The British Ministry of Defense is releasing its formerly classified files on UFOs. A really fun site from the British National Archives has the files available for download, along with a hilarious quotation by Churchill—"What does all this stuff about flying saucers amount to? What can it mean? What is the truth?" There's also a video from Nick Pope, a former MOD UFO investigator who's described, confusingly, as an "expert on the unexplained."
