With over 100 years of building steel-framed buildings not once in the history of man has such an event taken place, fires have never caused the collapse of a single one, and you will not find another example of this happening with the exception of WTC 1 & 2 of course.

FEMA's explanation was fire collapsed the building but also said this explanation had a low probability, and also admitted to being clueless about how fires actually caused the collapse.

NIST said (2005) that a ¼ of the building was missing due to falling debris and that caused the collapse along with fire, however it has to be said how can the remaining ¾ totally collapse equally to even replicate what we can see during the video, let alone the many clips showing a complete building.

The importance of building 7 is huge because by scientific standards it is a definite Controlled Demolition, and this is critical because anyone in the demolitions business will tell you it takes weeks to prep a building, not hours.

WTC 7 collapsed in 6.5 seconds at 5:20pm on 9/11. Multiple emergency workers reported a countdown over the radios immediately preceding the collapse. Witnesses to the collapse heard numerous explosions and saw a "shockwave ripping through the building". One high profile witness recounted explosions in the lower floors of Building Seven before either of the Twin Towers collapsed.

This would ultimately imply that building was rigged to implode before 9/11, and therefore a gaping hole in the official story as I'm sure even Osama couldn't pull off wiring up such a building housing the most important fringes of the Government:

Secret Service, the Department of Defense, the Immigration and Naturalization Service, the Securities and Exchange Commission (SEC), the Mayor's Office of Emergency Management, the Internal Revenue Service Regional Council (IRS), and the Central Intelligence Agency (CIA).

Interestingly this is what Larry Silverstein had to say about the collapse to PBS:
"I remember getting a call from the fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, 'We've had such terrible loss of life, maybe the smartest thing to do is pull it.' And they made that decision to pull and then we watched the building collapse."
