REPORTS of a possible visit by an alien life-form to the North-East have been revealed in Britain's version of the X-Files.

Classified documents published to comply with the Freedom of Information laws contain observations of unidentified flying objects reported by RAF personnel, airline pilots and senior police officers.

One of the most credible sightings revealed in the papers, previously held by the Ministry of Defence's UFO department SF4, is one made at RAF Boulmer, in Northumberland, in July 1977.

The documents include a sighting by Flight Lieutenant A M Wood, who reported "bright objects hanging over the sea".

Two NCOs also saw what the RAF officer described as "luminous, round and four to five times larger than a Whirlwind helicopter".

The UFOs were said to be three miles out to sea at a height of about 5,000ft.

The report adds: "The objects separated. Then one went west of the other, as it manoeuvred it changed shape to become body-shaped with projections like arms and legs."

Men who were at the picket post at the RAF station observed the strange objects for an hour and 40 minutes,

Flt Lt Wood is described in the report as "reliable and sober", while a radar station also detected the objects in the position the men had observed them.
