The first mention of a 'Project Serpo' was in a UFO email list maintained by enthusiast Victor Martinez. Various versions of the conspiracy theory circulated and were later detailed on a website. According to the most common version of the story, an alien survived a crash near Roswell in the later 1940s (see Roswell UFO incident). This alien was detained but treated well by American military forces, contacted its home planet and eventually repatriated. The story continues by claiming that this led to the establishment of some sort of relationship between the American government and the people of its home world, said to be a planet of the binary star system Zeta Reticuli.
