Smivs writes "Britain's Ministry of Defence has just released files regarding investigations into UFO sightings between 1978 to 1987. Over the next three or four years, 160 files will be handed over to the National Archives. The first group of eight files, one of which is more than 450 pages long, is available today. The Guardian newspaper details many of the events in question, some interesting and many just bizarre. A similar release of UFO files by France's national space agency last year attracted more than 220,000 users on its first day, causing it to crash. To avoid such problems, the National Archives is using an external hosting company which can add extra capacity as needed to handle the web traffic."
