UFO sightings in the United Kingdom - Wikipedia
Across centuries a long-running UK catalog of notable alleged UFO sightings shows many cases later explained as misidentifications or natural phenomena, with London, Manchester, and Birmingham as the busiest hotspots; reports range from medieval glowing lights described as dragons to early-20th-century scareships, mid-20th-century saucer-like sightings and radar events such as Tangmere, Bentwaters, the 1952 North Sea activity and Channel–aircraft encounters (along with weather balloons and Venus), a 1960s wave including Warminster and cross-shaped sightings in Sussex and Devon, the 1980 Rendlesham Forest case and other 1980s reports like Dechmont Law and Broad Haven, the 1990 Calvine photographs, and later Bonnybridge activity, with government responses and freedom-of-information disclosures tending to attribute many sightings to mundane causes even as some remain unexplained, and researchers use the record to illustrate the tension between extraordinary claims and ordinary explanations.
