UFOs stories

Previously on DVICE, we examined once-secret FBI documents from the Bureau's investigations into freaky, unexplained phenomena. These glimpses into the real-life X-Files were made public via various Freedom of Information Act (FoIA) requests and subsequently posted for all to peruse on the agency's online "Vault". As it turns out, the FBI isn't the only government body with a history of investigating mysterious activity. FoIA-liberated documents from the Central Intelligence Agency show how America's stealthy strike force has had a keen interest in strange "aerial phenomena" from all around the world. We're talking UFOs!
Flying saucers are generally associated with UFOs, with that "U" in there standing for "unidentified." But the saucer shape isn't just limited to aliens from outer space: there are a fair number of entirely identified terrestrial aircraft that utilize a more or less circular and saucery design. We've got a list of ten flying saucers for you, each of which made it far enough out of someone's imagination that at the very least a proof of concept was constructed. No blurry pictures that may or may-not-be-streetlights here: these are all real designs that actually existed.
