616447 2007-12-04 08:31:00 So what caused WTC7 to collapse?I reckon if 220 stories of buildings collapsed it'd be similar to a significant earthquake. So not only the shockwaves but also the enormous amount of debris flung around would've been sufficient to cause it's collapse. Greg (193)

Meh. No way. And again, straight down? Wouldn't one side of it have sustained most of the damage, if any? Buildings don't fall down like that.... 		wratterus (105)

Thats about the most ridiculous thing i've ever heard !

If you werent joking there Greg i suggest you book your flight to Mars yourself:thumbs:

Nobody has an answer as to why WTC7 collapsed.

Next we'll be told it didnt collapse at all;) 		russell108 (7499)
616450 2007-12-04 08:53:00 So what caused WTC7 to collapse?

From Popular Mechanics website. (www.popularmechanics.com)

"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.

Second, a fifth-floor fire burned for up to 7 hours. "There was no firefighting in WTC 7," Sunder says. Investigators believe the fire was fed by tanks of diesel fuel that many tenants used to run emergency generators. Most tanks throughout the building were fairly small, but a generator on the fifth floor was connected to a large tank in the basement via a pressurized line. Says Sunder: "Our current working hypothesis is that this pressurized line was supplying fuel [to the fire] for a long period of time."

WTC 7 might have withstood the physical damage it received, or the fire that burned for hours, but those combined factors — along with the building's unusual construction — were enough to set off the chain-reaction collapse." 		Deane F (8204)

And you beileve all that do you :lol:

[i]"NIST investigators believe a combination of intense fire and severe structural damage contributed to the collapse, though assigning the exact proportion requires more research .

one of the many criticisms of the official govt . story is that unlike any other building fire/collapse, the scene was immediately removed and the wreckage/debris never examined where they had fallen - which is a breach of very common laws designed to help find the cause and mode of failure

really the only thing going for the official story is the sheer scale of this conspiracy, and the lack of solid evidence for either side


though i did read an interesting one about how the jews, which run the world's governments and media, not only orchestrated 9/11 but nearly all the major attacks/disasters in modern history . . . even had some "facts" about how some numbers in the virginia tech massacre (jews did that too) were associated to the star of david through several degrees of manipulation so it must be true:lol: 		motorbyclist (188)
616454 2007-12-04 17:54:00 Cannot see the jews running Helen government!, but then we are not much of a country anyway.

September 6 2007, jew airstrike on Dayr az Zawr, saved us again from potential WW111, averted once again according to Spectator article.

Actually, I don't care one way or the other .

Quite . But there is a lot of information out there for the interested and that was the point of the link and the quoted text .

Some people form their opinions - and some people inform their opinions before they form their opinions . It seems to me that the conspiracy theorists I have come across are of the former bunch rather than the latter . :2cents: 		Deane F (8204)
