( CNN ) It 's enough to make Mulder and Scully seethe with envy . Nearly 130,000 pages of declassified Air Force files on UFO investigations and sightings are now available in one place online . Declassified government records about UFOs have long existed on microfilm in the National Archives in Washington , DC . Many of them also live on websites devoted to the topic , sometimes free , sometimes not . But UFO enthusiast John Greenewald says his database , Project Blue Book Collection , is the first to compile every single declassified document from the Blue Book project -- headquartered at Wright-Patterson Air Force Base in Ohio from 1947 to 1969 -- in one place for anyone to search or download for free . The collection consists of files from Project Blue Book , Project Sign and Project Grudge , the names given to official investigations into unidentified flying objects by the United States military . Greenewald 's efforts are not motivated by a close encounter or personal experience with unidentified flying objects . He says he 's just driven by curiosity . `` I 'm a history buff . I think this stuff should be accessible , '' he said . `` Secrets are not bad things ; I think we should know about this and it should be in history books . '' Greenewald started requesting information related to Project Blue Book through the Freedom of Information Act 15 years ago . His interest was piqued by the first case he received information on about a 1970 UFO incident in Iran , after Project Blue Book ended . `` It defied explanation , '' he said , `` and 5,000 FOIAs later my curiosity has n't gone away . '' The collection contains 10,000 PDFs , each representing a different case . The files include the details of some of the most famous UFO cases , including the Exeter incident , the Kenneth Arnold sighting and the Mantell crash . Still , Greenewald believes the contents are `` just the tip of the iceberg . '' `` It 's all a puzzle , '' he said . `` Just when you think you 've got all the pieces to make a picture , you realize it 's only a piece of a bigger puzzle . '' The Blue Book project was discontinued after a joint review concluded that no significant information had come from it , according to declassified documents on the National Archives website . Specifically , the review said no UFO `` reported , investigated and evaluated '' ever gave `` any indication of threat to our national security . '' Nor did the investigations suggest that the sightings `` represent technological developments or principles beyond the range of present-day scientific knowledge , '' a 1985 Wright-Patterson fact sheet said . `` Since Project BLUE BOOK was closed , nothing has happened to indicate that the Air Force ought to resume investigating UFOs . '' Greenewald is not so sure -- especially not after viewing all the documents , which are full of blacked-out material . If the U.S. military ca n't identify some unidentified flying objects , then who can , he wonders ? And what are they ? `` The biggest takeaway for me is do n't believe the company line , '' he said . `` I think something big is going on . How big , I do n't think anyone will know for quite some time because government continues to make the rules . `` It 's a hard game to when they make the rules and they 're the referee . ''
Project Blue Book Collection contains nearly 1000 pages of research into UFOs . Project Blue Book , based in Ohio , operated from 1965 to 1969 . The documents were published in one place online for the first time .
