Came here by accident. Read the article, read the comments. Plenty opinion given, but none address the content / scope of the professor's study and findings. That is with the exception of, "NIST prepared a comprehensive evaluation of the collapse of WTC 7" ............. which has not been peer reviewed, nor the modelling data released. Unlike the UAF professor's data which is available to anyone to view and review. Maybe the opinionated should do so. Education is fundamentally founded on the principle of asking questions and searching for answers. I'd be concerned about a University which did not entertain such values. UAF obviously has no problem with the questions being asked whatever the outcome or opinion. Good educational footing that.
