OK, so which bit were you contesting? I summarised Frank Greening's position as a request to NIST to check their working. He didn't appear to contest that because he didn't reply. I didn't have anything else to say so I left the thread. In what way is any of that "hardly what happened"?
When you want to tell somebody they've got something wrong, it's a good idea to wait till they actually get something wrong first.

You didn't summarize Greening's position in a single sentence. You didn't address the many valid criticisms that he raised in his post. You took one pot shot and ran back to the comfy confines of jref, where personal attacks pass as discourse.
Did you notice how productive and thorough that discussion was, even though it wasn't a consensus?
Here's a summary of what you avoided and Greening proposes:
Several aspects of NIST’s simulation “appear to be quite arbitrary and unphysical,” specifically, ignition time of the fire on floor 12; fire intensities and duration; overestimation of the heating of the structural steel; the low temps at which structural steel failures occur; the disparity between actual video images of the final moments of WTC 7 and Fig. 12-69 of NCSTAR 1-9, which, according to Greening, “look nothing like the video images of the real thing.”
Concluding, Greening suggests that NIST’s collapse hypothesis is “not physically realistic and is not well supported by observations of the behavior of Building 7 during its collapse,” and he calls for an alternative hypothesis.
