Unidentified Submerged Objects

Unidentified Submerged Objects

A History of USOs: Unidentified Submerged Objects (Volume 1: From the Beginning to 1969) by Richard M. Dolan is the first installment in a groundbreaking three-volume series that explores the fascinating and often unexplained phenomenon of USOs—Unidentified Submerged Objects. This meticulously researched book delves into the earliest reported sightings of mysterious objects observed in oceans, lakes, and rivers, spanning centuries and covering 178 carefully documented cases up to 1969.

Dolan’s work is both a historical and scientific inquiry, examining accounts that have often been overlooked or forgotten. With a keen eye for detail, he places these encounters within a broader historical and technological context, raising questions about the nature of these enigmatic objects. Are they advanced technology from unknown civilizations, natural phenomena, or something else entirely? This volume sets the stage for understanding the long history of USO encounters, laying the foundation for the rest of the series.

The book is enriched with maps by the author and illustrations by Allan Lavigne, providing a visual dimension to the narratives. Dolan’s research draws from a wide range of sources, including military reports, eyewitness accounts, and historical records, all analyzed through a detailed system that evaluates factors such as time, location, shape, color, and witness credibility. This methodical approach allows readers to identify patterns and themes that emerge across decades and continents.

Volume 1 is not just a collection of stories; it is a thought-provoking exploration of the unknown, challenging readers to reconsider their understanding of the oceans and the universe. Whether you are a skeptic, a believer, or simply curious, this book offers a compelling journey into the uncharted depths of our planet—and beyond.

Bio

Richard Dolan is a leading researcher, historian, and writer on the subject of UFOs.

He is the author of two volumes of history, UFOs and the National Security State, both ground-breaking works which together provide the most factually complete and accessible narrative of the UFO subject available anywhere. He also co-authored a speculative book about the future, A.D. After Disclosure, the first-ever analysis not only of how UFO secrecy might end, but of the all-important question: what happens next? Richard is also the author of UFOs for the 21st Century Mind, a fresh treatment of the entire subject. In it, he discusses the important sightings, the encounters, the politics, the cover-up, ancient aliens, the bizarre science, disclosure, and offers advice on being both critical and open-minded in today’s world. More recently, Richard has written a series of booklets developed from select lectures on such topics as the idea of a secret space program and UFO secrecy and disclosure in the Trump era.

In addition to his UFO work, Richard wrote and hosted a series on the phenomenon of false flags for Gaia Television. This ten-episode series is groundbreaking as the first historical perspective of false flags through the ages, events in which governments or other agencies committed horrible and traumatic acts which were then blamed on other parties in order to justify and pursue certain objectives. Richard is currently researching and writing the first-ever history of false flags, with a strong focus on the 20th and 21t centuries.

Since 2012, Richard has hosted a weekly radio show, The Richard Dolan Show, on KGRA radio, and currently offers audio podcasts for members of richarddolanmembers.com. He has been featured on numerous television series and documentaries, including Ancient Aliens, Hangar One: The UFO Files, Close Encounters, and many others. He is also a frequent guest on Coast-to-Coast AM with George Noory.

Prior to his interest in UFOs, Richard completed his graduate work at the University of Rochester, where he studied U.S. Cold War strategy, European history, and international diplomacy. Before that, he studied at Alfred University and Oxford University, was a finalist for a Rhodes scholarship.

But for the past two decades, Richard has been a dedicated student of all things related to UFOs, steadily expanding his interests within that topic from his initial focus on government documents and the cover-up. Now his interests include it all, from the deepest aspects of the coverup, to contact and abduction, the science behind the phenomenon, how the phenomenon has affected world culture, his theory of a breakaway civilization, the possible relationship of artificial intelligence and biotechnology to the UFO phenomenon, and the implications of the end of secrecy, that is, the world After Disclosure.

Today, there is no aspect of the phenomenon Richard won’t study. He continues to look forward to exploring this topic in all its depth, a topic he believes opens our doors of perception, challenging us to see the world differently and more clearly.

In addition to his research, Richard’s company, Richard Dolan Press, actively publishes innovative books by authors from around the world, which can be visited at richarddolanpress.com.

This week I'm reading from Preston Dennett's book 'The Healing Power of UFOs, 300 True Accounts of People Healed by Extraterrestrials'.Are ETs healing humans?The answer, of course, is yes! In this landmark book, The Healing Power of UFOs, leading UFO researcher, Preston Dennett, presents a fascinating compilation of more than 300 cases of people who have been healed by extraterrestrials. Supported by firsthand eyewitness testimonies, stretching back more than 100 years to the present day, coming from across the United States and the world, this book proves that healing humans is one of the primary alien agendas on our planet. Verified by doctors and leading UFO researchers, the UFO healing cases represent incontrovertible evidence of UFO reality. Preston Dennett began his research into UFO healings in the early 1990s. His first book, UFO Healings (1996, Wild Flower Press) was the first book published on the subject, and presented more than 100 cases. This new volume presents the original cases (with new information) plus 200 more, many of which have never been published before. Preston Dennett has been documenting and researching healing cases for more than 25 years and is the world’s leading expert on UFO healing accounts. This landmark book is the culmination of his research and settles the question once and for all that medical healings as the result of a UFO encounter do actually happen.The healings include a wide variety of conditions. Injuries and flesh wounds, colds, flu and infections, serious diseases--all have been cured by ETs. Inside you will find:•More than 70 healings of injuries.•More than 50 healings of colds, minor illnesses and ailments.•More than 120 healings of serious illnesses and chronic diseases.•More than 40 healings of cancer.•Cases involving “health upgrades.”•Cases involving healings of animals and even plants.•A study of the connection between UFO abductions and psychic healing.•Accounts in which people have been “rescued” by ETs.•A study of miraculous cures from angels, NDEs, OBEs, lightning strikes, past life therapy, Native American ceremonial healings and more.•Evidence that our governments have obtained UFO healing technology and are using it for themselves.Who is being healed and why? What types of ETs are doing the healing? How are these healings being done? Are ETs our friends or foes? This massive 500-page book dives into the heart of the phenomenon and answers all these questions and more. Ignored for far too long, the UFO healing cases show a positive aspect to a phenomenon that has been saturated with disinformation for decades. The truth can no longer be denied. The aliens have arrived and as this book will show, one of their primary missions is the healing of all humanity.Bio Preston began investigating UFOs and the paranormal in 1986 when he discovered that his family, friends and co-workers were having dramatic unexplained encounters. Since then, he has interviewed hundreds of witnesses and investigated a wide variety of paranormal phenomena. He is a field investigator for the Mutual UFO Network (MUFON), a ghost hunter, a paranormal researcher, and the author of 30 books and more than 100 articles on UFOs and the paranormal. Several of his books have been Amazon UFO bestsellers.

It’s not some ‘flying craft’ but it’s pretty damn close, and it raises so many more questions than it answers.Here you will find detailed first-hand accounts of those involved, the best images of the crash debris available to date, up-dates from those same sources, how and where the original 25-year anniversary documentary was produced back in 2008, and hopefully marvel at how, in this day and age, physical evidence can still remain a mystery over four decades, the boundary of two centuries, and the turning of a new millennium.If you own a collection of books covering the entire UFO phenomena then you need this last chapter in order to add the closing pages to the strange history that you possess.The Llanilar UFO crash in Wales.
