That doesn’t address the point I was making since I was talking about the “they let it happen” narrative

I realize you were talking about a smoking gun for a different theory, but I couldn't help but introduce what I think is the most important piece of evidence in this whole saga.

I gotta say as a gut reaction that looks like a dicey source and I find any controlled demolition claims pretty laughable

Gut reactions can be helpful discriminators in some situations, but they are no replacement for in-depth critical examination, and they can sometimes be psychological defense mechanisms.

The source is a pretty detailed and comprehensive scientific paper. It's an open journal which means no peer review, so you have to study it and judge the quality of the evidence for yourself (homework, bleh!). I have some expertise in the field and I read the whole thing looking for obvious oversights and I was honestly shocked at how strong the evidence was.

Here's why it was compelling to me: nanothermite consists of nanometer scale particles of iron oxide and elemental (reduced) aluminum that have been intimately mixed together to allow a tiny gap between each and every particle. The only way to create this is to mix them together in a liquid suspension and then add a gelling agent to solidify the mixture and lock the particles in position, ready for ignition. It's extremely difficult to create because of the scales involved, so it requires a military-grade lab. It's not something that could be accidentally created in an explosion.

The authors found tiny magnetic chips (about 0.1 to 1mm across) in the debris, which looked like paint chips. They cracked them open to examine a clean part on their inside. They took photographs of it with an electron microscope, and used X-ray spectroscopy to analyze the chemical composition and they found that the red layer of the chips were made of spheres of iron oxide about 50 nm across and rectangular plates of reduced aluminum 100 nm long that had been mixed together and suspended in a solid organic matrix.

They also took the chips and put them in a calorimeter to measure their exortherms, and confirmed that they had the same explosive properties as laboratory nanothermite, so there's no doubt about its destructive ability. It was literally undetonated chips of nanothermite, and they found them in each of the four locations that were sampled, and in a relative quantity that would correspond to several tons in all of the debris.

that notion is completely undermined by the fact that the majority of the hijackers were from saudi arabia and the united states and the entire media did damn near everything they could to avoid addressing that inconvenient truth.

I said that 9/11 was to engender a fear of Muslims. The media did not avoid addressing the fact that they were Muslim. If anything, it was played up. Their nationalities were played down.
