I understand that to be the case as well. However, Im not willing to reject the notion that a crack, highly trained team of specialists could've rigged WTC7 in an emergency hoping to merely mitigate the damage from its collapse and 'getting lucky.' Far stranger things happen. As a trained firefighter, I can see how it could be done if the situation were dire enough and the team had big enough cojones. ...I don't think it necessary was that dire that WTC7 be demo'd, but I wasn't there.
