Some have claimed that the strongest UFO reports are too compelling to be dismissed as mere mistakes (e.g. Hanson, 2023). This has led others to ask what these strongest UFO reports are exactly. Hanson only provides two sources to back up his claim: a documentary by James Fox, titled The Phenomenon (2020), and a book by Leslie Kean, titled UFOs: Generals, Pilots and Government Officials Go On the Record (2010). Yet it is understandable if most people are skeptical toward these sources. After all, those who produce books and documentaries about UFOs may not be fully objective and dispassionate in their reporting. So it is only reasonable to ask for other sources of evidence.
As a skeptic toward Hanson’s claims myself, I have spent some time trying to see if I could find any instances of credible UFO reports. This post is meant to be a collection of the sources and reported observations I could find that seem to reach a certain threshold of credibility, at least in my view. To be clear, the threshold in question is not anything like “this is 100 percent trustworthy and true”, but more like “this seems credible enough to be worthy of further investigation/credible enough to cause us to take this issue more seriously”.
A general point that may be surprising to those who have not looked much into the UFO topic — and something that was quite surprising to me — is that a large number of UFO reports come from esteemed navy pilots with no pre-existing interest in UFOs. Likewise, there are many high-ranking US officials and former officials who take the issue seriously, and who have actively been pushing for further investigation. In other words, many of the key figures talking about UFOs are not the fringe conspiracy theorists that are commonly associated with UFOs in the public imagination, but instead surprisingly reputable people.
I share the following names and reports because I think it is helpful if people are better informed about them. After all, even if none of these reports pertain to any extraordinary phenomena, it still seems helpful if people are familiar with some of the alleged sightings and reports that constitute the basis for the modern UFO discourse. This way, discussion about the issue can at least proceed in an informed manner.
For some preliminary background on the issue, and on how the discourse around it has changed in recent years, it might be helpful to read the short NPR article “How UFO Sightings Went From Conspiracy Theory To A Serious Government Inquiry”.
People who have shared notable reports
The following are people who have shared what strikes me as fairly credible and update-worthy information:
- David Fravor, former US Navy commander pilot, witness of the Nimitz incident that reportedly involved a ~12 meter long “tic-tac” object. See e.g. his opening statement made under oath in a 2023 congressional hearing (text version).
- Interestingly, James McDivitt (Apollo astronaut) reported seeing a similar object in space in 1965: a white cylinder-shaped object with a “long white tube sticking out of it”.
- Likewise, a Danish airline pilot reported (around 32:00) seeing “the same” tic-tac object flying parallel to his airplane for around 20 to 30 seconds and then accelerating away near-instantaneously. (The incident took place over Italy, along the coast between Pisa and Rome, in 2018 or 2019.)
- Alex Dietrich, former US Navy lieutenant commander pilot (Nimitz witness)
- Chad Underwood, former US Navy pilot (Nimitz witness)
- Kevin Day, former US chief radar officer (Nimitz witness)
- Gary Voorhis, former computer technician at the USS Princeton (Nimitz witness)
- Ryan Graves, former US Navy lieutenant pilot
- Aldo Matić, radar operator in former Yugoslavia
- Graham Bethune, former US Navy commander pilot
- Jeremy Lane, former Royal Air Force pilot
- David Hastings, former airline pilot
- See also the similar report by pilot Malcolm Smith

- Alan H. Belmont, assistant director in the FBI in 1950-1961
- Donald Keyhoe, Marine Corps naval aviator and journalist
- Timothy Gallaudet, oceanographer and former rear admiral in the US Navy
- John Alexander, retired US Army colonel
- Scott Bray, former Deputy Director of Naval Intelligence
- See e.g. the 2022 Public US Congress UFO hearing, in which Bray also notes that “China has established its own version of a UAP [Unidentified Anomalous Phenomena] task force.” (See also “China military uses AI to track rapidly increasing UFOs”.)
- Sean Kirkpatrick, former director of the Defense Department’s All-Domain Anomaly Resolution Office (AARO)
- See e.g. the 2023 Subcommittee on Emerging Threats and Capabilities Hearing and the 2023 NASA UAP meeting
- In the latter video, Kirkpatrick says: “We see these [‘metallic orbs’] all over the world, and we see these making very interesting apparent maneuvers.”

Selected UFO footage
- Gulf Breeze sightings (1987-1990s)
- Footage from mass sighting in Mexico during solar eclipse (1991)
- Nellis Air Force Base UFO (1994)
- São Paulo glowing orb (1998)
- New York City glowing orbs (2010)
- A somewhat similar collection of orbs was observed and filmed in Greifswald, Germany (1990)
- Collection of footage of donut-shaped UFOs (2013-2024)
- Birds, satellites, plane, and UFO that changes direction (2018)
- USS Omaha incident (2019)
- There is also footage of the associated radar readings (the objects were tracked by two different radar systems), which at one point showed 14 different objects. One of the objects appeared to move at 138 knots (around 255 km/h) while another object appeared to be hovering in a stationary position.
- 2022 Fairfield County UFO
- UFO videos released in 2023 by the U.S. Customs and Border Protection (YouTube version)
- The 2013 video from Aguadilla in Puerto Rico is perhaps the most notable UFO video to date (the object was seemingly also caught on radar, and highly anomalous radar readings were associated with the event, including an apparent jump with a speed in excess of 2,500 km/h; see Coumbe, 2022, ch. 5). This clip has been public for a number of years, but it was officially released in 2023. The official release was presumably due to the UAP Disclosure Act of 2023.
Again, to be clear, this selected footage is included here because it appears puzzling and because it seemingly gives us tentative reason to take the issue more seriously. I am not claiming anything stronger than that.
High-profile people who consider the issue important
In addition to the stories and people listed above, it is worth noting that several high-profile US officials (both former and current ones) have taken the issue seriously. These include:
- Kirsten Gillibrand, US senator
- Marco Rubio, US senator
- Harry Reid, former US senator
- John Brennan, former head of the CIA
- John Podesta, White House chief of staff to Bill Clinton
- Christopher Mellon, former ‘Deputy Assistant Secretary of Defense for Intelligence’ in the Clinton and George W. Bush administrations
- Barack Obama and Mitt Romney have also made statements on the issue:
- Obama: “There is footage and records of objects in the skies. We don’t know exactly what they are. We can’t explain how they moved, their trajectory. They did not have an easily explainable pattern.”
- Romney: “I don’t believe they are coming from foreign adversaries. If they were that would suggest they have a technology that is in a whole different sphere than anything we understand, and frankly China and Russia just aren’t there, and neither are we by the way.”
In March 2024, the issue was also taken seriously and discussed in the European Parliament, led by Francisco Guerreiro.
Likewise, it is worth noting that various academics and intelligence analysts have taken the issue seriously. Besides Robin Hanson mentioned above (who has done various podcasts on the issue), these academics and analysts include:
- James E. McDonald, senior physicist at the Institute for Atmospheric Physics and a professor of meteorology at the University of Arizona
- J. Allen Hynek, professor of astronomy at Ohio State University, initial debunker who gradually changed his mind while serving as scientific advisor to various UFO studies conducted by the US Air Force
- Peter A. Sturrock, professor emeritus of applied physics at Stanford University
- Richard F. Haines, former researcher at NASA and associate professor of psychology at San Jose State University, creator of a large archive of UFO sightings
- Kevin H. Knuth, associate professor of physics and informatics at University at Albany
- Tyler Cowen, professor of economics at George Mason University
- Alexander Wendt, professor of political science at Ohio State University
- Marik von Rennenkampff, former intelligence analyst in the U.S. Department of State’s Bureau of International Security and Nonproliferation
- Daniel Coumbe, physicist, author of Anomaly: A Scientific Exploration of the UFO Phenomenon (review)
- Beatriz Villarroel, assistant professor at the Nordic Institute for Theoretical Physics in Stockholm
More broadly, in a survey conducted among US academics spanning 14 disciplines and 144 universities, a majority of respondents said that they were at least moderately curious about the topic of UFO/UAP. The survey also asked people whether they or someone close to them had observed anything of unknown origin that “might fit the United States government’s definition of UAP”, to which 18.9 percent said ‘yes’ and another 8.77 percent said ‘maybe’. Yet it should be noted that the survey was sent to nearly 40,000 academics by email, of whom only 1,549 answered, so there are likely strong selection effects in these results.
Recurrent patterns
Lastly, it is worth mentioning that there are some striking commonalities across many of the reports mentioned above. Specifically, the objects that are reported are often claimed to be:
- Almost or entirely silent
- Able to fly and navigate without any visible means of propulsion or steering
- Able to hover in a perfectly stationary position
- Able to accelerate rapidly and to travel at very high speeds (often above 10,000 km/hour), yet without causing a sonic boom
- Able to change direction near-instantaneously
From Iran and China to Peru and Brazil — and across time — these features are surprisingly recurrent in UFO reports (see also Knuth et al, 2019; Knuth, 2022). Another pattern is that the UFO reports are often connected to nuclear facilities (e.g. in Iran and in various incidents in the US, allegedly also in recent times). Moreover, the unidentified objects are frequently claimed to be orbs (in around 50 percent of recent reports), and they are typically reported to measure 1 to 4 meters in diameter.
It is difficult to know what to make of these patterns. Of course, there is good reason to be extremely skeptical of such a priori unlikely features, let alone the combination of many such features. But the fact that these features and abilities are often mentioned in UFO reports by professional aviators — people who are well aware that these are crazy unlikely and bizarre abilities — is arguably some reason to think that there really are objects that possess these abilities. At the very least, it raises the challenge of explaining why pilots across different nations and different eras would converge to report these same bizarre patterns. I myself am genuinely agnostic and puzzled.
