A secret dossier that details one of Britain's most famous UFO sightings is to be kept secret for another 50 years.
It apparently contains incredible colour photos taken in 1990 that allegedly show a 100ft craft hovering over Calvine in the Scottish Highlands.
Two hikers were walking in the area when suddenly they say they saw a diamond shaped aircraft over the landscape before speeding off into the distance.
The two hikers took pictures of the craft and immediately contacted journalists from the Scottish Daily Record Newspaper.
After viewing their photos, the journalists chose to share both pictures and negatives with the Ministry of Defence.
A 30-year rule meant the file was meant to be declassified in January next year, but the Ministry of Defence has now blocked its release for another 50 years, until 2072.
UFO investigator Nick Pope helped colourise the famous image, and hit out at the MOD's decision to delay the dossier even further.
Another UFO hunter told The Sun : “This is all so frustrating. The Calvine Incident is one of the most intriguing of all the UFO mysteries from that period.
“Under the 30-year rule, the file should have been released on January 1 2021, but if the ministry get their way it won’t be released until January 1 2072 — an 82-year closure.
“By the time the world gets to see the file, the two witnesses will be dead. It is crazy. What are the authorities trying to hide?”
Elsewhere, the castle that will house I'm A Celebrity Get Me Out of Here! 2020 is a UFO hotspot, according to reports.
Gwrych Castle in Abergele, Wales is miles up the coast from Puffin Island, where well-known UFO hunter Russ Kellett believes a spaceship was found in the 1970s.
Mr Kellett believes the spaceship and alien visitors were covered up to avoid panic.
A source told the Daily Star: "The celebs will be braced for horrible trials and wet weather.
"But they could get something far more terrifying – an alien invasion."
Locals of the area have previously claimed that the castle itself is haunted by the potential for an alien sighting will add a whole other dimension to procedings.
"If there are any extra-terrestrial visitors, it will certainly make for good telly," noted the source.
In 1988, a trio of joggers believe they sighted a flying saucer above the village of Dwygyfylchi in North Wales.
This was followed by three separate sightings of what appeared to be an alien spacecraft above Abergele, according to a retired police officer in 1998.
