The jet fuel burning steal beams is an interesting one. I remember, perhaps weeks after the event, if not days, scientists being interviewed on national news explaining the science about this and being very clear that this was certainly plausible - it wasn't just the jet fuel but the surrounding materials and chimney like effect of the building which increased the fire's temperature (don't quote me on these details).

How it became the most prominent conspiracy theory is wild to me. Not dissimilar from a random xenophobic Facebook post about illegal immigrants eat pets becoming a major talking point during a presidential debate. Or how it was verified that the 2020 election was the most secure in our nation's history yet more than half of Americans believe voter fraud is a serious threat.

As you've pointed out, that's just a fraction of the "coincidences" surrounding this event. Individually, I could understand they'd be forgotten or swept under the rug but as a whole, it's just a lot of stuff to swallow if you want to believe the "official" report. At the same time, I acknowledge that for this many "coincidences" to be planned out would probably be impossible to cover up.

In comparison, consider what's know and still covered up about the JFK assassination. This is relatively small potatoes in scale compared to 9/11.
