I've read the article you linked Min in closer detail. There's some things that aren't adding up to me:
The AE911Truth team stated that it was the American Society of Civil Engineers themselves that violated the usual procedure of investigating a collapsed building. If this is true, then it puts the post-research they did into question.
It might be possible that the jet fuel left the structure weakened to the point of collapse, but it doesn't explain molten iron/steel found beneath the rubble, as both building materials require temperatures closer to 3 000F to melt: http://www.engineeringtoolbox.com/meltin...d_860.html
Well.. the hr long video *is* the entirety of the evidence found for a demolition, of which the official report didn't find because they stated (paraphrasing) "we didn't search for evidence of explosives".
On the other hand, I've found a good website stating the opposite to what some of the video said: http://911research.wtc7.net/reviews/Nati...-4067.html
*sigh* why do I even bother opening this new can of worms... religion keeps me busy enough.
Quote:The collapse was caused by fire initially fed by the jet fuel from the planes.
Science: 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.

Quote: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.

Quote: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.
