Everyone was thinking "it was a controlled demolition" or talking about Lazer beams, trying to explain that the plane was edited in, maybe the towers never even existed and were invented by the media. But in reality it was a lot simpler, the Saudis sent people to fly planes into towers. Was the "jet fuel can't melt steel beams", like, purposeful misdirection or were conspiracy theorists just too imaginative for their own good
Building no 7 is kinda amazing. It might have a very reasonable explanation too but why did this other building beside it just collapse can seem mind-boggling at first glance.
Anyway the more interesting stuff is the speed with which Cheney and Bush took advantage of it and also the anthrax attacks which followed so soon after (which really helped turn the tide in the Senate towards passing the Patriot Act IIRC).
Edit: Oh and building 7 literally hosting CIA offices surely doesn't help people retain their sanity points
If I'm remembering right from the WTYP podcast, Building 7 was engineered with the corners of the building being major load-bearing structures, so when one of the corners of the building got taken out by a large piece of debris, it caused the rest of the building to rapidly collapse. Might be misremembering that, though.

The guy the FBI blamed for Amerithrax (not the first guy, who the press latched on to but was later exonerated, but Bruce Ivins) killed himself and the investigation only ever found circumstancial evidence with no clear motive (although they did accuse him of being a cross dresser).
