National Geographic TV Debunks 9/11 Conspiracy Theories Monday

UPDATE: More promo videos at end of post.

Calling all 9/11 Truthers: the National Geographic Channel will be airing a program on Monday evening that will debunk many of your conspiracy theories.

Aptly named "9/11: Science and Conspiracy," the special aims to address some of the most common connivances espoused by wackos like Rosie O'Donnell.

Such theories include (video preview embedded below the fold, h/t Craig Moncho):

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 checmical 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.

This should be required viewing for all Truthers.
