Between 1976 and 1979, the Spanish Canary Islands — a strategic Atlantic outpost of Spanish territory 100 kilometres off the African coast — experienced one of the most intense regional UFO flaps in Iberian history, with more than 130 formal witness statements gathered by the Spanish Air Force. The most celebrated incident occurred on the evening of June 22, 1976, when residents across multiple Canary Islands (Tenerife, Gran Canaria, La Gomera) observed a large spherical object, apparently transparent, that hovered offshore for several hours before ejecting what multiple witnesses described as 'two humanoid figures' visible through the sphere's translucent surface. The incident was observed by Spanish Navy patrol ships operating out of Las Palmas, by Naval Hospital doctors on Tenerife (including Dr. Francisco Padrón León, the case's principal medical witness), and by hundreds of civilian witnesses on multiple islands.
Dr. Padrón's formal written statement — lodged with the Spanish Guardia Civil on the night of the event — described two figures approximately three metres tall, wearing close-fitting red uniforms, visible through the transparent walls of the sphere. The Spanish Ministry of Defense opened a formal file, which was declassified in 1994 under Minister Julián García Vargas's extensive transparency initiative. The declassified file — publicly available through the Spanish Air Force archives — includes ship logs, radar data, photographs, witness statements, and an official note recording that the event 'could not be attributed to any known aircraft, weather phenomenon, or natural occurrence.'
The 1976 incident was the most significant of a cluster that included additional substantial reports on November 19, 1976 (off Fuerteventura) and March 5, 1979 (multiple-witness disc landing on La Palma). The Canarian cluster was investigated in depth by researchers José Juan Montejo, Joaquín Mateos Nogales, and Vicente-Juan Ballester Olmos, whose 1988 book 'Spanish Air Force UFO Files' catalogued the Canary Islands wave as the peak period of Spanish UFO activity. The 1976 case is the best-documented military-acknowledged entity-visible encounter in European history, on the basis of its medical-professional witness and the subsequent Ministry of Defense declassification.
