Derek, while I appreciate your replies, you seem to be missing my point - and it's the same point others are making. I want you to tell me why these three questions are important.
If there was molten steel, this implies something nefarious. Molten steel is impossible in an office fire, and there are plenty who are claiming they saw it. Can I connect the dots? Nope, so its a non issue to those who are emotionally attached debunking the 9-11 conspiracy. Was molten steel seen? It appears, and I still have not heard anyone clarify how it could even be there.
What do they mean for the collapse of the WTC buildings? I'm not a construction professional, but I'd say there's been an answer to your question no. 1. You might not like it, but it's been answered in this thread and in numerous others.
Like I said, these are the questions that keep comin up over and over and keep getting answered over and over. I look around at the engineering research community and I don't see anyone asking these questions about the collapse of the WTC buildings.
I do, and other structural engineers that I know very well do to. All we want it a decent IGES and a reasonable array of FEA surveys, and if NIST is right, better still.
I only see Truthers on JREF and Truther forums asking them - over and over and over again. It's kind of getting silly. Why do you think they're important?
TFK is to blame for me. I think the molten steel witness statements hold a possible mode of column manipulation. That is a hypothesis I could test via multiphysics FEA and about thousands of hours labor. I've been pushing Mr. Richard Gage to turn in this direction since 2007. Will this settle it once and for all? Then why not?
What do you think they say about the collapse? Why is it that only Truthers ask these questions and not faculty in the departments that research steel frame structures?

To the point of NIST's "new - first time ever" phenomena, "new" cause of total building destruction, "new" root cause, I have not seen the industry respond one IOTA to office fire thermal expansion walking girder woo. This was NIST's recommendation, yet everyone in my world is unaware ignoring it.
Never enter an mid to high rise building again, there might be a fire, and now we all know what that leads to:

Seems to me that NIST is reaching, and the closer I look at their material, the more frustrating their work seems to get. The models and "new" phenomena are just a starter. The lack of iterations in the FEA and the miniscule-to-NO FEA support of the 79 to 44 stress strain initiation survey makes me a little skeptical.
This alone should make anyone skeptical.
