Since the CIA has just dumped millions of files online for you all to look at, I just picked one at random. I don't know if this is one of their new dumps or not as it could be part of the old database. https://www.cia.gov/library/readingroom/docs/DOC_0000098713.pdf

Seems interesting, although not a lot of detail apart from it was a pulsating orb, so say the Police Officers.
