The aliens of the Serpo project. Science fiction?

A piece of news to grab is that reported by some American journalists who transcribed the information received from an official of the American DIA, the Defense Intelligence Agency, about the supervision of the “Serpo” program managed by the famous Majestic-12 group.

But what did this program consist of? A super secret affair that came out in 2005 but took place in 1965 when 12 American military experts, 10 men and 2 women started an exchange with a group of aliens contacted through the only survivor after the Roswell crash and coming from the Zeta reticuli star system. The exchange involved the transfer of the 12 to their planet named Serpo while one of them remained here on earth, to note that the name of the s.s is the same from which the aliens came who kidnapped the spouses Barney and Betty Hill in 1961.

The exchange allowed the 12 military to spend 10 years of their life on this planet 39 light-years away from the earth, the journey lasted about 9 months for the record. Of the 12 parties, however, only 7 men and a woman returned from the planet Serpo, 2 decided to stay there, the others died from various causes.

Those who survived after returning spent nearly a year in a secret facility under the supervision of doctors and scientists but soon began to die one by one.
By the end of 2002 they had all died.
Scientists of the time thought of a certainly lethal dose of radiation present on Serpo.

The planet showed to say of the military environmental conditions especially at atmospheric level very different from the earth and the presence of two suns was the main cause of death from exposure to radiation too high for humans.
According to another anonymous source always to be taken with pliers, the American Russians had already colonized the planet Mars in the early years of 1964.

Will it be true? What do you think?
