A cover-up by Sir Winston Churchill is among hundreds of close encounters described in previously top-secret files released by the Ministry of Defence (MoD).
More than 5,000 pages of material spanning from 1995 to 2003 holds hundreds of other-worldly experiences with unidentified flying objects (UFOs) and apparent aliens across Britain.
Sir Winston Churchill was accused of covering up a close encounter between an RAF aircraft and a UFO during the Second World War. Details emerged after one his former bodyguards wrote to the MoD in 1999 about comments he had overheard Britain's war leader making.
The former prime minister allegedly ordered that the unexplained incident over the east coast of England should be kept secret for at least 50 years because it would provoke "mass panic".
This is just one of hundreds of the bizarre reports received by the police, military and Government, suggesting that the truth might be out there after all.
This sixth instalment released under a three-year project between the MoD and The National Archives consists of 18 files of UFO sightings letters and Parliamentary Questions.
