From the link above:

Benjamin Chertoff, Researcher for Popular Mechanics, on Coast to Coast AM - March 5, 2005:

I'm glad somebody brought up the Larry Silverstein comment, because we certainly looked at that... What he says is "they decided to pull" which is referring to the fire department. And of course in some circles of the controlled demolition industry "Pull" is used to mean that you actually demolish a building.

Just over a year later, Popular Mechanics changes their story...

Davin Coburn, Researcher for Popular Mechanics, on The Charles Goyette Show - August 23, 2006:

Having spoken to any number of large controlled demolition firms... the term "Pull it" is not a demolition term... We have never heard it used that way and neither actually have the people who do this professionally that we spoke to.(More after jump...)

I'm confused. A researcher from PM publicly admits that "Pull" IS a controlled demolition term -- however, a year later another PM researcher explains that it's not...?

Well, from looking at the information below, it appears that someone from PM's "Research" department is lying...

Phone call from PUMPITOUT.COM to Controlled Demolitions Inc:

PUMPITOUT: Is this Controlled Demolitions?
CONTROLLED DEMOLITIONS INC: Yes it is.
PIO: Ok, I was wondering if there was someone I could talk to breifly just to just ask a question I had?
CDI: Well what kind of question?
PIO:I just wanted to know what a term meant in demolition terms.
CDI: Ok what type of term?
PIO: Well if you were in the demolition business and you said the term "Pull it", I was wondering exactly what that would mean?
CDI: "Pull it"?
PIO: Yeah.
CDI: Hmm. Hold on a minute.
PIO: Thank you.
CDI: Sir?
PIO: Yes.
CDI: Pull it is when they actually pull it down.
PIO: Oh, well thank you very much for your time.

And here's an excerpt from an interview with controlled demolition expert Danny Jowenko, who has almost twenty years experience performing CDs, also confirming that "Pull it" is a controlled demolition term:

This is work of man. This is a hired job. (Silverstein) said it himself. You hear him saying "Pull it" down.

I think it's long overdue that Mr. Silverstein get up in front of a courtroom under oath and explain exactly what he meant when he said...

I remember getting a call from the, er, 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.
