On July 16, 1965, a massive alien spacecraft from the Zeta Reticuli star system landed at the Nevada test site north of Las Vegas. Following a plan set in motion by President Kennedy in 1962, the alien visitors known as the Ebens welcomed 12 astronaut-trained military personnel aboard their craft for the 10-month journey to their home planet, Serpo, 39 light-years away. In November 2005, former and current members of the Defence Intelligence Agency - directed by Kennedy to organise the Serpo exchange programme - came forward to reveal the operation, including details from the 3,000-page debriefing of the 7 members of the Serpo team who returned after 13 years on the planet. Working with the DIA originators of the Serpo project and the diary kept by the expedition's commanding officer, Len Kasten chronicles the complete journey of these cosmic pioneers, including their remarkable stories of life on an alien planet, super-luminal space travel and advanced knowledge of alien technologies. Exposing the truth of human-alien interaction and interplanetary travel, Kasten reveals not only that the Ebens have returned to Earth eight times, but, also, that the US government continues to have an ongoing relationship with them - a relationship with the potential to advance the human race into the future. He reveals how the Ebens presented the U.S. with "The Yellow Book"—a complete history of the universe recorded holographically, allowing the reader to view actual scenes from pre-history to the present. He explains how the Ebens helped us reverse-engineer their anti-gravity spacecraft and develop technology to solve our planet-wide energy problems — knowledge still classified. · Based on the debriefing of the Serpo team and the diary of the expedition's commander · Explains how the aliens helped us reverse-engineer their antigravity spacecraft and develop technology to solve our planet-wide energy problems · Reveals how our government has an ongoing relationship with the Serpo aliens
