I have stated why so many people compare the collapses of WTC 1, 2, 7 to controlled demolitions... and that is because the only other time in history where we have seen images of tall buildings falling/crumbling to the ground in seconds is during a CD. I have also stated that I don't think WTC 1, 2 or 7 were CD... but rather another type of "demolition." Make no mistake... they were demolitions, just not controlled demolitions by exact definition.
Now... people try to debunk the Silverstein...quote, of pulling WTC 7:

By saying that he was referring to the firefighter effort in WTC 7. (Even though reports show that the firefighters had already left WTC 7 earlier in the day... maybe because - gee, let's see... the other two buildings had already crumbled to the ground. Do you really think any firefighters stayed in WTC 7 after WTC 1 & 2 fell)
And, also by claiming that... "pull" or "pulling" isn't a term used in CD. Well... fair enough... but these three demolitions weren't CD, so that's not a completely accurate application of facts.
"Pulling," although, not commonly used when referring to a CD... is a widely recognized term used by demolition crews.
"(4) "demolition" means the act of
pulling down, destroying, removing, or razing a building or structure, in whole or in part (including the demolition of exterior walls or roof), or commencing such work with the intent of completing the same, all as determined by the building commissioner; provided, however, that the term "demolition" shall not include the ordinary maintenance or repair or an addition to any building or structure."

And, if you want real-world evidence of this term in use... than look no further than a demolition crew at ground zero, who says "Pull" in reference to demolishing WTC 6:

Some claim... that, 'pull it' is a term used by firefighters to signal the evacuation of a building. I have heard some firefighters say that this term originated many many years ago... and that, most of today's firefighters no longer use it.
I have also seen people make a point about - how would Silverstein know old firefighter terminology... and someone replied, he probably didn't... he was quoting the Fire Department Commander. But... that's not true, because Silverstein's exact words are:
[FONT=Verdana, Helvetica, sans-serif]
"I remember getting a call from the, uh, fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, 'You know we've had such terrible loss of life, maybe the smartest thing to do is, is pull it.' Uh, and they made that decision to pull and then we watched the building collapse."[/FONT]
