Newly released UFO files from Britain's National Archives

Britian’s National Archives has release 25 files related to UFOs ranging from 1965 to 2008.
Included in the released info are various analyses regarding alien visitation.
Briefing for House of Lords UFO debateIn a briefing prepared for MoD prior to the House of Lords UFO Debate in 1979 a UFO (DI55) Intelligence Officer questions why in such a vast universe aliens would want to visit “an insignificant planet (the Earth) of an uninteresting star (the sun)”. He says such a visit “would probably not occur more than once in a thousand years or so, even if one assumes that every intelligent community made say 10 launches a year.” He questions why, if UFOs were piloted by aliens, no “intensive radio listening searches carried out by reputable scientific organisations, particularly in the US, have intercepted some of the transmissions between spacecraft or between spacecraft and their base”. He concludes “claims of thousands of visits in the last decade or so are far too large to be credible.” (p157)
If you build it, they will come
Alien TourismA 1995 briefing by a UFO desk officer at DI55 on the need for a full study of UFO data as national security implications have never been properly assessed. Under the heading „possibilities‟ the author lists mass hallucinations, hoaxes, US Black Project aircraft, Russian or Chinese aircraft or Extra-Terrestrial visitors. He says there is no hard evidence for alien craft but says “if the sightings are not of this earth then their purpose needs to be established as a matter of priority. There has been no apparently hostile intent and other possibilities are: a) military reconnaissance b) scientific c) tourism”(p38-43).
Harnessing UFO technologyA UFO Intelligence officer flags up need to capture UFO technology for UK use: “…if the reports are taken at face value then devices exist that do not use conventional reaction propulsion systems; they have a very wide range of speeds and are stealthy. I suggest we could use this technology, if it exists.”(p38-43)
US interest in UFOsDEFE 24/1985/1 (p239-40) contains a response by MoD to a US Air Force request for information on British UFO policy in 1965. MoD says “our policy is to play down the subject and to avoid attaching undue attention to it”, as a result there had never been any political pressure for an official study. In 1995, the UFO Desk asked RAF Air Attache in Washington to ascertain the US Department of Defense‟s „line on UFOs.‟ In file DEFE 24/1985/1 (p81-82) the response says “after posing the questions to a variety of staff [in HQ US Space Command] and receiving blank stares in return” he was referred to the Department of Defense‟s website which said the US had no interest in UFO reports, a policy which was “consistent with our own, but they discourage approaches from the public rather more politely than we do.”
UFO sightings and reports‘Welsh Triangle’ and silver-suited spacemen (DEFE 24/2043/1 p31-48)A spate of UFO and alien sightings in West Wales during 1977 led to tabloid headlines linking the region with the infamous Bermuda Triangle. The local MP, Nicholas Edwards, said he was “inundated” with reports from constituents and asked MoD to investigate. He received a letter from the proprietor a local hotel who claimed she saw a dome-shaped object land “like the moon falling down” behind the hotel. Two tall silver-suited “faceless humanoids” emerged and began “making measurements”. She told her MP she was left in a state of shock. MoD asked the RAF police to make “discreet enquiries” in the area and sent an officer from RAF Brawdy to interview the woman. He suspected a practical joker was at work in the area and noted that a silver protective suit used in nearby oil refineries had been on display in a shop window at Haverford west shortly before the ‘spacemen’ were seen.
‘Men in Black’ visitation(DEFE24/2089/1 p471)A member of the public from Spalding, Lincolnshire who had reported a UFO encounter to police, later went on to receive a late night visit from three tall men dressed in black suits who “seemed to move silently”, according to a friend who witnessed the visit whilst hiding in the downstairs toilet. The men apparently broke in through the back door, before entering the bedroom of the UFO witness and having a conversation, the content of which was not overheard. The “petrified” friend locked themselves in the toilet until „men in black‟ left in a black Jaguar soon afterwards. When asked afterwards, the UFO witness did not recall seeing any „men in black‟ or encountering a UFO in the first place.
Alien Abduction in Scotland(DEFE 31/189/1 p360-61)A report submitted to MoD in August 1992 by two men described a UFO seen over the A70 which “dropped a curtain of light across the road”. The men later underwent regression hypnosis and an alien abduction story emerged. This story is the basis of a feature film to be released later this year.
Chinese lantern UFOs 2005-7A craze for releasing sky lanterns led to a spate of UFOs reports to MoD from 2005.DEFE 24/2083/1 (p180-190 and p149-50) includes four separate reports of “golden orbs” seen by people near Loughton tube station in Essex and reported to police in September 2005. In DEFE 24/2088/1 (p155) a similar sighting from Brighton in August 2007 led a woman to call the MoD’s UFO hotline panicking [and] saying we had to ring her back (She left three messages saying this). She was petrified and so were her friends. She had never seen anything like this before”. A caller from Houghton-le-Spring, Co Durham, saw similar lights but did not think they were UFOs as he didn’t believe aliens would want to visit Houghton (p146-7).
UFO sighted by Police(DEFE 31/194/1 p11)A mounted police officer reported a sighting of a square/diamond shaped object moving across the sky and changing shape” whilst on duty at Chelsea FC ground in 1999.
