I just finished a book by journalist Annie Jacobsen about the history of "dreamland" called AREA 51: An Uncensored History of America's Top Secret Military Base. There is a lot to cover in this book but I just want to bring into focus one aspect. Spoiler Warning: Ultimately the theory we are left with is that the alleged extraterrestrial U.F.O. that crashed near Roswell, NM on July 2nd 1947 (including alien bodies) were in fact Russian made and designed. It was purposeful. Stalin was a master of psychological warfare and he approved a plan to scare Americans with a faux alien invasion event to capitalize on the U.F.O. hype that was building up in the news. After all, who could forget the panic that ensued after the War of The Worlds radio broadcast in 1938. The timing was perfect to send his fake U.F.O. into U.S. airspace right after the Kenneth Arnold report of flying saucers. Stalin wanted to create panic. So after the war he somehow manipulated Nazi Joseph Mengele - who by then had already fled to South America - to create deformed humans with large heads and large eyes so as to look like aliens. The deformed people were allegedly children and diminutive in size. In the book it is suggested that Russia had already perfected a craft that did not rely on the usual means of propulsion, and somehow harnessed electromagnetic energy to hover and move through air space virtually undetected. However, this craft with amazing capabilities which was and still is light years ahead was somehow based off of the Horten brothers' designs of a very innovative airplane using concepts of aerodynamics - not anti-gravity. It also must have had stunning stealth capabilities, but as you can see in this article, known stealth development was still very primitive, even in Germany. So all of that's quite a leap.
Second, for the sake of possibly creating some unmeasurable amount of panic in America, was Stalin really willing to risk sending this super tech into our space without years of testing and perfecting? Why rush? I mean, if he had anti-gravity technology, he could have expanded to take over a multitude of territories with ease. Perhaps including the moon and beyond. The military advantage of this kind of technology could have been the ultimate checkmate on the United States. But instead he wanted to scare us a little. Hm. The aftermath of The War of The Worlds broadcast was not neat and tidy, and it did have a negative effect, but it certainly didn't destroy the fabric of America. Mobs of people weren't running in the streets. One must also consider, that America had since just come out of a war which hardened most them whom had become accustom to adaptation for their own survival and for the greater good of the U.S.A. Stalin must have known that a little scare tactic of fake extraterrestrials and a flying saucer wasn't going to be enough to unnerve the majority of the public. Especially knowing our government would have intervened either way. So did Stalin really think he could panic the our military so easily?
Lastly, if indeed Stalin was absolutely resolved on creating panic at the risk of exposing his science-fiction level technology (far more valuable than anything else), why did he choose the middle of a desert to reveal his master show? Yes, that's where the most secret military bases were. However, using this craft to collect intel on the Nevada Test Site would have been a separate mission with well trained pilots (remotely or on board) and certainly without the need these allegedly deformed and tortured children. It doesn't make sense to crash land purposely in a place where the government could more easily cover it up. I should think they would have chosen the White House lawn.
If they intended to crash so we may see the fake alien bodies and have the news media perpetuate the story, even when the Army moved to retract its original statement (being it was a crashed UFO of other worldly origin), why didn't the Russian operatives in the U.S. move to stoke the event and keep the story alive? We know Russia had operatives and spies in America. If this were all true, Russian operatives would have been watching closely.
Lastly, by purposely crash landing an anti-gravity craft to trick our military or the public into believing aliens exist, Russia was therefore willing to hand over this astounding technology. Literally giving us a gift to reverse engineer. To my mind, it simply does not add up.
