A Spanish contact case that ran from 1966 on more than a thousand pages of typed letters, purporting to come from visitors from a planet called Ummo and circulated first to Fernando Sesma in Madrid, then to researchers including Antonio Ribera and Rafael Farriols, whose Un Caso Perfecto (1969) is the standing dossier.

The Invisible College treats it as the fully developed specimen of a manufactured belief system. The doctrine was sophisticated enough to recruit government officials and French space scientists; it was self-inoculating, forbidding proselytising and warning its readers against adopting its own ideas; and it came with physical props, photographs, landing marks and nickel capsules holding strips of polyvinyl fluoride identified as duPont’s restricted TEDLAR, not obtainable on the Spanish market. The correspondents could never be traced, one witness pseudonym translates as Anthony Brown, and Jacques Vallee notes drily that a military technical school and airfield sit at the focus of the three sightings that carry all of UMMO’s physical evidence.

In 1993 José Luis Jordán Peña claimed authorship, saying he had built the myth to expose credulity; later statements complicated the account by naming collaborators and a foreign sociological experiment, and sole authorship is not universally accepted. Either reading serves the Control System Hypothesis, since the point Vallée draws from the affair is that human belief can be manipulated by physical and symbolic means working together.
