"As described in Section 5.6.2, the sequence of the WTC 7 collapse is consistent with an initial failure that occurred internally in the lower floors on the east side of the building."
Further, on 5-16, it clearly states that WTC 1 debris damaged the front of WTC 7. When WTC 2 fell, it pretty much leveled WTC 5/6. When WTC 1 fell, it funneled part of that debris right towards WTC 7 severey damaging it.
The report you linked to clearly defines that damage and draws the conclusion that this damage and resulting fires brought down WTC 7.
No further conspiracy necessary.
Where else? They are all at Area 51 along with Elvis, Jimmy Hoffa, Osama bin Laden and the autopsied bodies of aliens.
Don't you know anything?
I wasn't insulting you as much as the way you are acting. But your reply was too funny! Do you want me to pound it up there so you can "pull it" out?
"My source" is the FEMA report.
The web archive link again is here for anyone wanting to read it themselves.

The damage is defined and not disputed by me on this thread. The collapse is still under investigation though. There were no conclusions in that report. Just more questions.
My source was your report. The damage was more than enough to drop the building. No conspiracy necessary.
Anyone can hit the link and read it themselves. It is not my report. It is FEMAs. And there are no conclusive statements in it.
They were blaring questions on the last page requiring more studies on what made the building fall.
Is this moonbat 'WTC demolition' hogwash welcome on FR?
Which is what I did. It just points out WTC 7 was heavily damaged when WTC 1/2 fell and that this is most likely what dropped it. The only particulars left unresolved are how much damage was done by the various gas lines, oil tanks, and power transformers in the building may have been damaged in the initial impact of WTC 1/2.
WTC 7 Collapse
CLAIM: Seven hours after the two towers fell, the 47-story WTC 7 collapsed. According to 911review.org: "The video clearly shows that it was not a collapse subsequent to a fire, but rather a controlled demolition: amongst the Internet investigators, the jury is in on this one."
FACT: Many conspiracy theorists point to FEMA's preliminary report, which said there was relatively light damage to WTC 7 prior to its collapse. With the benefit of more time and resources, NIST researchers now support the working hypothesis that WTC 7 was far more compromised by falling debris than the FEMA report indicated. "The most important thing we found was that there was, in fact, physical damage to the south face of building 7," NIST's Sunder tells PM. "On about a third of the face to the center and to the bottom--approximately 10 stories--about 25 percent of the depth of the building was scooped out." NIST also discovered previously undocumented damage to WTC 7's upper stories and its southwest corner.
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.
The Katherine Smith case ... the creation of fake identities for Jihadis. I always wonder about that, and I think that if one knew the full story, it would explain a lot about 9/11. She was murdered to shut her mouth, and we have never been given a proper explanation of the whole case.
Thanks for the additional information about the "plumber" who was working on the buildings.
We don't. You can have firefighters working a building fire without being IN the building.
