Here is a video of Professor Jones of BYUniversity presenting a lecture about the collapse of the WTC buildings. He talks about the stresses on the steel columns imposed by the heat of the fires and how they were not great enough to cause the nearly free-fall collapse. Aside from the political implications of his lecture, which should not be discussed here, I am curious to hear what some of the physics experts here think about the scientific underpinnings of his lecture.

Please be objective and refrain from political comment, thanks.
