UFO sighting in Alcorcon from 1978

Summary

In March 1978, a witness in Alcorcon (Madrid) captured a series of photographs showing luminous traces in the sky. The Spanish Air Force received these images and analyzed them decades later, in 1995, using digital processing techniques. The results revealed no solid objects or unexplained phenomena. The lights appeared to be aircraft trails or photographic manipulations. Although the file was declassified, the story remains an example of how sightings were handled in that era.
