The most comprehensive Government files on UFO activity are opened to the public for the first time today and they disclose that even air traffic controllers and police officers have seen mysterious craft in the skies over Britain.
The sightings range from incredible tales of little green men visiting the Wirral to corroborated accounts from policemen and pilots of Unidentified Flying Objects hovering above towns and cities.

All are recorded on official forms, held by air bases and police stations, and compiled by the Ministry of Defence between 1978 and 2002.

Disclosed for the first time is a report from three experienced air traffic controllers who attempted to "talk in" a UFO which landed on the runway before them. The incident occurred on April 19, 1984, at an East Anglian airfield which was operating two runways called 22 and 27
