Reply #3: Hoffman says it's for mechanical demolition, not explosive

[KJF]

He says a builing is "pulled" when cables are used to "literally pull down portions of the building."

I think this is right. If Silverstein meant "destroy the building" by "pull it" then he used the term inexpertly - assuming he knew the method of destruction beforehand (although you might not want to assume that). However, AFAIK he wasn't an expert in explosive demolition. Here's his article at Wikipedia:

I don't see any reference there to him having experience in demolition. Although that's not necessary comprehensive, maybe the guy did a blaster's course before he got rich, or just for the sheer hell of it.

My experience is that laymen sometimes use "specialist terms" in a slightly incorrect manner, so maybe he did in this case. I find it hard to say for sure. It'd be nice to find out the timing of the call, wouldn't it?
