Re Deleted 911 Thread

Claim Three:
“Tower 7, which wasn’t hit by a plane, collapsed neatly into its own footprint.”

The enigma of WTC 7 is becoming increasingly popular in Truther circles. We’re told that it wasn’t hit by a plane and was subjected to just a few “small office fires.” Yet it collapsed anyway, late in the afternoon of September 11, “falling neatly into its own footprint at freefall acceleration, just like a normal controlled demolition.” In particular, Truthers point to a brief period of freefall (2.25 seconds) that was confirmed by NIST in its WTC 7 final report (Sunder 2008; NIST 2010) as proving that the building was purposely imploded. However, WTC 7, too, fails to prove 9/11 was an “inside job”:

What is often conveniently left out of the story are actual reports from NYFD firefighters at the scene, which describe huge, raging, unfought fires on many floors at once and visible deformations and creaking of the building prior to its collapse (Roberts 2008). Tower 7 was not hit by an airplane; however, it was struck by a 110-story flaming skyscraper, the North Tower. The fires raged for hours, and they eventually caused a critical column (#79) to fail because of thermal expansion; NIST determined that this column was crucial to the building and could even be considered a design flaw. Its failure would have collapsed the building even without the other structural damage from WTC 1’s collapse and the fires.

WTC 7’s brief 2.25 seconds of free fall is now the Truthers’ best “smoking gun.” The claim usually goes like this: “The fifty-eight perimeter columns would have resisted and slowed the collapse to much less than freefall. The ‘freefall’ of WTC 7, admitted to by NIST, proves it was controlled demolition.” The problem is that this is a straw man argument. NIST found the collapse occurred in three stages. The first stage, which lasted 1.75 seconds, is when the fifty-eight perimeter columns were buckled; during this interval, the rooftop actually fell only about seven feet. This is because the breaking of columns saps speed, indeed making the collapse slower than free fall. In the second stage, which lasted 2.25 seconds, the already-buckled columns provided negligible support, and the north face of the structure free-fell about eight stories. (Try taking a plastic drinking straw and buckling it by folding it over and then pushing down on the bent straw with your hand. The crimped straw provides almost no resistance to vertical forces, and neither did the buckled columns of WTC 7.) The third stage described by NIST, which lasted 1.4 seconds, was again less-than-free fall, as the structure fell another 130 feet as it impacted more non-buckled structures toward the bottom of the building (NIST 2010).

The other half of the equation is that WTC 7 resembles a “classic controlled demolition” because it supposedly “imploded, collapsing completely, and landed in its own footprint” (Gage 2011). In actuality, it twisted and tilted over to one side as it fell, and parts of the building severely damaged two neighboring buildings (the Verizon and Fiterman Hall structures). When challenged with the obvious fact that Tower 7 spilled far outside its footprint, however, Truthers will often change their tune and start saying that any resemblance to a natural collapse is part of the cover-up.

How does a fire burn underground like that without an oxygen source?

Some unbelievable crack flying went into hitting the Pentagon

Picking and choosing what you want to believe is not what truth is about.

[T]here are known knowns; there are things we know that we know.
There are known unknowns; that is to say there are things that, we now know we don't know.
But there are also unknown unknowns – there are things we do not know we don't know.


—United States Secretary of Defense, Donald Rumsfeld

Certainty isn't truth. But what is likely true for anyone on either side of this, is that what today is for you a known known is actually an unknown unknown, and if you're lucky someday you'll recognize it as a known unknown.

Truthers don't believe all conspiracy theories; some must look at people espousing the belief that aliens left a massive ark on the moon as being real whack-jobs--and it must be irksome to have others treat you like that guy when you are so certain of what you "know".

And what irks me about most truthers is the tone, and often outright statements which say, "if you don't agree then you are blind, a sheeple, an idiot, a moron, in on the conspiracy, a dupe, a fool, naive, etc.," just because I can tolerate having a few more known unknowns than them.

Are you into counter-intelligence? You just twisted the most bizarre pretzel I've seen since...WTF is your f*#king point?

You can not lay down your point in a more coherent fashion? You must be psy-ops or counter-intel. WTF? Or just f*#king crazy.....
