Secret Journey to Planet Serpo: A True Story of Interplanetary Travel Audible Audiobook – Unabridged

4.5 4.5 out of 5 stars 1,534 ratings

Documents how 12 people, as part of a top-secret US government program, traveled to the planet Serpo and lived there for 13 years

  • 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

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 Defense Intelligence Agency - directed by Kennedy to organize the Serpo exchange program - came forward to reveal the operation, including details from the 3,000-page debriefing of the seven 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, superluminal space travel, and advanced knowledge of alien technologies. He reveals how the Ebens presented the US with "The Yellow Book" - a complete history of the universe recorded holographically, allowing the listener to view actual scenes from pre-history to the present. He explains how the Ebens helped us reverse-engineer their antigravity spacecraft and develop technology to solve our planet-wide energy problems - knowledge still classified.

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 our government continues to have an ongoing relationship with them - a relationship with the potential to advance the human race into the future.

It's a well put together book.
I just finished reading “Secret Journey to Planet Serpo” by Len Kasten. In a nutshell it describes what an Air Force Colonel kept in his diary. He was one of the 12 human military personnel who supposedly documented about his ten month experience traveling to the alien planet and the 13 years they were in the "Ebens" care. Remember the ten men and two women in red flight suits with sunglasses that were going with Roy Neary at the end in Close Encounters of the Third Kind?I have a lot of questions. Let’s say this was real and it happened. The fact that the “Ebens” had difficulty understanding our concept of time, and us with theirs, bothers me. They are able to travel through space in “space tunnels” (worm holes as we now call them) and bypass the law of speed of light, yet can’t be superior with numbers? Math is universal. Now don’t you guys start saying, “Well on Planet Serpo, their math is different.” No, it’s not. Please don’t blanket that kind of excuse for everything. Because of math, we understand time. We can understand that time is different in other celestial bodies. It’s even explained on page 194. Math is a universal constant. One is always going to be one, and two is always going to be two and it doesn’t matter where you are on Earth or on "Serpo."Another headache I got from this was nothing was mentioned about the planet’s gravity or it’s effect on the 12 humans. I would think that would be the first thing these humans would have experienced before stepping off the mother ship onto the Arizona-desert-looking environment.One nugget of info that I thought was cool was the fact that the aliens were curious as to what the Hell we were doing with the atom bomb. They did not have weapons of mass destruction like that.I’m going to guess there is an ounce of truth with this book with a gallon of “Eben” BS dumped on top of it.Now this unparalleled meeting and exchange took place in the 1960s during the space race with the Soviets. Americans traveling to another planet would have trumped the Russians hands down and would have given us bragging rights...Just like we did with the moon landings. This feat would not have been kept silenced. It would have been celebrated. Now some of you may say, "Well it was covered up because it was compartmentalized due to the Defense Intelligence Agency." That may be true and to help that argument, Bob Lazar said the biggest problem with his work in reverse engineering was because of department compartmentalization. None-the-less, Reagan KNEW and gave an address about the importance of protecting the Earth from a hostile alien race. He could have disclosed more then, but he didn't.My last thought on this extraordinary account, if true, the military should have sent smarter humans and seeds to grow a garden. The books makes the military look stupid and not capable for forecasting basic human requirements. By bringing seeds, they could have grown their own food on that planet when their rations were depleted. The book states the humans had a hard time enjoying and digesting Serpon food and had ran out of salt and pepper to make it tolerable. Then there was the protein issue. It is stated that the humans "killed a beast" and ate it. It supposedly tasted like bear. The animals described by this "anonymous" man are juvenile descriptions. "The strangest was the beast which looked like a large ox. the animal was timid and never seen to be hostile. Another animal looked like a mountain lion, but had long fur around the neck. This animal was curious, but was not considered hostile by the Ebens." I won't even touch on the giant snake that had human eyes.I come away from this reading....very angry. I would like to think the USAF was smarter than this in 1965 with what it was sending to this alien world. And we won't even talk about the radiation issue that allegedly was the cause of the humans (that returned to Earth) their eventual deaths. Do the "Ebens" even know about science and solar radiation or are they just winging it?At the end of the day, it is a fantastic read. And like watching a Michael Bay movie, you need to turn off your brain and just enjoy the story. I recommend it.

Some books take time to develop, but this book gets your attention from the start. It covers the Nazi UFO program and Antarctica, which to this day is basically a secret military base. Nobody really knows what the military and scientists are doing there. Then on to Roswell, and the secret space program. It really makes you wonder if disclosure has happened before our eyes, in the form of movies. Close Encounters of the Third Kind is mentioned in the book. Maybe the sequel to CETK should be made to cover the experiences of the astronauts on Serpo. It's a remarkable story but sadly the more you read, the more questions you will have. Many of those questions will go unanswered. The truth is out there, someone just needs to disclose it. The human race deserves to know the truth, and I believe we CAN handle it. Back to the book, it ends rather quickly. I think this is because detailed information about the planet and the return trip simply isn't available. The sheep dip process was mentioned, and likely a sad, lonely fate for those who made the journey. There will be skeptics, I get it. But i do believe there is something to this book, I just wish there was more of it to read!

When I was once a member of Open Minds Forum (now defunct), I was very intrique with the tales of adventure to Serpo by a band of American astronauts who were bent on knowing the truth about this planet which revolved around the faraway Star System called Zeta Reticuli. Their journey was so fascinating that I kept a 2-inch file on this subject as the report unfolded. Thanks to Victor Martinez and Bill Ryan for frequent posting of one report after another onto OMF until the entire report was over. At one stage, the revealer - Mr. Anonymous even promised to released some tantalizing photographs of those astronauts while they were sojourning on Serpo. But due to turf war within the Defense Inteligence Agency, the photographs were never released, much to the great disappointment of many at OMF. However, Bill Ryan subsequently disclosed to the membership that while he was attending an UFO meeting at Laughlin, he was covertly shown some interesting photographs - which among them was a picture of the Eben, the Eben script and what Bill described was a picture of a desert scene with rolling hills and the two suns setting behind them. Bill said this picture was very significant and he believed then that it must be a scene on the Serpo planet.

On one occasion, Bill Ryan disclosed at the then OMF that he was given an interesting information about a member of the Team to Serpo, but this person was only trained as a standby in case one in the Team of Twelve to Serpo pulled out. Bill approached the house and asked this person's wife to inform her husband that if he wished to talk regarding Serpo. However, the man was actually standing behind the door! The wife merely closed the door. Then Bill waited never by in case the member would change his mind and come forth to tell the story. Then this person was told by his minders that he should not meet with Bill nor tell him about the truth of Serpo on the pain of dire punishment....deprived of the pension! Hence, Bill Ryan was not given the chance to know more about the truth of Serpo by the powers-that-be which still controls much of the Serpo Adventure to this day. What a pity and how selfish the custodians of this information refuse to let the world knows more about conditions on Planet Serpo...!!!

This was how the entire disclosure of relationship between the twelve American travellers and the Ebens was first revealed in the fall of 2005 until OMF became defunct in December, 2011...! I had the previledge of knowing and accumulating a large amount of information in my 2-inch file. I welcome this book and rejoice in the fact that the entire information of Serpo is finally seeing the light of day for not only the American public but the citizens of this world. Let's hope that more interesting information will continue to come froth from the restless pen of Mr. Victor Martinez, the first person chosen to disclose this Serpo information. Cheers!

The author tells in an inspiring way how a dozen US soldiers went another world for an exchange program. Eben, a friendly gray race under AI control were used as a front for Nebu in infiltration of planets like Earth. Some of the soldiers choose to stay on Selpo (Serpo). Kasten also tells us interesting facts like the roots of nazism.
