From my earlier link:

As I've already pointed out, without violating the third law of motion, even two and a quarter seconds worth of free-fall would necessitate the removal of all resistance to the downward motion for that period of time.
NIST's explanation, which remained essentially unchanged from the first to its "final" incarnation, was that the building experienced a "progressive collapse" involving the interaction of building materials (read some degree of physical resistance) from start to finish.
In their own words:
"Progressive collapse is defined as the spread of local damage from a single initiating event, from structural element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The failure of WTC 7 was an example of a fire-induced progressive collapse."
Even granting the ridiculous notion that the building's "entire façade" could somehow remain standing intact as all of the internal structural beams were taken out 'progressively' like a trail of fallen dominoes (as opposed to simultaneously by some other means), the interacting materials in the façade itself would necessarily slow its descent, because concrete doesn't pulverize concrete without creating resistance either.
Physical progression "from structural element to element" is contingent on resistance. That means a "fire-induced progressive collapse" couldn't possibly have been the mechanism of free-fall. It also means NIST would have us believe that the laws of physics were violated for 2.25 seconds on 9/11; and that's something I simply can't accept with any degree of intellectual honesty.
Simple....... THEY WERE ALREADY IN PLACE LIKE THEY WERE IN THE TOWERS!!KevinWestern said:And secondly, if building 7 was brought down manually by the Fire Department how did they manage to get the explosives set, etc so quickly?
But no evidence of any mechanical device was found so unless you believe all those connected to the investigation are hiding something, we're gonna hafta go with what their findings. Do you have any evidence of or a theory about what brought down WTC7?

It is the CTers who insist that the entire WTC7 fell at freefall speed. I have shown through nothing more than common sense that it did not. You want to pretend that both are wrong because of physics that you can't prove.
And still we ignore that only a portion of the building (the North facing facade) ever hit freefall speed.
And we know that the interior of the building had already collapsed seconds ahead of that...
Here is an article to answer your question/observation that the collapse has never happened before, and why it did collapse: Debunking 9/11 Conspiracy Theories and Controlled Demolition - First Time In History
Thanks, Ive actually seen this before. All it does is assert that there were some things that never happened before with WTC 7 and therefore we are asked to accept the official report. Do you have anything that dives into the collapse itself more deeply?
WTC 7 had 47 giant steel beams that ran up and down the center of the building. Structural damage was only on the south end, and although we have many example of partial collapses due to fire (when speaking of steel skyscrapers) I dont know of any TOTAL building collapses to compare this with. Straight down!
80 perimeter columns and 24 core columns all gave way at the exact same time due to fire? 6 seconds. Do you have something that explains this off?
You sure do know of other buildings that more or less collapsed straight down, WTC 1and2. How many other buildings do you know of that have collapsed? I doubt many.
Any way here are some pictures and a video of a site that should not have an axe to grind. Note how intense the fires were: Footage that kills the conspiracy theories: Rare footage shows WTC 7 consumed by fire | Mail Online
Also the link I provided you made this statement: To put it simply, the building DID fall over backward and to the south-east. Just not like a steel reinforced concrete building would. Another telling photo is this one taken closer to the event date.
Which is not falling into its footprint. So I am not sure you looked at the evidence that was in the link.
Bottom line to me is, we know it was on fire, we know fire weakens steel, we know people could not have gone in and placed charges, and we know the result. Why exactly it fell as it did we may never know we just know it did.
