The problem I have with these types of shows is that I'm not an engineer. I have one group of engineers telling me its impossible for the building to collapse the way it did then another group saying its entirely possible. How do I know which one is right?
I think the use of explosives is highly questionable and likely improbably though. If they were going to use explosives to bring it down in a controlled manner, one would think they would have hid it.
