That would depend on what the fire department meant when it used the expression. I neither believe nor dis-believe, based on the statement. What do you believe? We’re talking about Building 7, not the twin towers the planes hit.
The documentary went over this issue about WTC-7 and Silverstein’s comment. I think it is utterly clear (and Silverstein has confirmed) that what he meant by ‘pull’ was that he agreed it was best to ‘pull’ remaining firefighters away from WTC-7 due to the danger of collapse.
The nutters are still making me sick - every nonsensical point they make has been amply refuted - they have some psychological need to believe total nonsense.
