Although we should not condone hacking of Government Departments, it would be interesting if someone got into whatever department holds the UFO information.
The BBC has the story of John Greenewald who has spent the last two decades requesting declassified information from the US government regarding UFOs.
Although obscured with many redactions, he has amassed over 100,000 pages of documents from Project Blue Book, the files which show how the US Government investigated 12,618 UFO sightings until it was 'closed' in 1969.
In 11,917 cases the following investigation by the Project Blue Book team were deemed caused by weather balloons, swamp gases, meteorological events, temperature inversions or hoaxes.
In 701 cases, the Unidentified Flying Object remained unidentified and could not be explained even after stringent analysis.
Of course it doesn't mean that it was little green men popping by to see what we are up to or a reconnaissance mission by creatures from Alpha Centuri sussing out whether we are ripe to be invaded but it also doesn't mean it wasn't.
Cue the X-Files theme tune.
