UFO Sightings

More than 130,000 pages of Air Force UFO files are now online. Air Force Times reports UFO enthusiast John Greenewald posted records from Project Blue Book on his online database, called "The Black Vault." 

The Blue Book contains Air Force files on UFO sightings and investigations. The Air Force recorded more than 12,000 sightings of strange phenomena in the 1950s and 60s. But it stopped investigations after concluding that the sightings didn't pose a threat to national security. 

Greenewald spent nearly 20 years filing Freedom of Information Act requests for government data on UFOs. He says his webpage is the first time the files are posted online in a searchable database.
