AVISTAMIENTO DE FENOMENOS EXTRAÑOS (EXPEDIENTES OVNI) - EXPEDIENTE NÚMERO: 690926

This document file, numbered 690926, details the investigation into the sighting of unidentified luminous objects over the province of Gerona, Spain, on September 26, 1969. The report, compiled by the Chief of the Gerona-Costa Brava Airport, documents testimonies from airport staff, including the Service Officer, the Meteorological Observer, the Driver, and the Aeronautical Technical Engineer. Witnesses reported observing a luminous object at approximately 17:30 Z, estimated to be at an altitude of 25,000 to 30,000 feet. A second object with similar characteristics was observed at 17:50 Z. The objects were described as having intense brightness. The investigation, which included internal reports and correspondence between the Air Force (Ejército del Aire) and the 3rd Air Region, concluded that the phenomena were likely weather balloons launched by French observatories. This conclusion was based on the similarity of the objects to previous sightings that airport personnel were familiar with. The file includes various teletypes and official letters documenting the reporting process and the final assessment that the matter did not require further investigation or classified status. The file was subsequently declassified on September 21, 1993.
