11 Incredible Claims Made by UAP Whistleblowers

11 Incredible Claims Made by UAP Whistleblowers

Welcome to WatchMojo, and today we’re counting down our picks for the most mind-boggling allegations made by UAP whistleblowers.

Edgar Mitchell's Extraterrestrial Technology Claims

In 1971, Apollo astronaut Edgar Mitchell spent approximately nine hours working on the lunar surface, earning him the distinction of being one of only 12 people to walk on the moon. Mitchell boasted an impressive resume, having served in the Navy before being selected to work at NASA. But, to the surprise of some, he later became a ufologist. Mitchell went on record multiple times to say that he was confident that many of the reported UAP sightings since the 1940s were likely extraterrestrial visitors. He also asserted that technology provided by extraterrestrial sources had proven very useful to the U.S. government in the past, but that the government was purposefully covering up the existence of such technology.

Paul Bennewitz' Dulce Base Allegations

In the mid-1970s, a bizarre series of cow mutilations perplexed ranchers throughout the U.S.. Theories to explain the killings ranged from there being a satanic cult active across the country… to the cows being linked to top-secret government operations. As the cases mounted, rumors of extraterrestrial involvement grew. In response, the businessman Paul Bennewitz started a self-funded study into UAP activity. He recorded several strange radio transmissions and unexplainable lights above Kirtland Air Force Base. Later, based on his research, Bennewitz became convinced there was a secret underground facility jointly operated by aliens and humans near Dulce, New Mexico. The area - dubbed the Dulce Base - quickly emerged as a hotspot for many of the most compelling UFO sightings.

Clifford Stone's Extraterrestrial Retrieval Work

In recent times, we’ve seen headlines worldwide relating to prominent ex-military figures coming forward to reveal the truth. But, actually, this isn’t the first wave of testimonies like this. In the early 2000s, the retired Army Sergeant Clifford Stone became one of the UFO community’s loudest voices - at times collaborating with the famed ufologist Steven Greer and his organisation, the Disclosure Project. Stone claimed that, during his time with the Army, he visited numerous UFO crash sites and saw both living and deceased alien beings. He reportedly cataloged more than 50 distinct alien species as part of his work. Even more shocking - Stone claimed that many of the lifeforms he observed were humanoid in appearance and could perhaps walk among us without detection.

Gary McKinnon's NASA Hack

For 13 months in the early 2000s, Scottish hacker Gary McKinnon gained access to as many as ninety-seven U.S. military and NASA computer systems. His actions were a huge deal at a time when America was on red alert for security breaches. McKinnon was searching for proof of UFO activity and of government knowledge of alien technologies. And he reportedly found what he was looking for in a file labeled “Unfiltered”, which (McKinnon says) contained satellite images and photos of alien spacecraft. Even more shocking, McKinnon claims to have uncovered classified military personnel documents listing “non-terrestrial officers”, as well as evidence of the government’s suppression of free energy technologies. But before he could download anything to his personal computer, he was noticed on the system and his connection was cut.

Philip Corso's Roswell Account

In 1997, a book by lieutenant colonel Phillip Corso - titled “The Day After Roswell” - was published. In it, Corso discloses several shocking secrets about his involvement in the infamous Roswell incident. According to him, aliens did, in fact, crash in Roswell in 1947, and the government covered up all of the evidence. At the time of the Incident, Corso was stationed at Fort Riley in Kansas. Following the Incident, he was allegedly assigned to a secret military group tasked with collecting information about alien technology recovered from the crash site. This intel was subsequently used in the development of several groundbreaking innovations, such as fiber optics and Kevlar. Corso also claimed that, while working, he stumbled upon a perfectly preserved alien body concealed within a wooden case.

David Fravor's Tic Tac Encounter

Testifying before Congress in 2023, retired fighter pilot David Fravor detailed his 2004 encounter with a strange, fast-moving flying object off the coast of southern California. At the time, Fravor was the commander of the F/A-18F squadron on the USS Nimitz, an aircraft carrier in the US Navy. On November 14, 2004, he detected a potential target and decided to investigate… especially as another ship, the USS Princeton, had been tracking similarly unusual activity in the same area, just two weeks beforehand. The now-infamous object that Fravor witnessed far exceeded the known aeronautical capabilities of the time. He estimated that it was around 40 feet long. It was oval-shaped, completely white without any markings, and it didn’t have wings. When Fravor went in for a closer look, however, the object zoomed away so quickly that it seemed to disappear altogether.

Luis Elizondo and the Advanced Aerospace Threat Identification Program

Beginning in 2009, Luis Elizondo was reportedly recruited to work for the US government in the top secret, now-defunct Advanced Aerospace Threat Identification Program (or, AATIP). The official purpose of AATIP was to investigate UAP sightings and activity and, from 2010 until 2017, Elizondo claims to have served as its director. Before Congress in 2024, Elizondo testified that the government had secretly experimented on materials and technology gathered from non-human craft. He further alleged that the government’s extreme secrecy concerning the research had led to “grave misdeeds”, including career-ending threats leveled against anyone who agreed to give classified testimony about UAP encounters.

Jake Barber’s UAP Retrieval Footage

After a surge in UAP whistleblowing in 2023 and 2024, another big story landed in January of 2025. The former US airman Jake Barber was at the center, when he spoke to Ross Coulthart for NewsNation, revealing that he’d personally worked on secret UAP retrieval missions. His claims were accompanied by a short piece of footage, showing an egg-shaped UAP, as seen from the military helicopter tasked with retrieving it. Barber’s testimony went further still, as he also alleged that America runs a secret team of psionics, whose role it is to find and communicate with UAP. Psionics are a select group of people, said to have psychic-like abilities. Their role essentially amounts to remote viewing, something that it’s long been rumoured that the Pentagon is involved with.

Bob Lazar's Area 51 Revelations

In 1989, Bob Lazar achieved international infamy when he claimed that he’d previously worked as part of a top-secret government operation at Area 51. He says that, throughout the ‘80s, he assisted with the reverse engineering of alien technology, particularly inside a facility known as S-4. He claims to have witnessed alien spacecraft and alien bodies, as well as the development of anti-gravity technology made possible through the use of a mysterious substance known as Element 115. Many of Lazar’s revelations have long come under scrutiny, and there are no records of his purported links to the government or military. But Lazer insists that that’s only because those records have been erased.

Jesse Marcel Jr.'s Roswell Debris Memories

As the first Air Force officer to investigate the 1947 Roswell Incident, Jesse Marcel Sr. is inextricably tied to UAP lore. The official story provided by the government to explain Roswell was that a weather balloon had crashed in the area. And, for a long time, that story went uncontested… until Marcel came forward in the late 1970s with his own account. In short, he believed that what he observed in 1947 was not of this world. The legend was added to by Marcel’s son, Jesse Marcel Jr., who subsequently claimed to remember his father bringing home debris from the crash site. Marcel Jr. is on record claiming that, among the items his father retrieved, there was a purple beam covered in unusual hieroglyphics.

David Grusch's Retrieval Program Testimony

During the 2023 Congressional hearing on UAPs, the former Air Force intelligence officer David Grusch testified that the government had conducted highly secret alien retrieval operations for decades. Grusch, who claims to have interviewed at least 40 individuals in relation to the matter over a four-year period, alleged that the U.S. was also in possession of non-human biologics and numerous alien spacecraft. When questioned about how the top-secret retrievals operated, Grusch asserted that they were “above congressional oversight” and funded through covert and dishonest means. Grusch has long maintained that he’s in possession of further information to support his bombshell testimony. However, much of that information is, at the moment, too sensitive to publicly disclose.
