The Royal Air Force (RAF) ran a UFO unit for 50 years that took in public sighting reports but it was shut down in 2009 after it was determined none of the reports offered evidence of a real threat. The records from the unit were then given to the British National Archives where they were classified.
A spokesman for the RAF said that "it had been assessed that it would be better to publish these records, rather than continue sending documents to the National Archives, and so they are looking to put them on to a dedicated gov.uk web page."
A clearance process for the documents is currently underway before publication, which is expected to take place "sometime within the first quarter of 2020," according to the Telegraph.
"Given the massive public interest in this subject, I'm pleased that these files will be released and made available online," said Nick Pope, who used to investigate UFO sightings for the country's Ministry of Defense (MoD).
In June 2013, the MoD previously reported it was releasing the final UFO files in the UK's possession. However, we now know that's not true thanks to a Freedom of Information Request by PA News.
In response to the FOI, the RAF described the files it held as "comprising entirely of correspondence with members of the public."
"The MoD has no opinion on the existence or otherwise of extraterrestrial life and does not investigate UFO reports."
