All of the thermXte claims are technically ridiculous. Most of them several orders of magnitude outside the range of possibility:
...all the "silent explosive" stuff when explosive cutting depends on a ruddy great big "Bang";
...no way that use of termite melting could be incorporated into the global collapses of WTC 1,2 or 7 - cannot be synchronised as only one of the problems;
...not enough heat available from painted on thermXte
and that's technical reality before we even look to the logistic and security impossibilities of doing it without getting caught - before, at the time OR after.
And the truthers forget that the first thoughts of most engineers - particularly us military engineers - is
"How would I do it if the Boss/General gave me the task?"Give me a pristine WTC Twin Tower out in a desert to avoid "collateral damage" plus needed resources and I could easily bring it down..
...but no way could I mimic how the towers actually fell using thermxte and not revealing my tricks
...could probably mimic the collapse using conventional explosives BUT not without the "big bangs" OR visual give away evidence.
AND
...certainly not whilst integrating an aircraft impact scenario as part of the cover story.
