Dave, I addressed that question to you for two reasons:
1) Your background in physics (that is where my education lies also).
2) Your intriguing comment about me to R Mackey at JREF when I addressed the same question to him and recorded his response (after double-checking that his response was complete) in this forum.
Both of yourselves imply that you have some expertise in answering physical questions concerning the WTC collapses. I wanted to see that expertise displayed and that is why I addressed this question to you (and specified you answer be based in physics).
Unless you have something more to add, I believe we have seen the limits of such expertise.
