AVISTAMIENTO DE FENOMENOS EXTRAÑOS (EXPEDIENTES OVNI) - EXPEDIENTE NÚMERO: 6811 / 12RV

This document is a declassified file (6811/12RV) from the Spanish Air Force (Ejército del Aire) regarding a series of unidentified aerial phenomena reported in the vicinity of Puente Almuhey, Leon, between November 24 and December 10, 1968. The file contains a summary of sightings, witness declarations, and official correspondence from the Military Aerodrome of Leon and the Air Region Command. Witnesses reported various objects, described as having shapes ranging from circles and spheres to ovoids and lanterns, with colors including red, yellow, and white. The objects were generally described as moving slowly or remaining stationary at altitudes estimated between 300 and 500 meters. Some witnesses reported the objects changing shape or decomposing and regenerating. The investigation, conducted by Air Force captains, involved interviewing witnesses and consulting with the aerodrome meteorologist, who could not identify the phenomena as known atmospheric events. The official conclusion stated that due to the scarcity of data and the vague nature of the witness reports, it was impossible to determine the nature of the objects with any reliability, though it was suggested that they might have been the Moon or the planet Venus under specific visibility conditions. The file was declassified on March 26, 1993, with the recommendation that it no longer be maintained as classified.
