Fear of Earth invasion as the number of mysterious ‘alien crafts’ sighting doubles

USA: The number of UFO sightings doubled in June, according to an international group of sky gazers.

The Mutual UFO Network (MUFON), which collates UFO evidence from around the world, recorded sightings of 1,179 mysterious unexplained crafts last month - up from just over 600 in the same period last year.

So does this spike in activity mean aliens are preparing to invade Earth and turn us into a slave species?

Happily, it doesn't appear so.

Roger Marsh, MUFON director of communications, doesn't seem too worried.

He offered a distinctly terrestrial explanation for the UFO sightings.

“We feel [it] was directly related to the final two episodes of Season 2 of 'Hangar 1: The UFO Files,'" he told the alternative news site Open Minds.

This show aired on the History Channel in America and featured extensive contributions from MUFON.

"A very high percentage of the June UFO report surge were historical cases," Marsh added.

"People were watching our show and decided they finally discovered a place where they could report their encounter.

"Some of these are very, very interesting and compelling cases currently under investigation.”

He also had another explanation for the UFO explosion which took place last month.

"Many more people are celebrating outside during the evening hours and are looking up," he said.

Reading between the lines a bit, this might mean that revellers are flat on their back after a few too many hours in the pub.

And when you're in a state like that, who knows what mysterious flying objects you'll see?
