In fact, there is documented evidence that the CIA will always hide the banal under the outlandish. When Bell was testing the US' first jet fighter, their pilots wore gorilla masks so that any observers not within the circle of trust would have to not only overcome the "I saw a plane flying faster than possible" hurdle, but also the "and it was being flown by a gorilla" hurdle. Project Mogul really was weather balloons with instrumentation to observe Soviet nuclear tests but within two days of one coming down in Roswell, it was little green men. There was a time when more than half of the board members of UFO organizations in the United States were CIA operatives. And once you remove all the previously-classified-but-now-documented U2 and A12 flights from Project Blue Book, all 12,618 "ufos" go away.I think the problem is dumb conspiracies are always outlandish and real conspiracies tend to be banal.
