There are so many red flags and almost nothing has been explained in a way that doesn't involve unlikely coincidences.
If you are actually objective and not trying to fit missing pieces in to make the official story work i don't see how it can be believed. Reptilians is silly, the perps are sort of human.
It's not a stretch to think the others involved in the plot were put on the planes. As for keeping it secret many people are too patriotic to believe the truth and if it was told would pass it off as a lie.
There must be a lot of people who know at least one aspect is not true. The airline staff who checked correct passenger lists , the rescue workers in the buildings, building designers, anybody with common sense.
