The Rendlesham Forest incident

In December 1980, a series of sightings of unexplained lights near Rendlesham Forest in Suffolk, England, sparked claims of UFO landings. The events took place just outside RAF Woodbridge, then used by the United States Air Force. Among the USAF personnel who reported seeing what he called a UFO was the deputy base commander, Lieutenant Colonel Charles I. Halt. This is the most famous alleged UFO event in the United Kingdom and is sometimes referred to as "Britain's Roswell," drawing comparisons to the Roswell incident in the United States. The UK Ministry of Defence concluded that the event posed no threat to national security and never investigated it as a security matter. Skeptics attribute the sightings to a series of nocturnal lights misinterpreted as a fireball, the Orfordness Lighthouse, and bright stars.

The first sighting occurred around 03:00 on 26 December 1980 (noted as 27 December in Halt's memo to the Ministry of Defence). A security patrol near the east gate of RAF Woodbridge observed lights descending into the forest, which astronomers later linked to a natural fireball over southern England at that time. Servicemen initially thought it was a downed aircraft. According to Halt's memo, upon entering the forest, they saw a metallic, glowing object with colored lights. As they approached, it seemed to move through the trees, and animals on a nearby farm became agitated. Sergeant Jim Penniston later claimed to have encountered a "craft of unknown origin" and touched it, finding it very warm, though this was not mentioned publicly at the time and lacks corroboration. Shortly after 04:00, local police were called but reported seeing only the Orford Ness lighthouse, miles away on the coast. After daybreak on 26 December, servicemen returned to a small clearing near the forest's eastern edge and found three small impressions on the ground, along with burn marks and broken branches. Police were called again at 10:30 and thought the impressions could have been made by an animal. Georgina Bruni's book *You Can't Tell the People* includes a photograph of the supposed landing site taken the morning after.

On 28 December (reported as 29 December by Halt), Halt and several servicemen visited the site and took radiation readings with an AN/PDR-27 survey meter. They recorded 0.07 milliroentgens per hour in the triangle of depressions, while other areas showed 0.03 to 0.04 milliroentgens per hour, near background levels. A similar small burst was detected over half a mile away. Halt recorded the events on a micro-cassette. During this investigation, a flashing red light was seen across a field to the east, near a farmhouse, similar to the first night's sighting. The Orford Ness lighthouse is visible further east along the same line of sight. Later, Halt's memo describes three star-like lights in the sky—two to the north and one to the south, about 10 degrees above the horizon. The brightest hovered for two to three hours and occasionally beamed down light. Astronomers explain these as bright stars.

Rendlesham Forest, owned by the Forestry Commission, covers about 5.8 square miles of coniferous plantations, heathland, and wetlands in Suffolk, roughly 8 miles east of Ipswich. The incident occurred near two former military bases: RAF Bentwaters to the north and RAF Woodbridge, which extends into the forest from the west. Both were under USAF command at the time, led by wing commander Colonel Gordon E. Williams, with base commander Colonel Ted Conrad and his deputy Lieutenant Colonel Charles I. Halt. The main events, including the supposed landings, took place in the forest starting about 0.3 miles east of RAF Woodbridge's East Gate, where security guards first saw lights descending. The forest extends about a mile east to a farmer's field at Capel Green, where additional events allegedly occurred. Orfordness Lighthouse, identified by skeptics as the flashing light seen by airmen, lies about 5 miles further east along the same line of sight and was one of the UK's brightest lighthouses at the time.

One proposed theory is that the incident was a hoax. The BBC reported that former U.S. security policeman Kevin Conde claimed responsibility for creating strange lights by driving a police vehicle with modified lights, but no evidence places this prank on the nights in question. Other explanations include a downed Soviet spy satellite, though no evidence supports this. The most widely accepted skeptical view remains the misinterpretation of natural and man-made lights.
