(AP)  Federal investigators said Thursday they have solved a mystery of the Sept. 11, 2001 attacks: the collapse of World Trade Center building 7, a source of long-running conspiracy theories.

The 47-story trapezoid-shaped building sat north of the World Trade Center towers, across Vesey Street in lower Manhattan. On Sept. 11, it was set on fire by falling debris from the burning towers, but skeptics have long argued that fire and debris alone should not have brought down such a big steel-and-concrete structure.

Scientists with the National Institute of Standards and Technology say their three-year investigation of the collapse determined the demise of WTC 7 was actually the first time in the world a fire caused the total failure of a skyscraper.

"The reason for the collapse of World Trade Center 7 is no longer a mystery," said Dr. Shyam Sunder, the lead investigator on the NIST team.

Investigators also concluded that the collapse of the nearby towers broke the city water main, leaving the sprinkler system in the bottom half of the building without water.

The building has been the subject of a wide range of conspiracy theories for the last seven years, partly because the collapse occurred about seven hours after the twin towers came down. That fueled suspicion that someone intentionally blew up the building in a controlled demolition.

Critics like Mike Berger of the group 9/11 Truth said he wasn't buying the government's explanation.

"Their explanation simply isn't sufficient. We're being lied to," he said, arguing that there is other evidence suggesting explosives were used on the building.

Sunder said his team investigated the possibility that an explosion inside the building brought it down, but found there was no large boom or other noise that would have occurred with such a detonation. Investigators also created a giant computer model of the collapse, based partly on news footage from CBS News, that they say shows internal column failure brought down the building.

Investigators also ruled out the possibility that the collapse was caused by fires from a substantial amount of diesel fuel that was stored in the building, most of it for generators for the city's emergency operations command center.

The 77-page report concluded that the fatal blow to the building came when the 13th floor collapsed, weakening a critical steel support column that led to catastrophic failure.

"When this critical column buckled due to lack of floor supports, it was the first domino in the chain," said Sunder.

The NIST investigators issued more than a dozen building recommendations as a result of their inquiry, most of which repeat earlier recommendations from their investigation into the collapse of the two large towers.

In both instances, investigators concluded that extreme heat caused some steel beams to lose strength, causing further failures throughout the buildings until the entire structure succumbed.

The recommendations include building skyscrapers with stronger connections and framing systems to resist the effects of thermal expansion, and structural systems designed to prevent damage to one part of a building from spreading to other parts.

A spokeswoman for the leaseholder of the World Trade Center, developer Larry Silverstein, praised the government's work.

"Hopefully this thorough report puts to rest the various 9/11 conspiracy theories, which dishonor the men and women who lost their lives on that terrible day," said Silverstein spokeswoman Dara McQuillen.

In discussing the findings, the investigator Sunder acknowledged that some may still not be convinced, but insisted the science behind their findings is "incredibly conclusive."

"The public should really recognize the science is really behind what we have said," he said, adding: "The obvious stares you in the face."

United 93 is all the proof we need 9/11 wasn`t a conspiracy, especially the on board cell phone call of one brave and heroic passenger who found a bit of humor knowing he might not make it but was going to stop that plane from hitting the White House. Americans step up when its all on the line, again and again!

watch the footage of WTC7 ? it''s na textbook controlled demolition - the owner of the WTC (Mr. Larry Silverstein, who only owned the Twin Towers for 50 days before he collected his $7 billion insurance settlement) admitted on film (PBS documentary) that WTC7 was "pulled" i.e. demolished .. even the BBC announced it''s collapse 20 minutes before it happened - prescient, since a steel frame skyscraper had never collapsed due to fire before, ever ... ahahahahahahah - such an inside job - it would be funny only if 3000 innocent Americans weren''t needlessly sacrificed for the neocon cause -

EXCELLENT IDEA. Anyone who believes this ridiculous story about fire imploding Building 7 (go watch the planned demolition pictures), also must believe the equally ridiculous government conspiracy theory about Saudi terrorists confusing the entire United States intelligence and military community.

Conspiracy or not something is wrong with this picture. Either these buildings were built in some flawed manner (see Irwin Allen''s Towering Inferno) or something else happened. I''m sure Silverstein is completely happy since he had the foresight to ink billions in insurance coverage just 2 months before these buildings came down. And I suppose that it is just coincidence that the only 3 steel superstructure buildings to ever collapse in this manner due to "fire" all happened within hours of one another.

Move along sheeple, uh, I mean people, nothing to see or read here.

I guess ProIsrael (must be a right wing extremist to support a terrorist country) has not seen the architectural drawings of the twin towers that show a maze 0f 110 story steel beams on the inside. They also did not see the photographs of steel beams cut at 45 degree angles and melted. It is not a question of whether these buildings were planned demolitions but WHO did it?

First time ever that a 747 flew into a building with a full gas tank! Think people! Do have you any idea the heat and explosive intensity of that? Slamming into a building going hundreds of miles an hour?! That would be enough to collapse any building, even the WTC towers and WTC7. Give me a break? Conspiracy theories?! The only conspiracy theory here is the fact that people can''t face reality and accept that civilians for the first time on American soil were attacked by an outside force. Was Pearl Harbor a conspiracy too?! It was a terrible, terrible day in American history, but to dishonor the facts is to dishonor the memories and lives of the THOUSANDS who died that day.

Conspiracy?

Let me get this straight...the same government personnel that routinely screw up foreign policy, domestic policy, personal infidelity, etc. that cannot seem to ever get anything right somehow pull of this massive hoax at the Pentagon, WTC, Building 7 during 9/11?

Come on, think about it. I mean REALLY think about it. Name ONE government official that you think have the intelligence to come up with something so complex AND pull it off? Even Wolfowitz who cooked up the middle east strategy with Iraq got caught *** around at the World Bank.

Please.

Knuckleheads like me4prezz must also think that if you are against the illegal and un-necessary invasion of Iraq based on lies that you dishonor the troops. Really, grow a brain.

me4prezz is the one who is in denial that the government probably planned and carried out the demolitions of the WTC. Why else would they hide the evidence, lie about the environmental effects and then not properly investigate it immediately. Grow a brain, please.

No, I do not believe the conspiracy theories. But I do take issue with the statement that no government official is smart enough to think up something like that. There IS one man......Cheney

To proisrael

"Most of American society before the Pearl Harbor bombing believed in the idea of isolationism. Franklin D. Roosevelt knew this, and knew the only way in which United States countrymen would take arms and fight in Europe%u2019s War was to be an overt action against the United States by a member of the Axis Power.

On 7 October 1940, Lieutenant Commander Arthur H. McCollum, head of the Far East desk of the Office of Naval Intelligence, wrote the eight-action memo. This memo outlined eight different steps the United States could do that he predicted would lead to an attack by Japan on the United States. The day after this memo was giving to Franklin D. Roosevelt, he began to implement these steps. By the time that Japan finally attacked the United States at Pearl Harbor on 7 December 1941, all eight steps had occurred."

After Churchill informs him that he has intelligence reports that indicate the Japanese are planning an attack on Pearl Harbor, Roosevelt says,

"%u2018I will have to consider the entire problem.... A Japanese attack on us, which would result in war between%u2014and certainly you as well%u2014would certainly fulfill two of the most important requirements of our policy.%u2019 Roosevelt speaks about absenting himself from the White House on some pretext, adding, %u2018What I don''t know, can''t hurt me and I cannot understand messages at a distance''."

How does questioning the means of collapse of the building "dishonor" the people who died there? Sounds like an attempt to shut people up and discourage them from asking questions. I don''t know who is right in this matter, but it does seem strange to a lot of people that the building was not hit by an airplane, and yet collapsed quite a few hours after the main buildings did. I suspect we''ll never know the real truth.

We''ll never know the real truth about anything (unless of course you believe in an afterlife....maybe then). Conspiracy theorists realize that we are in the Matrix, and we will never know reality while we''re here --- only what "they" want us to know.

More BS.

The building dropped -perfectly- on all four corners just like a controlled demolition. Look at any video of it and you will know what I''m talking about....if you can still find one on the internet, as the government made sure to ban all footage of WTC7 after it happened.

The AE911Truth tele-conference will follow immediately after the NIST (National Institute for Standards & Technology) slide presentation and Q&A of their WTC 7 Final Report which will be Webcast beginning at 8am PDT / 11am EDT. See the NIST webcast announcement & details here (and below).

In our AE911Truth response we will be documenting major flaws in the NIST report as well as the most serious omissions such as the collapse features of WTC 7 and the scientific forensic evidence of its explosive controlled demolition.

The subject is the collapse of World Trade Center Building 7 which was a 47-story, steel-framed, fire-proofed high-rise %u2014 the 3rd tower to fall straight down symmetrically at nearly free-fall speed on 9/11/01 with numerous reports of explosions and several tons of molten metal found in the basement carrying the "thermite fingerprint".

12. Did the NIST investigation look for evidence of the WTC towers being brought down by controlled demolition? Was the steel tested for explosives or thermite residues? The combination of thermite and sulfur (called thermate) "slices through steel like a hot knife through butter."

NIST did not test for the residue of these compounds in the steel.

As a contractor who deals with various building methods, I believe the buildings were all brought down by controlled detonations. They all fell precisely into the own foot prints.
That jsut does not happen in a fire...ever. After a plane hit the Empire State building all buildings by Code were built to withstand a direct hit from an airliner. That is a fact.
