AVISTAMIENTO DE FENOMENOS EXTRAÑOS (EXPEDIENTES OVNI) - EXPEDIENTE NÚMERO: 681211B

This document, designated as file 681211B, details a UFO sighting reported in El Garrobo, Sevilla, on December 11, 1968. The primary witness, a chemist, reported observing an intense, color-changing light while driving toward a farmhouse at approximately 21:00 hours. The object was estimated to be one kilometer away, flying at an altitude of 50 to 100 meters, moving in a NE-SW direction while following the terrain's contours. The witness noted the object made no noise and moved slightly faster than his car. Upon reaching the farmhouse, the witness informed the local mayor, who subsequently investigated the area with neighbors. These additional witnesses observed the phenomenon at 23:00 hours, approximately three kilometers away, moving in a N-S direction. The report, authored by the Lieutenant General of the Second Air Region, notes that the witness's claim that the object was not an aircraft due to the lack of noise should be treated with caution, as the witness was inside a moving vehicle. The military intelligence assessment concluded that there was insufficient data to determine the origin of the phenomenon and explicitly ruled out ball lightning due to the duration of the event. The file was subsequently declassified on April 21, 1993, with the note that no further investigation was conducted and no classified status was warranted.
