Here's what I don't understand about the NIST: why won't they release the raw data for their computer models so that independent researchers can verify their simulation? Science is literally about being as open as possible. It would be in their interest to better communicate their knowledge to the public and put these theories to rest. They claim that releasing the data would be a threat to "national security". Is that really true? How does knowing how to demolish a building which no longer exists pose a threat? In order to prevent a 9/11, all you have to do is secure the airplanes, which they've already done.
