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!
