STRUCTURE-RELATED NINE 11 POST: What really happened to World Trade Center 7?

I'm sure many of you know by now that Larry Silverstein received a call from the "er... fire department commander" to "pull" World Trade Center 7... but why? Silverstein Properties was the real estate contractor who first announced on April 26th, 2001 (Press Release) that they would enter into a 99-year lease agreement with the state of New York.

Silverstein is quoted as saying this in a 2002 PBS documentary:

"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 we watched the building collapse."

I don't think you can get any plainer... someone took that building down... but why? I'm not really into conspiracy theories, but why isn't it important to anyone what happened to WTC 7? I'm wondering how a building could enter into total collapse due to "fire" as suggested by the FEMA report. Why was it demolished?

Any thoughts on World Trade Center 7 should be posted here. I think it will be helpful to figure out what happened.
