Scott C Waring, editor of ufosightingsdaily.com, described the object as a “croissant-shaped UFO” in a post on his website, which went onto suggest Malta was a mecca for aliens due to it being surrounded by ocean.
Mr Waring claimed Malta was an ideal location for “spotting alien objects as the tiny island off the coast of North Africa is surrounded by sea on all sides and is often frequented by sunny, clear skies.”
The case was originally reported to the US-based Mutual UFO Network (MUFON), which keeps a global database of alleged UFO and alien sightings.
The unnamed witness said in a report to MUFON it was snapped in Marsaskala.
They wrote: “It was a sunny day and I was taking photographs of the view and in three photographs the item appeared and I began noticing it for 15 minutes or so.
“Then it disappeared over the ocean.”
The image was reportedly taken in October last year, but has only just been reported to MUFON.
Mr Waring then took the leap to make his wild suggestion.
He wrote: “Most of the alien bases are below the ocean. I assume this since the ocean covers 75 percent of the Earth’s surface, that means 75 percent of the Earth’s surface is mostly unwatched because there are few humans out there except on a few ships and boats.
“Since aliens can build bases in space that are air tight, and below the surface of Venus, it’s just logical that aliens would utilise the untapped resource of our oceans to build bases.”
So it is much more theory than fact.
But, Mr Waring’s theory has been blasted out of the water… after it emerged the UFO in question was likely to be just a fluttering butterfly.
Scott Brando, who runs hoax-busting website ufoofinterest.org, examined the pictures and concluded it was just a Red Admiral, a butterfly commonly found in the UK and across Europe.
Mr Brando claims there is yet to be a picture or video taken of an alleged UFO that cannot be explained.
He tweeted: “A #UFO flying over #Malta? It’s most likely a butterfly like this.”
He then linked to a series of pictures of the Red Admiral that looked remarkably like the alleged UFO in the MUFON report.
