I'll let others discuss this misuse of NFPA 921, but do a search in this forum for that term. In short, it's improper to cite it here.
And let's also remember that chemical testing for explosives has the strong potential to be inconclusive. How would there be any chance of distinguishing between explosives remains and naturally occuring organic materials combustoin residue from the fires themselves?
Whatever destroyed those massive structures so systematically must also have been present in the towers to such a degree that any proper, thorough, and unbiased, forensic analysis would have uncovered the necessay facts to know what actually occurred.
As it is, with the immediate disposal of the unexamined steel, and the media cover-up (see: Project Censored) there is still a very substantial body of damning evidence.
Besides, in this case the empirical evidence is so overwhelming I would not even need such an analysis to be 100% certain that explosives were used here. I don't know or care about thermite.
Try addressing the facts that are irreconcilable w/the official myth.
Is it also characterized by extremely loud sounds that would have the effect of shattering glass for blocks around -
The sounds? A Massive roar for 15 seconds..Thousands of explosions blurring into one prolonged event.
Read the Oral Histories for goddness sakes/// IT WAS VERY LOUD!!!! -
Listen to the audio on closeup vids.
Glass was shattered for hundreds of feet, everything was shattered,. the towers completely blown apart! The sound and later energy was tremendous - looks what remained of the buildings!
WTC7 was well over 300 feet away from the North Tower and it's collapse is blamed on damage created by N Tower's collapse (and fires having burned uncontrollably in offices for 7hrs)
Please see witness and WTC7 blast survivor (before the towers fell) long time NY City employee Barry Jennings

HOW DO YOU DISMISS THAT? I guess ike everything, buy getting hung up on minutia.
recall, a common preparatory procedure for actual explosives demolitions is to board up or otherwise protect (or remove) glass in neighboring buildings. Look at pictures of the Winter Garden's building across the street from the WTC complex for proof that no explosions occurred; what windows were broken were from falling debris. Explosions strong enough to drop the towers would have shattered all that glass.
Furthermore, it is a practice to remove people from the area in order to prevent injury from flying debris as well as barotrauma. For the latter, I've not found any studies indicating any numbers of barotraumatic injuries consistent with an explosion of even the size of the Madrid bombings or Israeli bus bombings, let alone for something as large what would be required for collapsing the Twin Towers, or even just 7 World Trade.
On top of that, you need to study the failure modes for the recovered steel components in NCSTAR 1-3C. None of them are consistent with explosives or incendiaries use.
If you study the legitimate research on nanothermite, you'll see that it's explosive properties are on the microscopic scale. For example, to force drugs past cell membranes. Or to achieve some result in the manufacture of microchips. Stating that nanothermite has high order explosive ability on the magnitude claimed here is unsupported.
On top of that, as pointed out earlier, all evidence contradicts the presence of explosives.
if you say so.
