AVISTAMIENTO DE FENOMENOS EXTRAÑOS (EXPEDIENTES OVNI) - EXPEDIENTE NÚMERO: 670910 / 11

This document file, numbered 670910/11, contains intelligence assessments and correspondence regarding Unidentified Aerial Phenomena (UAP) sightings over Spanish territory in September 1967. The file originates from the Spanish Air Force (Ejército del Aire) and was declassified in September 1997. The primary incidents involve reports from British charter flight crews who observed unidentified objects while flying over Spain on September 10 and 11, 1967. One report describes a cone-shaped object observed at 16,000 feet, 80 nautical miles northwest of Barcelona. A second report describes a similar sighting 65 nautical miles north of Reus. Additionally, the file documents a radar detection on September 12, 1967, where the Paracuellos Control Center reported an unidentified echo moving very slowly. An operator at the Torrejón AMIS facility visually confirmed a very bright point with almost zero displacement speed. The intelligence section of the Air Force Staff (EMA) analyzed these reports, noting that the objects' characteristics—specifically their luminosity and low speed—could not be easily explained as weather balloons or satellites. The intelligence officer recommended that the Spanish military establish a formal information and analysis center to study these phenomena and suggested initiating official or unofficial exchanges with international organizations dedicated to UFO research. The file concludes with a proposal to declassify the information, as it was determined that there were no aspects requiring the maintenance of classified status.
