Expediente Número: 891205 — Avistamiento de Fenómenos Extraños (EVA-10 Noya)

This document details the investigation of an Unidentified Aerial Phenomenon (UAP) reported on December 5, 1989, at the EVA-10 Noya facility in Coruña, Spain. The incident began when an Antigaming Operator (A.J.O.) at the EVA-10 facility reported an unidentified object. At 18:48Z, the Air Surveillance/Radar Input Countermeasure Officer (AS/RICMO) confirmed the presence of an object between Santiago de Compostela and La Coruña. Reports from the Guardia Civil in Castro described the object as lenticular in shape, moving at low speed, and exhibiting bright, changing lights. Radar tracking on the RAPPI and UPA-35 systems identified a 'blitz' (echo) at an altitude of 57,000 feet, which later varied up to 75,000 feet. Attempts to obtain visual confirmation from civil aircraft were unsuccessful. At 20:00Z, emergency radio frequencies 121.5 and 243.0 experienced significant interference and confusion between Santiago, Madrid ACC, and NECORA. Later, at 20:40Z, a radiogoniometer localized the azimuth of the alarm, and three objects were detected at flight levels 290, 320, and 420. The radar tracking concluded at 21:02Z, though the echo remained on the RHI screen until 08:30Z the following day. The file was eventually declassified in September 1996, with the intelligence officer concluding that there was no reason to maintain its classified status.
