On the ground of UFO investigations this document is just a decent example how burreaucratic (red-tape style) institution is CIA:

This document is just big WOW. In 1950s CIA investigated the possibility that flying saucers could be the effects of genuine German science that somehow was overtaken by Soviets and further developed to threaten people in the United States, they investigated this issue in details, searching through who could work on aerodynamics in Germany that time and at what stage could finish their studies (theoretical and practical) etc. A very interesting document!

And this document – not easy to find – it is not at any of first pages of any catalogue. You need special keyword search patterns to find also such documents. I don’t know if there are many more of the same kind but today I found this and it turned out to be even more compelling as reveals different information, stories about how some technology development continued etc.

About flying saucers experiments
https://www.cia.gov/library/readingroom/docs/DOC_0005516188.pdf
And here worth to be analyzed is that on Wikipedia there are many sources-based article supporting that this was conspiracy theory and NO CIA document mentioned… Also no name of Klein… So they probably did not realize that among official CIA documents there are such „revelations”

I think that particularly this book is worth reading to balance brief CIA reports – Hitler Flying Saucers by Henry Stevens
Another resource of „free” kind:
The little Danish argument that flying saucers had been observed for some time in 50s as being dispatched from Soviet base in Arctic.
