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.
