In the last declassification of British troops about this subject, the Department of Defense has revealed reports of UFOs over the most famous British tourist sites. But this last dose does not contain any solid evidence of extraterrestrial life.

This batch contains 4 300 pages relating to the period starting at the end of the year 2007 until the UFO Investigation Unit dissolution unit at the end of the year 2009.

One set dated January 2009 recalls the random observation of a strange object hovering over Stonehenge: "At that time I did not see anything in the sky because I focused on those stones," the witness wrote in an archival e-mail. "But when I uploaded the pictures to my computer, I discovered disc-shaped shapes in the background. 'I'm sure you get something like this every day! But I found great interest in my UFOs, so I need to share them! "

Another witness reported sight "A device that had green, red and white lights" above the parliament building in February 2008.

The Armed Forces have rejected both reports as not posing any security risk to the UK, until it remains unclear whether the observations were authentic, let alone whether the UFO in question came in peace.

Dear Sir, dear Madam,

I am a 9-year-old student at a school in Ridings and I am involved in a controversial project on whether or not there are aliens. I would be grateful if you could provide me with any information about extraterrestrial life, because I also need to include some information from credible sources. I would also like to know if the government or the DoD believe that the aliens exist and have already had some contact with our planet.

Thank you for your time and I look forward to seeing you soon.

With respect to your ...

The Ministry of Defense has decided to end the 'X-Files' program after the infestation with digital cameras and mobile phones contributed to a rocketing increase in the number of UFO sightings.

In the first 11 months of 2009, before the hotline was cut off, the ministry collected 643 reports. For comparison, between 2000 and 2007, the MoD received about 150 reports per year. The MoD speculated that the sudden surge was due to the great popularity of Chinese lanterns at the time.

The ministry found that its resources were overburdened by a flood "To defend the worthless" complaints from the investigation and decided not to continue the program.

"During more than 50 years, none of the UFO reports have revealed any evidence of a potential threat to the United Kingdom," said defense officials in 2009. It would be "Inappropriate use of resources to defend," if we continue to spend time and money on this activity, they added.
