ET beware – Irish military intelligence is keeping a wary eye out for any alien invasion.
Newly-released state files reveal that G2, the Defence Forces' secretive military intelligence unit, has been monitoring all reports of Unidentified Flying Objects (UFOs) over Ireland.
One file, updated in 1982, focused on sightings of suspected UFOs over Kerry, Meath, Dublin and Kildare.
The two major sightings listed were over Dublin Bay and the Macgillycuddy Reeks in Kerry.
The former involved a cigar-shaped object spotted by Dublin woman, Pat Laffan, over Howth's Lambay Island.
The RNLI said there were no marine flares fired that day.
The second incident was a group of glittering objects, all flying in a V-formation, spotted by a pilot and his five passengers as they flew from Farranfore to Dublin.
Air traffic control in Shannon told the worried pilot that there were no other aircraft in the area on their monitors.
G2 also took particular interest in a Dublin-based organisation, Spectrum, which was logging and investigating all such UFO sightings over Ireland.
Spectrum's work was also supported by a British peer, the Earl of Clancarty, who claimed that western governments were keeping secret files on UFOs.
