NHI USOs: Transmedium Craft and Bases
A Brief Overview from an Experiencer’s Point of View
© By K. Wilson
Based on verbal and published accounts by NHI-ET Experiencers and a few military witnesses, active water based locations for NHI or Extraterrestrial activity in the U.S. appear to include, but are not limited to, the Great Lakes region, the Hudson River Valley and the Gulf of Mexico. I am aware of a few in the Arctic and Antarctica, Australia and Europe. However, and of particular note, Richard Dolan’s latest book, “A History of USOs: Unidentified Submerged Objects: Volume 1: Beginnings to 1969,” comprehensively addresses USOs and Transmedium UAP-UFO sightings occurring in the United States and other countries and regions. With Volumes II and III on the horizon, I think Richard Dolan is meticulously demonstrating that USOs are EVERYWHERE! I have only just begun reading his new book, so for this article, I will stick with what I have learned from the standpoint of my own personal encounters and people and cases related to USOs that I have read about. (1)
Contact along the Gulf of Mexico
When you see the term Transmedium, think of water, air, space and more… I’ll get to the “more” in a few paragraphs. In the not too distant past, some of the areas where U.S. witnesses described Extraterrestrial appearing transmedium craft entering and exiting large bodies of water include the Gulf of Mexico. There are several well investigated Contact cases which have occurred along the Gulf Coast.
1973: The Year of the Humanoids
One well known 1973 case involved Charles Hickson and Calvin Parker of Pascagoula, Mississippi, which eventually yielded the publication of four books. Thanks to Philip Mantle and Dr. Irena Scott, we have since learned of other NHI-ET Experiencers related to the Pascagoula Case. These individuals also experienced Contact in the same (or very close to the same) location as Hickson and Parker, and during the same timeframes. This additional research involving these other witnesses and Experiencers indicates this was a “multiple abduction” that occurred. Since other people involved appear to have been life-long Experiencers it has been suggested by Philip Mantle and Dr. Scott that Charles Hickson and Calvin Parker might not have been the original intended subjects or targets if you will, of the “abduction.” To me personally, this additional information makes the events surrounding Hickson and Parker’s original NHI encounter more logical now. It is so important for witnesses to know, that no matter how old a case is it’s never too late to come forward with your information, no matter how insignificant you think it may be. (2-6)
Over 60 People Reported Sightings in and around Gulf Breeze, Florida: Including me!
Another widely publicized case is that of Ed and Frances Walters, who published their experiences in “The Gulf Breeze Sightings.” Even if you are skeptical of Ed Walters’ account of his events, the Gulf Breeze Sightings and associated ET-NHI contact, stand on their own as one of the best documented “UFO-UAP” events in the United States due to the number of other identified and investigated witnesses to the many sightings and NHIs seen. For those in doubt, you must read “UFOs are Real: Here’s The Proof” by Bruce Maccabee and Ed Walters. There were at least 60 other people who reported sightings during the same time period as Ed and Frances Walters’ sightings.
While I cannot publicly identify every witness I was aware of who was living nearby at the time and were experiencing Contact, I can say that several of my own experiences, as well as my husbands, (and people I knew at the time) had NHI experiences that occurred within 40 miles of Pensacola, Florida; some of these also involved seeing unusual craft entering into and rising out of the water. Jim Sparks is another well known Experiencer whose encounters occurred along the Florida Coast and he published his experiencers with NHI in his excellent book titled “The Keepers.” (7-11)
USOs - Unidentified Submersible Objects
Another active geographic location for UAPs is the Hudson River Valley. Several books about this specific region and UFOs or UAPs have been published dating back to 1982 with actual sighting reports dating back to the 1960s. The Great Lakes region is another large inland water source for transmedium USO reports (with six references by Richard Dolan prior to 1969). This is logical when one considers the geology and physiography of these areas. The age, structure and composition of this region makes it a perfect location for technologically advanced Beings to “hide” from peering eyes, or even live long-term incognito in very deep underwater habitats. (12-17)
NHI could be dwelling deep within crevasses and large caves while staying out of site from technological eyes such as advanced undersea radar and space satellites. Since I’m fairly certain some of our world’s Navy’s already know where some of the undersea hotspots are located, I have a feeling others will discover them soon due to the amount of interest and the number of permits being requested and issued by the International Seabed Authority or ISA. We are in the process of mineral mining our most precious resource: our Oceans and I fear this may be one of the “warnings” about our planet NHI Beings have been relaying to Experiencers and Contactees for decades. (18-20)
My Own Transmedium Experiences
During my lifetime, I have had several encounters during which the NHI craft I was aboard went underwater or landed on a large object in the ocean. One of these appeared to be a somewhat stripped down naval ship as well as what appeared to be a “NHI” Grey-Humanoid base situated next to a large body of water. This illustration is from an experience I had in 1992 involving my experience on a cigar shaped craft which landed on a base with other craft of the same type. I was also shown the inside of the hangar where one of these craft was hovering over or floating in water as if it were “docked.” (21)

In 2008, I had an encounter with a female Hybrid Humanoid who stood approximately 5’ 6” and had dark blonde hair. Her eyes were similar to human eyes, but were the size of the Greys’ in that they were large and turned up slightly on the outer edges. When I asked her where she was from, she replied,
“I am from under the ocean.”
I took her response to mean exactly what she implied; she and other NHI like her live under the Ocean which is not so far fetched when you look at the size and technical abilities of their craft. Notice she did not say “underwater.” She said “I am from under the Ocean” itself.
The space under an ocean is called the ocean floor. An ocean's floor can consist of continental shelves, oceanic trenches and deep sea plains. Beneath the ocean floor is the Earth's crust and upper mantle. What lies beneath depends on whether you are over continental crust or oceanic crust. Beneath this, is the mantle consisting of approximately four more layers before one reaches the outer core of Earth, which is liquid and the inner core of Earth, which is solid. Therefore, the female Being could have been telling me she, and others of her kind, live within the Earth's crust which might allow a living area to a depth of approximately 10 to 200 kilometers or 6.2 to 124 miles.
Transmedium Craft: Water, Air, Space and Solids
A little over 70% of our planet is covered in water. The Earth’s five oceans cover approximately 129,432,254 square miles of our planet, which is an enormous amount of area in which NHIs could be concealing themselves. If over 8 billion humans can live on land areas smaller than this, it isn’t such a stretch to reason that these Beings can exist on the same planet as we do and still not be seen very often. If they can fly their craft in space, there is no reason why they cannot navigate our oceans as well. This is where the term transmedium comes from: it means traversing water, air and space; and speaking from firsthand experience, I know their craft can also traverse solid materials of their own design as well as certain types of rock.
Earth’s oceans conceal mountains, volcanoes, oceanic trenches, submarine canyons, oceanic plateaus, and abyssal plains. The abyssopelagic or abyssal zone is a chasm, a deep void measuring as deep as 20,000 feet (probably deeper). These deep abysses can easily conceal most of the undersea activities of USOs or unidentified submersible objects.
Large bodies of water are a logical choice for NHI Beings to inhabit, at least while they have business here on Earth. However, we already know they have been here for at least as long as humans, and have probably been living, at least temporarily, in our oceans for the same amount of time. I often wonder if perhaps whales (who have probably been here longer than NHI) and other ocean mammals communicate with NHI on a regular basis. And, when they come up for air, I wonder what they must think when they look at humans in their boats, with their fishing apparatuses and worse.
Undersea UFOs: The Lost Evidence

In the television program “Undersea UFOs: The Lost Evidence,” during a Naval Exercise called Operation Mainbrace, a sailor took photographs through the periscope of his submarine of an extraterrestrial appearing craft that had just emerged from the sea. It surfaced and then went back under the water and then rose up again. It almost appeared to be distracting the fleet of ships and submarines away from something, perhaps an underwater base or other craft that were also underwater in the vicinity of the exercise. It is also possible that this was a deliberate sighting and the Beings wanted the fleet to see them. Perhaps it was their way of “showing force” just as Operation Mainbrace was “showing force” to the (former) Soviet Union, and in their own “backyard.”
Another sighting covered during this episode involved a Russian nuclear submarine crew who witnessed 6 disc shaped craft that rose from the sea. The six craft flew in a triangle formation and headed directly toward them at 265 miles per hour. The craft were never identified as being terrestrial, i.e., any known craft of the time.
The Swimmers of Lake Baikal
In Siberia in 1982, seven Russian scuba divers were exploring Lake Baikal which is the largest fresh water lake by volume in the world. During their mission, they encountered Non Human appearing Beings swimming underwater. They were described as “larger than humans” and appeared to be approximately 9 feet tall. They had some sort of membrane-type head covering over their heads and wore silvery colored bodysuits. According to the artist’s interpretation, their feet had four wide “toes” with the larger toe being angled outward similar to an opposing thumb.
When the Russian scuba team tried to capture one of the ET appearing Beings with a net, some type of force – perhaps of a concussive nature – forced the Russian divers upward to the surface at a high rate of speed which led to the deaths of three of them. The other four were said to have been so shaken that they could not speak about what occurred. It is suspected that they were probably silenced by their government, just as American military and other individuals are forced to remain silent on the NHI-ET issue.
U.S. Navy’s Ultimate Fantasy Underwater Submarine Bases
Excerpts from Steve Weintz of “National Interest”
“Did the Navy ever actually pursue the Rock-Site concept at Point Sur or elsewhere? A 1971 study discussed various methods of sea-floor excavation, but by then most man-in-the-sea development was classified.”
“As late as the 1960s, Navy technicians and their families at Point Sur monitored undersea listening posts used to track Soviet subs. According to one legend, it wasn’t merely hydrophones the Navy ran from Point Sur, but submarines themselves based in giant man-made caverns dug into the rock.”
“It was in this environment that C.F. Austin of the China Lake Naval Ordnance Test Station proposed the Rock-Site concept: manned undersea installations excavated into the rock of the seafloor. By applying well-understood principles employed for decades by the mining industry, Austin proposed that large bases could be constructed and operated anywhere suitable bedrock occurred in the ocean, at any depth.”
“In the 1970s the Los Alamos National Lab investigated an atomic rock-drilling concept called the Nuclear Subterrene, which like Rock-Site sounds like something out of Johnny Quest, but also really happened. One wonders what might have happened had the Navy put its nuclear expertise to work drilling holes in the ocean floor.” (ed. or maybe they did?)
“The Rock-Site concept also bore much in common with NASA’s designs for underground moon bases. Very likely all three concepts - invulnerable bastions, space outposts and ocean bases - would have shared solutions to issues ranging from environmental control to crew morale.” - Steve Weintz of "National Interest"

UFOs and Water: Physical Effects of UFOs on Water through Accounts by Eyewitnesses
By Carl W. Feindt
(Dedicated to Richard H. Hall)
Carl Feindt’s interest in water-related UFOs (USOs) was preceded by his fascination with aircraft. As a boy growing up in New York City during World War II, he carved balsa replicas of aircraft, and in his teens flew model aircraft. He followed his passion and became a cadet in the Civil Air Patrol. After graduating from high school, he went on to study aircraft engineering at the Academy of Aeronautics in New York City. Following two years of service in the Air Force, he was forced to return to civilian life due to a family hardship. He joined a major airline where he worked in customer service for over three decades.
Upon retirement he was interested in becoming active in Ufology, about which he had been reading since the early 1960s. When Jan Aldrich, a UFO researcher, asked for volunteers to do local newspaper searches, Carl began an eight-year study of microfilm rolls at the University of Delaware, exhaustively covering the years between 1923 and 1967. To his amazement, he found approximately 750 UFO-related articles in the Delaware newspapers – all this from the second smallest state in the United States!
Intrigued by the fact that aircraft, as we know them, cannot emerge from water or submerge into water, he started assembling water-related UFO cases in 1998. He continues to conduct research into this aspect of the UFO mystery, which has grown into his increasingly large database and website, and he is a recognized authority in the field of water-related UFO research.
Carl has appeared on the History Channel documentaries, “Deep-Sea UFOs” and “Deep-Sea UFOs: Red Alert” and has been a guest on numerous radio talk shows nationally. He is a well-received lecturer in the United States and Canada. His 2006 award-winning paper, “Physical Influences of a UFO on Water” is available on his website and on DVD.
Carl William Feindt Obituary
Carl William Feindt, son of Charles and Hanna Feindt, passed peacefully in his sleep at the age of 81 on April 21, 2019.
From the time he was a boy, Carl was fascinated with flight. He became a cadet in the Civil Air Patrol and worked tirelessly throughout his career at Delta Airlines, where he was respected by customers, peers and management as dependable and capable. His curiosity regarding the extraterrestrial culminated in the pride of his later years that cemented his place in ufology: a book proposing a theory for how UFOs navigate air and water as based on decades of research.
Carl is survived by his sons, Jeffrey and Andrew and his younger sister, Helen Jatzen.
A Viewing will be held on Monday, April 29, 2019 at Gebhart Funeral Home, 3401 Philadelphia Pike, Claymont, DE 19703, from 11:00 a.m. until 12:00 p.m. Burial will follow in Lawn Croft Cemetery, Linwood, PA. (gebhartfuneralhomes.com)

The other “USO-logist”: Carl Feindt died
Posted on April 5, 2020 by Marco Bianchini
There are those that used to be called “pen friends,” people far away, whom you will never see in person and you have never had a face-to-face exchange with.
Carl William Feindt was one of those for me. We have corresponded for years and exchanged dozens and dozens of USO sighting reports. Yes, USOs: Unidentified Submerged Objects were the link between the two of us.
I can almost say that perhaps we have long been the only two active ufologists in the world who had specialized on “UFOs in the water”, and that’s why each new USO report either of us found was immediately sent to each other.
Who was Carl W. Feindt? From an early age he was such an aircraft enthusiast that he became a cadet in the Civil Air Patrol. After graduation, he studied aeronautical engineering at the New York City Air Force Academy and after two years of service in the USAF he returned to civilian life because of what he called “family difficulties.” He did not abandon his youthful passion, however, and so he worked for more than 30 years in customer service for a major airline.
After his retirement, he became actively involved in ufology, which had been an interested reader of since the early 1960s. Starting with Jan Aldrich’s Project 1947 research, in about eight years Carl viewed University of Delaware microfilmed newspaper collections for the years 1923-1967 and uncovered about 750 UFO-related items in that second smallest state of the USA.
He then became interested in sightings of UFOs surfacing from or submerging into water, and thus he created the world’s only specialized website on this subject (www.waterufo.net).
