The UK Defense Department has declassified some top-secret files. One file shows that a boy scout was trailed by an unidentified flying object during the Second World War.
Several pilots in the area found the strange flying object from different positions. It seemed it followed the scout all the way home.
Then Prime Minister Winston Churchill ordered the reports about the unidentified flying objects to be kept secret in case they caused public panic at a time when the country was under threat of invasion by Germany.
In the past few years, the UK has declassified thousands of files referring to unidentified flying objects.
