if thermite was a plausible option in the collapse of the towers. The thermite in the test was not even able to melt a column much smaller than those in the World Trade Center.

THE ATTACK ON THE PENTAGON

Official Story: Hijackers caused a commercial airplane to crash into the building.
Testing the Official Story: Purdue University created a visual simulation of the crash, which indicated the victims’ bodies would have been pushed forward in relation to one another, just as they were in the actual attack. To further investigate, EMRTC launched a projectile into a simulated structure. They did not include wings in the projectile model because Purdue asserted they were of little consequence as the Pentagon was so heavily reinforced. The experiment created a hole in the structure the approximate size of the projectile - similar to photo evidence from the actual attack.

Conspiracy: The Pentagon was either bombed or hit by a missile.
Science: EMRTC also planted an explosive in the same model structure and compared the results to photos of the Pentagon after the crash. The explosive test demonstrated a different sort of damage. The structure blew out from the point of the explosion, causing complete destruction of floors and walls. This dispersed debris did not match the photo evidence.

    Big Bag of BS! You people are so gullible. They have come up with thousands of bogus scientific experiments to debunk what most will tell you was an inside job. There are over 3,000 qualified Scientists and Engineers around the globe that will heartily disagree with this video and all that say that two 100 story buildings fell in almost twin falls in their own footprints. The odds of this ever happening are astronomical by any stretch of the imagination. The US govt assisted in the take down of these buildings to complete a needed scenario for the removal of civil liberties in this nation. They succeeded, and idiots are still letting them get away with it. Congratulations, you people have won the morons of the century award.

    My friend, the biggest crime done to the American people NEEDS better attention. Why would you want to divert attention?

    Well first of all, I don't have human trash people like yourself as friends. Secondly, why don't you drink some cold water and slow down your stupidity? I see the racism is the part that running your motor, eh? Are you talking about attention? Hahaha, no brain - no worries! To remind you, you comes to post your racism on my posts, you such an attention whore. ~Oops~

    Is it, so why don't you prove that? Inside job is the BS, and you conspiracy pricks are denying scientific facts while you brought your agenda instead facts to the table. America killed its own people, you guys are nutjobs!

    The problem is, you don't really want to know the truth. It would destroy your delusional picture of this nation. The Govt is not your friend, the Elite don't give a crap about you. Big bankers have their own agenda, you are simply a pawn and chattel in their game. Stop being a comatose puppet. Now watch this video, and open your mind, before the denseness takes over completely.

    9/11 conspiracy nuts just don't have the educational or common sense reasoning skills to understand their partisan 'theory'.

    Despite being my college education (architecture and metallurgy), I have years of hands on experience working with steel structures.

    The last thing I want to hear is someone bumbling conspiracy idiot telling me about what steel does or does not do.

    Here are the facts:

    Carbon steel MELTS around 2600 to 2800 degrees. IT DOES NOT NEED TO MELT TO EXCEED IT'S YIELD STRENGTH!!!!!!

    The lower transformation phase (change of the structure of the steel) of carbon steel is 1333 degrees. The steel only has to be WEAKENED by heat to lose it's ability to sustain an applied load. The applied load would be the weight of the building above the point of heating. The more weight, the shorter amount of time it takes to exceed it's load carrying capacity.

    Another similarly constructed steel building collapse from fire:

    Don't even try. The conspiracy nuts are never going to accept facts as truth. They have already invest too much into their hair-brained scheme.

    Not buying into this..."They did not include wings in the projectile model because Purdue asserted they were of little consequence" really! a scientific study? pfft wings would have left marks period. Ever see the hole before the wall collapsed? No way would that plain fit. the engines and landing gear vaporized? impossible. most people assume jet fuel is this super high octane stuff.....google it, lol!

    "Not buying into this"... yes, you are cheap person. lol
    There are so many investigation about 9/11 which you conspiracy nuts "don't buy into any of them", also if you got NO proof of these none sense claims of these conspiracy nutjobs, you rather hide your head in the sand instead seeing the facts.
    nuts buy proof claims conspiracy nutjobs hide head sand facts

    The evidences are all over the net, you may search the truth. You may start with this video... Good luck! And btw: I see you have sense of humor failure if you didn't understand my sarcasm about the "cheap person". lol
