The truth is out there — and it's now on the web.

The fabled Project Blue Book, the Air Force's files on UFO sightings and investigations, have tantalized and frustrated extraterrestrial enthusiasts for decades. But this week, nearly 130,000 pages of declassified UFO records — a trove that would make Agent Fox Mulder's mouth water — hit the web.

UFO enthusiast John Greenewald has spent nearly two decades filing Freedom of Information Act requests for the government's files on UFOs and other phenomena. On Jan. 12, Greenewald posted the Blue Book files — as well as files on Blue Book's 1940s-era predecessors, Project Sign and Project Grudge — on his online database, The Black Vault.

Project Blue Book was based at Wright-Patterson Air Force Base in Ohio. Between 1947 and 1969, the Air Force recorded 12,618 sightings of strange phenomena -- 701 of which remain "unidentified."

According to a 1985 fact sheet from Wright-Patterson, posted online by the National Archives, the Air Force decided to discontinue UFO investigations after concluding that "no UFO reported, investigated and evaluated by the Air Force has ever given any indication of threat to our national security [and] there has been no evidence indicating that sightings categorized as 'unidentified' are extraterrestrial vehicles." Wright-Patterson also said the Air Force has not seen any evidence suggesting the sightings "represent technological developments or principles beyond the range of present-day scientific knowledge."
