Somehow, I suspect the FBI/CIA info may not be amongst the info released. Probably no joy on UFOs either.
Misplaced, perhaps?
Some astronauts have spoken on the record about UFOs and aliens, but a lot of that has been covered up/censored/under-reported.
Apparently during the moon landings, several UFO were sitting on the rim of one of the craters, and the aliens were watching our progress. We know it wasn't the Russians, Chinese, or other nationalities.
That radio transmission was quickly cut, and switched to another channel, according to at least one astronaut that landed on the moon, and amateur radio operators that were able to listen in on the other frequency as well.
IIRC, some minister, or other high level Canadian politician confirmed UFO/alien sightings.
Additionally, there are reports some of our nuclear missiles were destroyed by aliens during testing, and they've hovered over many of our ICBM bases and turned stuff off/disabled the weapons as well.
I also read one report where everything was turned on too, during an incident like that, but they eventually were able to shut the weapon(s) down. I suspect if true, that would be even more frightening, since having the aliens activate ballistic missiles is far worse than having them turn them off.
