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
I think in this case (along with a lot of conspiracy theories) it's inventing the most fanciful, complex explanation in order to avoid any scrutiny of capitalism and imperialism
