Mmgh, more like a little Hollywood with some truth mixed in there. Was said in George Answers book Extraterrestrials Among Us, that it was PAWTAS a style of extra strong radar to keep nabs on post world war two aircraft, that was causing the flying saucer to fall out of the sky. The technical was, that the increase in microwave strength was short circuiting the covering plasma sheath on the outside of the saucers and they were falling out of the sky.Is this true?
Lots of UFO crashes, not just one. Some' even in Mexico and the Mexican government let us have them, because they were illequiped to handle all the accessories captured with the saucers.
Know in time this went on in technology to the Russian Siberian frontier, to where big radar gates were constructed and from the feedback is hundreds of saucers were downed. Of these were near modern day Pleiadean saucers and the Pleiadeans were it was said, hopping mad. They wanted their people back.
Russians don't really give a good crap about anything, so the probable answer to your next question is, they kept them. Have no idea as to what happened to the Pleiadeans once they were hosted by the Russians? Maybe working as waiters waitresses in some Russ restaurants.
In Andrews books take your time reading them because he gives lots and lots of details, with his books. And if you can go to a lot of the online book houses and enter in the search words, (Authors whos materials is very similar to George C Andrews)?
Andrews was one of a kind. I laughed when in his second of the ET series he told of a ball shaped spy-bee monitor craft being spray painted blind in one of these underground bases. "Smashed into a wall). The Falcon 9 launch vehicle that blew up, "oh how did that happen"?!!
I think the use to take the UFO drivers to Ohio in a base beneath of Wright Patterson AFB. Prez. Nixon had taken actor Jackie Gleason down into one to show him a little alien. I mean who else is anyone want to take with him, but a stage actor entertainer?
Definitely keep your sense of humor about you wits when entering this territory. It's actually a prerequisite.
