NIST investigators believe a combination of intense fire and severe structural damage contributed to the collapse, though assigning the exact proportion requires more research. But NIST's analysis suggests the fall of WTC 7 was an example of "progressive collapse," a process in which the failure of parts of a structure ultimately creates strains that cause the entire building to come down. Videos of the fall of WTC 7 show cracks, or "kinks," in the building's facade just before the two penthouses disappeared into the structure, one after the other. The entire building fell in on itself, with the slumping east side of the structure pulling down the west side in a diagonal collapse.
According to NIST, there was one primary reason for the building's failure: In an unusual design, the columns near the visible kinks were carrying exceptionally large loads, roughly 2000 sq. ft. of floor area for each floor. "What our preliminary analysis has shown is that if you take out just one column on one of the lower floors," Sunder notes, "it could cause a vertical progression of collapse so that the entire section comes down."
There are two other possible contributing factors still under investigation: First, trusses on the fifth and seventh floors were designed to transfer loads from one set of columns to another. With columns on the south face apparently damaged, high stresses would likely have been communicated to columns on the building's other faces, thereby exceeding their load-bearing capacities.
fascinating to note that many who believe these 9-11 conspiracies are the same ones who wonder if the Holocaust really occurred.
Wouldn't that be true because its a matter of perspective? Some people do believe the government of the United States are doing things that some would label conspiracies, because of entities like the FBI,CIA, and others. Of course to be objective if those 1st two mention can't/won't even share data when it even involves the security of a nation its probably doubtful that high maintenance conspiracies could be operated. I think it just boils down to some people trust, some don't.Yeah . . . There aren't too many people who only believe in one conspiracy theory. Typically the same people who think there was something fishy about 9/11 also lay in bed at night wondering about the Holocaust and why we made a "lunar" landing at Area 51.
You threaten a couple of people and tell everybody there's a bomb on board.how the hell do you highjack a plane with box cutters!? (It's the reason that even nail clippers became forbidden on flights.)
Not sure I understand what you are saying. Who are you calling "highest tier staff of the WTC"?In no way am I saying this was an act by the governemnt, hell, if anything I'd say that the highest tier staff of WTC would be the main ones to blame if these were to be put to the main media (CBS, NBC etc).
3,000 people dying on a September morning not grim enough for you?my teachers love controversial subjects that aren't too grim. :idea:
