Expediente Número 01-MACEN-93: Avistamiento de Fenómenos Extraños en EVA-10 Noya

This document is a comprehensive file (Expediente 01-MACEN-93) regarding an Unidentified Aerial Phenomenon (UAP) sighting that occurred on November 23, 1993, at the EVA-10 Noya surveillance station in La Coruña, Spain. The report includes the initial incident report, official correspondence between military commands, and detailed questionnaires completed by five witnesses, including the station commander and other military personnel. The witnesses, who were at the entrance control of the EVA-10 facility, reported observing a bright green luminous object with a white-yellowish trail moving at high speed in a rectilinear, horizontal trajectory from Southeast to Northwest. The duration of the sighting was estimated at approximately 3 to 4 seconds. The witnesses described the object as having a bright green nucleus, similar to a marine flare or a firework, and noted that it left a trail of sparks. No sound was reported, and no physical traces or physiological effects were observed. Military radar logs for the period between 07:00 and 09:00 local time showed no anomalous echoes, and there was no military air activity in the area at the time. The investigation, conducted by the Mando Aéreo del Centro (MACEN), concluded that the phenomenon was likely a natural event, specifically a meteor. The report notes that the low angle of observation and the chemical composition of meteorites (specifically iron-sulfur compounds) could account for the bright green light described by the witnesses. The final assessment by the General Chief of the Mando Aéreo del Centro stated that the speed and rectilinear trajectory did not suggest a vehicle of unknown origin, and therefore recommended that the file be classified as 'unclassified' information.
