"Aliens from outer space have been visiting Britain for years and UFO sightings doubled after the film Close Encounters was released in 1977, according to secret files collating reports by members of the public.

The alien craft come in all shapes, sizes and colors but their occupants are uniformly green, the Ministry of Defence files show.

The archives (at www.nationalarchives.gov.uk/ufos) are the first batch of a four-year release programme of all the ministry's UFO files from 1978 to the present day."
