ANALISIS DE UN "CLASICO": MORON DE LA FRONTERA 11 de MAYO de 1970

This document is a detailed retrospective analysis written in January 1984 by J.A. Fernández Peris regarding a famous UFO sighting incident that occurred on the night of May 10-11, 1970, in Morón de la Frontera, Spain. The incident took place on the 'Rancho del Maestro Oliva' farm, owned by the Gordillo family. Following a severe thunderstorm, Manuel Gordillo discovered strange circular traces and damaged sunflower crops on his land. The document meticulously reviews the various interpretations of these traces, contrasting the official findings of the Provincial Agronomic Headquarters of Seville with the theories proposed by contemporary ufologists and the media. The official investigation, conducted by agricultural experts, ruled out known pests or diseases, noting that the plants appeared 'calcined' and damaged at the base, suggesting an external impact. However, the report emphasizes that the official investigation could not definitively identify the cause, leaving it as an unexplained 'impact.' Conversely, local ufologists, including Luis Camacho Moreno, Manuel Osuna, and Felipe Laffitte, interpreted the traces as evidence of an extraterrestrial landing, citing the geometric precision of the holes and the alleged metallic residue. The author of this report critically examines these claims, noting the lack of rigorous measurement and the tendency of the ufological community to interpret ambiguous data as proof of alien activity. The document also provides extensive meteorological data confirming a strong electrical storm in the area at the time, which the author argues is the most plausible explanation for the phenomena, despite the lack of direct evidence of a lightning strike. The report concludes by highlighting the sociological impact of the event, noting how the media and ufologists amplified the incident, often ignoring the more mundane reality of the situation. It serves as a case study on the methodology of UFO investigations in Spain during the 1970s and the psychological mechanisms behind the creation of such 'myths.'
