Remember, when you destroy buildings with explosives, all of the following cannot possibly be avoided:
- Preparatory work directly on the structural members that you are going to attack
- Incredibly loud BANGs
- Structural members (pieces of steel) that show peculiar failure modes which are not shear, bending, buckling
- Chemical residued that some of the sniffing dogs who worked the piles could have detected
- Residues of demolition equipment (det cords...) that the demolition professionals of at least 4 different demolition companies could have identified
None of 1. was observed
None of 2. was observed. All explosion sounds that anybody reported or even recorded were not of the kind, brisance, loudness and timing one could expect from demo charges. Not a single one.
None of 3. was observed.
None of 4. was observed.
None of 5. was observed.
There is precisely ZERO evidence for the use of explosives to demo any of the three towers. Not just the the lack of residues.
