This report documents a series of UAP sightings in Spain in May 1968, which were officially attributed to French stratospheric balloon launches. It highlights the military's response, including failed interception attempts and the loss of passenger-recorded film evidence.
This document is a declassified intelligence report from the Spanish Air Force (Ejército del Aire) regarding a series of unidentified aerial phenomena (UAP) sightings that occurred over Madrid and Barcelona on May 15, 1968. The report details multiple observations, including reports from the Junta de Energía Nuclear de la Moncloa, commercial airline pilots, and military radar contacts from EVA 4. The objects were described as metallic, having a 'three-body' or 'tetrahedral' appearance, and were observed at varying altitudes. The Spanish Air Force attempted to intercept the objects using military aircraft, including a 'scramble' of F-100 USAF jets, but identification was hindered by altitude and coordination issues. A passenger on an Iberia DC-9 flight filmed one of the objects, but the film was subsequently lost within the administrative channels of the Air Staff. The final assessment by the Intelligence Section of the Air Operational Command concludes that the sightings were consistent with a wave of stratospheric balloon launches conducted by the French CNES (Centre National d'Etudes Spatiales) during that period. The report notes that the metallic appearance and lack of mobility reported by witnesses align with the characteristics of these large, regular-tetrahedron-shaped balloons.
Tales parámetros, unidos a la coincidencia en tiempo con los lanzamientos indicados, avalan la hipótesis de que, en ambos casos, se trata de GLOBOS ESTRATOSFERICOS.
