It was 1965 when a series of unknown objects fell out of the sky near Badajoz and Sevilla, with the United States asked for the incident to be classified top secret and did not inform NATO of what had happened, but General Francisco Franco was told, and an investigator who specialises in UFOs from Valencia has been revealed as the only person with all the information.

Vicente Juan Ballester Olmos is the only person who has had full access to the three hundred page document that spells out the details of the fourteen strange items recovered, in what many see as the most extensive report ever published into UFOs.

However another theory expresses the belief that what really fell on Spain that December day in 1965 was pieces that fell off a Russian spacecraft launched from the Baikonur.
