Witnesses report the first of several sightings of unexplained lights near RAF Woodbridge, in Rendlesham Forest, Suffolk, England, United Kingdom, an incident called "Britain's Roswell".

The Rendlesham Forest incident was a series of reported sightings of unexplained lights near Rendlesham Forest in Suffolk, England, in December 1980, which became linked with UFO landings. The events occurred just outside RAF Woodbridge, which was used at the time by the United States Air Force (USAF). USAF personnel, including deputy base commander Lieutenant Colonel Charles I. Halt, claimed to see things they described as a UFO.

Royal Air Force Woodbridge, or more simply RAF Woodbridge, is a former Royal Air Force station located east of Woodbridge and around 7 miles north-east of Ipswich, in the county of Suffolk, England.

Rendlesham Forest is a 1,500-hectare (3,700-acre) mixed woodland in Suffolk owned by Forestry England with recreation facilities for walkers, cyclists and campers.

Suffolk is a ceremonial county in the East of England, with some of it being part of the East Anglia section. It is bordered by Norfolk to the north, the North Sea to the east, Essex to the south, and Cambridgeshire to the west. Ipswich is the largest settlement and the county town.

The Roswell Incident started in 1947 with the recovery of debris near Roswell, New Mexico. It later became the basis for conspiracy theories alleging that the United States military recovered a crashed extraterrestrial spacecraft. The debris was a military balloon operated from the nearby Alamogordo Army Air Field and part of the top secret Project Mogul, a program intended to detect Soviet nuclear tests. After metallic and rubber debris was recovered by Roswell Army Air Field personnel, the United States Army announced their possession of a "flying disc". This announcement made international headlines, but was retracted within a day. To obscure the purpose and source of the debris, the army reported that it was a conventional weather balloon.
