I don't know how you can say that with so little information. NIST didn't address the question of spherical iron particles in the dust. Other reports say those particles are to be expected. There may well be conditions that would produce the particles without invalidating NIST's conclusions. It seems to me that much more study would be needed to reach any conclusions about this issue.
The fire test data is what throws Nist off, although I agree that fires did cause them Nist reported fire models are simply 400c to low to do it. That means that the models are off by 400c and they were not caused in a hydrocarbon fire.
Most of the reports also were made when the Chimney-jet burner effect or the Aluminum burning effect was the current theory of the fires intensity. Nist back away from those theories. However the reports were not modified to take in the change in temperature drop when the Chimney effect was abandoned, in the twin towers, the reports were not modified to reflect real world conditions, as by NIST data.
Except in the part of the production of the molten material dripping from the towers in a chimney effect in the air handling system.
There is however not enough galvanized steel in the air handling system to account for them.
It is a real mystery, and Dr. Greening hopes to solve it, and the reason the concrete was so easy to break I believe.
I simply see a mystery here that Nist left unsolved, and am looking for reasonable answer to it, if you read the physorg discussion Dr. Greening was in contact with the scientist, who produced the reports they described a fuel layer.
I have contacted a witness who because of the truthers does not want his name used publicly and he described a strange blue flame coming from lifted pieces of concrete at the site.
I do not know what the researchers told Dr. Greening but the blue flame is indicative of possible, but not conclusive sulfur reactions.
I would prefer to let Dr. Greening take it from here when he wishes, I do not presume or do I wish to talk for him.
One thing I should point out, is there is no aluminum oxide in the samples that I can see associated with the iron and zinc so it is not a thermate-thermite reaction.
Although a natural aluminum reaction Could produce steel hot enough to degass carbon the particles do not appear to be the result of a direct thermate reaction.
