Don't forget about the fire in 1975 that burned for over 3 hours and casued no damage to steel beams.
Yet we are to believe that isolated fires burning for less then an hour weakened several steel beams.

And of course those were just fires with no structural damage, and the fire protection systems were not destroyed as well. But then the whole argument depends on separating all the evidence and analyzing it all as separate pieces rather than using it all together. Because to do so would not make for good sensationalism.

If "all the evidence one should need to see" consists of the collapse "looking like" something, and common sense, then your standard of evidence has to be very low.
2. Why did NIST not consider a “controlled demolition” hypothesis with matching computer modeling and explanation as it did for the “pancake theory” hypothesis? A key critique of NIST’s work lies in the complete lack of analysis supporting a “progressive collapse” after the point of collapse initiation and the lack of consideration given to a controlled demolition hypothesis.
-------------------------------------------------------------------------------------
NIST’s findings also do not support the “controlled demolition” theory since there is conclusive evidence that:
the collapse was initiated in the impact and fire floors of the WTC towers and nowhere else, and;
the time it took for the collapse to initiate (56 minutes for WTC 2 and 102 minutes for WTC 1) was dictated by (1) the extent of damage caused by the aircraft impact, and (2) the time it took for the fires to reach critical locations and weaken the structure to the point that the towers could not resist the tremendous energy released by the downward movement of the massive top section of the building at and above the fire and impact floors.
Video evidence also showed unambiguously that the collapse progressed from the top to the bottom, and there was no evidence (collected by NIST, or by the New York Police Department, the Port Authority Police Department or the Fire Department of New York) of any blast or explosions in the region below the impact and fire floors as the top building sections (including and above the 98th floor in WTC 1 and the 82nd floor in WTC 2) began their downward movement upon collapse initiation.
In summary, NIST found no corroborating evidence for alternative hypotheses suggesting that the WTC towers were brought down by controlled demolition using explosives planted prior to Sept. 11, 2001. NIST also did not find any evidence that missiles were fired at or hit the towers. Instead, photographs and videos from several angles clearly show that the collapse initiated at the fire and impact floors and that the collapse progressed from the initiating floors downward until the dust clouds obscured the view.

I haven't read through this redundant thread all the way but is it safe to guess that someone already tried to use the hotel in Madrid as well? Have we covered all the cliche arguments?
I suppose if the same argument is rehashed over and over enough times we can convince ourselves that what we want to believe is really true.
Fires Have Never Caused Skyscrapers to Collapse
Excepting the three 9-11 collapses, no fire, however severe, has ever caused a steel framed high-rise building to collapse. Following are examples of high-rise fires that were far more severe than those in WTC 1 and 2, and Building 7. In these precedents, the fires consumed multiple floors, produced extensive window breakage, exhibited large areas of emergent flames, and went on for several hours. The fires in the WTC towers did none of these things.
1. The One Meridian Plaza Fire
One Meridian Plaza is a 38-floor skyscraper in Philadelphia that suffered a severe fire on February 23, 1991. The fire starting on the 22nd floor, and raged for 18 hours, gutting eight floors and causing an estimated $100 million in direct property loss It was later described by Philadelphia officials as "the most significant fire in this century".
The fire caused window breakage, cracking of granite, and failures of spandrel panel connections. Despite the severity and duration of the fire, as evidenced by the damage the building sustained, no part of the building collapsed.
2. The First Interstate Bank Fire
The First Interstate Bank Building is a 62-story skyscraper in Los Angeles that suffered the worst high-rise fire in the city's history. From the late evening of May 4, 1988 through the early morning of the next day, 64 fire companies battled the blaze, which lasted for 3 1/2 hours. The fire caused extensive window breakage, which complicated firefighting efforts. Large flames jutted out of the building during the blaze. Firefighting efforts resulted in massive water damage to floors below the fire, and the fire gutted offices from the 12th to the 16th floor, and caused extensive smoke damage to floors above. The fire caused an estimated $200 million in direct property loss.
A report by Iklim Ltd. describes the structural damage from the fire:
In spite of a total burnout of four and a half floors, there was no damage to the main structural members and only minor damage to one secondary beam and a small number of floor pans.
3. The 1 New York Plaza Fire
1 New York Plaza is a 50-story office tower less than a mile from the World Trade Center site. It suffered a severe fire and explosion on August 5, 1970. The fire started around 6 PM, and burned for more than 6 hours
4. Caracas Tower Fire
The tallest skyscraper in Caracas, Venezuela experienced a severe fire on October 17, 2004. The blaze began on the 34th floor and spread to over 26 floors, and burned for more than 17 hours. Heat from the fires prevented firefighters from reaching the upper floors, and smoke injured 40 firefighters.

So, we can't compare the towers or 7 with other buildings. Now, we can't even compare the towers to themselves? How telling.

Gee you should really look at more steel buildings then just Madrid hotel. Thier are at least 4-6 different steel buildings that i can bring up that burned several hours some for over a day and had structural damage due to the fires and did not collapse like the towers or building 7.

NOVA: A common misconception is that you blow buildings up. That's not really the case, is it?
Stacy Loizeaux: No. The term "implosion" was coined by my grandmother back in, I guess, the '60s. It's a more descriptive way to explain what we do than "explosion." There are a series of small explosions, but the building itself isn't erupting outward. It's actually being pulled in on top of itself. What we're really doing is removing specific support columns within the structure and then cajoling the building in one direction or another, or straight down
"The roof did its job, the gravity engine worked. It provided the energy we needed to pull the columns inward," said Mark Loizeaux, president of Controlled Demolition Inc., the Maryland-based company whose handiwork brought down the Dome.
One of the more amusing mythologies of the 9/11 denial movement is the claim that the phrase "pull it" is an industry term for demolishing a building with explosives.
We have never once heard the term "pull it" being used to refer to the explosive demolition of a building, and neither has any blast team we've spoken with
(2) The Fire Department may pull down or demolish any building or structure
when considered necessary to prevent the spread of fire.

How can people say this????
I do beileve they [The American Government] turned a blind eye to the threat and then took advantage of the situation, but to say 9/11 was an inside job is BS.

I so hope you are kidding. Your article includes the madrid building. But you forget to mention that it was mostly concrete and that the steel part of the building DID collapse from the fire.

Actually, the burden of proof is on whoever is trying to prove something.
As far as the CD theorists go, the burden is on them to prove their theory as well.
If you want people to believe your theory, then present some solid positive evidence in favor of the theory.
There is no evidence that bombs were even in Building 7, just as there is no evidence that elephants were in the building.
So, enough dodging, does anyone have positive evidence for the existence or use of explosive devices at Building 7 that day?
Or is it as I said, that there is no positive evidence for bombs?

And you consider broken windows to be structural damage?
Who are you guys trying to kid here????
