Here's a post
I'm working on for SLC. We often hear about how the speed of the WTC Towers' collapses indicates controlled demolition, so I thought I'd take a look at the speed of a real CD where we know the height of the building. To my surprise, I discovered that the WTC came down too fast for controlled demolition.
Comments? I don't have any illusions about this proving anything; for one thing I don't buy the 8 and 10 seconds cited by CTers and the 9-11 Commission for the collapse times. It's just another example of how even the evidence the Truthers cite doesn't show what they think it shows.
