Australia's defense department loses track of its UFO 'X-Files'

CANBERRA, Australia - Australia's military has lost its "X-Files", detailing sightings of unidentified flying objects (UFOs) across the country, a newspaper report said on Tuesday.

After a two-month search in response to a newspaper Freedom of Information (FOI) request, which forces government officials to release documents of public interest, Australia's Department of Defense had been unable to locate the files, the Sydney Morning Herald said.

"The files could not be located and Headquarters Air Command formally advised that this file is deemed lost," the department's FOI assistant director, Natalie Carpenter, told the paper. Defense officials could not be contacted.
