# Danny Sheehan at Yale: claims of undersea bases, abductions and a hybrid programme

At a Yale event, attorney Daniel Sheehan claimed intelligence agencies knew of nonhuman bases in mountains and beneath the sea, as well as a hybrid programme. Three clips preserve his statements alongside the public testimony and documents available for comparison.

## At a glance

**What is known:**

Sheehan's Yale lecture is recorded; separate UAP testimony and records also exist.

**The claim or interpretation:**

He describes undersea bases and a hybridisation programme based on information he says he received.

**What remains open:**

The other material does not establish those bases or verify the hybridisation claim.

## A lecture on Yale's campus, not a Yale research finding

The distinction matters. This was a teach in organised by the Yale Student UFO Society and held in Linsly Chittenden Hall. Sheehan and Jim Garrison appeared for the New Paradigm Institute in a ninety minute session. The event is documented, but its location does not mean Yale University verified the claims made by its speakers. The programme was intended to bring UAP into multidisciplinary discussion alongside physics, philosophy and support for people who report encounters.

## Who Daniel Sheehan is

Daniel Peter Sheehan is a Harvard Law School trained American attorney with a long career in public interest litigation and nonprofit advocacy. One documented connection to the subject was his legal representation of Harvard psychiatrist John Mack, who studied people reporting encounters with non human beings and faced a faculty review. Sheehan is now chief counsel of the New Paradigm Institute, which campaigns for broad government release of UAP information. His legal background explains his focus on sources, secrecy and government accountability, but it does not itself authenticate the biological and intelligence claims in the lecture.

## The larger picture he presents

In the first part, Sheehan frames the phenomenon not as isolated lights but as a continuing presence involving several non human groups. He speaks as a disclosure advocate who believes the central question is no longer whether something exists, but who controls the information and what social change would follow its release. That is his stated position, not the conclusion of a public government report.

## Part 2: the base Sheehan places near Guadalupe Island

Sheehan says different species maintain bases in remote mountain regions and beneath the ocean floor. He points specifically to the area near Guadalupe Island, west of Baja California, and says the USS Nimitz carrier strike group was positioned to monitor activity there. In his account, the force tracked more than one hundred craft descending from space, entering the water and being followed by nuclear submarines. This is the series' most concrete claim because it provides a location, a military force and a pattern of movement that could in principle be checked.

## What Fravor and the lawmakers reported

In congressional testimony, David Fravor described USS Princeton radar tracking and his encounter with other pilots and a white Tic Tac shaped object in November 2004. He learned about the radar data from ship personnel; he described the airborne sighting firsthand. Tim Burchett reported a conversation with an admiral about underwater movement, while Eric Burlison and Anna Paulina Luna discussed a naval briefer's information. These are separate sources, with no public data connecting Nimitz to Sheehan's alleged Guadalupe base.

## The image that disappeared from Google Earth

An older Google Earth view shows Sycamore Knoll, a broad, flat topped seabed formation off Malibu near Catalina Island. Reports in 2025 said the detailed view had been replaced by a blurred or less detailed area. The original image matters because readers can see the exact formation that drove the discussion. It is not, however, the same location as the waters near Guadalupe Island identified by Sheehan. Both belong to the broader public conversation about anomalous activity off California, but they should not be presented as a single coordinate.

## Part 3: the series' most consequential allegation

Sheehan alleges that people have been taken involuntarily for decades, that sperm and ova are collected, and that embryos combining human and non human genetic material are created. He says the embryos are temporarily returned to human pregnancies, later removed and raised outside the human environment. He names short Greys, tall Greys and mantis like beings, then says US intelligence agencies know this is occurring and conceal it. The clip provides no DNA test, medical chain of custody or releasable government document by which the allegation can be verified.

## The chromosome detail that needs correction

The subtitles refer to 24 chromosomes in human sperm and egg cells. The standard human count is 23 chromosomes in each gamete, producing 23 pairs and normally 46 chromosomes after fertilisation. The line may reflect a slip of the tongue, a captioning error or an unexplained distinction, but as presented it does not match human genetics. Because the central claim concerns hybridisation, the discrepancy is material rather than cosmetic.

## Why the complete lecture still matters

The linked full lecture preserves the sources Sheehan names for his claims. Bases and hybridization require different material; the attached excerpts provide neither base tracking data nor genetic tests. Nimitz testimony and seabed imagery do not supply those missing records.

## Sources and context

**Editorial clarification**  ·  September 10, 2026
The body now matches the earlier clarification: Nimitz testimony, lawmakers’ statements and seabed mapping do not verify Sheehan’s base or hybridisation claims.

The event, More Things in Heaven and Earth, was held on September 27, 2024 on Yale's campus by the Yale Student UFO Society with support from the New Paradigm Institute and the Visible College. The complete lecture is public, and the three Alien Avi videos are excerpts from Sheehan's appearance. The 2004 Nimitz encounter is preserved in retired Commander David Fravor's formal statement to Congress. Representatives Eric Burlison, Anna Paulina Luna and Tim Burchett have also spoken publicly about claims or briefings concerning activity and possible bases beneath the sea.

The testimony, lawmakers’ remarks and seabed images concern different material. No released tracking data or documents establish an undersea base or connect one to the Nimitz encounter. The hybridisation allegation is separate and requires its own evidence.
