The WTC micro powdered concrete etc.

[SHERITON HOTEL]

Seems like an obvious question but has anyone ever analysed the floors and other solid material of the twin towers that were reduced ,I'm informed, almost entirely to micro particle, positively or negatively for explosive residue? Is this possible?The clean up couldn't have been that complete, this evidence must still be on some people's, living or sadly dead, lungs.

Yes - some of the dust has been analysed:

Um, it was pretty nasty stuff.

Again this raises issues about the pulverisation - of steel, concrete, office materials, human bodies
Does our quite proven demolition explosive idea explain this fully
Radioisotopes found - well I suppose this might be explained away by domestic style fire detectors
A lot of humans seem to have been vaporised or at least to have been torn into tiny particles of tissue
The explosive demolitions theory - good for the most part, doesn't entirely explain this
