Hopefully the British will one day release the unedited files of the Rendlesham Forest UFO incident, but it most defiantly a real sighting, otherwise the British would have already released those documents long ago. Governments usually release the fluff, the soft core stuff to satisfy the public, but hide the serous hard core documents due to national security.

News states: 
Colonel Charles Halt, one of the key US military witnesses during the perplexing incident, claims important details were missing when the MoD released formerly classified files on the case which dates back to 1980.

The UFO sighting happened when three US officers based at RAF Bentwaters claimed a "triangular shaped craft" landed in neighbouring woods in the early hours of December 26 1980.

Retired Col Halt, 76, who was base deputy commander at the time, claimed three officers who first saw the lights, and then a UFO "on the floor", could not account for a 40 minute period while searching in the woods when their communication systems went "off air".

Halt said: "When the documents were released, the time frame when I was involved in the incident is missing – it’s gone missing."

Col Halt spoke ahead of the publication of a new book which details the Rendlesham case from his perspective for the first time.

He also claimed the conclusions of MoD investigations into what happened had never seemed to be released.

He added: "In the last six years the British have released a ton of information, but has anybody ever seen what their conclusions were, or heard anything about Rendlesham officially?"

Col Halt became involved in the Rendlesham incident on the second night after the officers reported the missing time.

The three officers - John Burroughs, Bud Steffens, and James Penniston, later told of feeling "static" as they observed the object's flashing lights and hieroglyphic-like markings.
