Well first of all let us bear in mind that what they say is not necessarily what it IS. ...
Those confirm that the temperatures were NOT anywhere near 1000 degrees.
Argue it if you like, you are arguing NIST and FEMA not me. You are arguing real science not me.
The statement was 'even NIST concluded temperatures did not reach temperatures high enough to melt aluminium.'
This is shown to be false by NIST's own statements on the matter. Simple.
The question of what the temperatures actually are, is a different one. Saying normal office fires don't reach higher temps, therefore because these fires were in an office, that proves they didn't reach higher temperatures, is really weak.
For one thing, what on earth was 'normal' about these 'office fires'?
