Researcher, American
Chris Lehto
Retired USAF F-16 Lieutenant Colonel who applies combat pilot expertise and crash investigation methodology to the analysis of declassified UAP footage.
Early life and background
Chris Lehto pursued his undergraduate education at the United States Air Force Academy, earning a Bachelor of Science in Chemistry-Materials Science — a rigorous scientific foundation that would later inform his data-driven approach to evaluating UAP footage. He subsequently earned a Master's degree in Aeronautical Science from Embry-Riddle Aeronautical University, one of the most respected aviation institutions in the United States. These credentials distinguish him from many figures in the UAP research space, where advanced degrees in relevant technical disciplines are relatively rare.
After commissioning from the Academy, Lehto entered the fighter pilot pipeline and qualified on the F-16 Fighting Falcon, one of the most versatile multirole fighters in the world. The F-16 is built around a sophisticated targeting pod system, and pilots who fly it regularly engage with exactly the kinds of infrared sensor outputs — FLIR imagery, digital zoom, atmospheric shimmer effects — that appear in the three most debated UAP videos released by the Pentagon between 2017 and 2020.
Military career
Lehto served 18 years in the United States Air Force, retiring in 2020 at the rank of Lieutenant Colonel (O-5). His career took him to postings across four continents: South Korea, Italy, Alaska, Turkey, Spain, and multiple stateside bases. The geographic breadth of his service reflects the international character of American air power commitments and gave him direct exposure to NATO operations and foreign military cultures.
One assignment stands out for its operational depth: he spent three years in Turkey as an exchange pilot, becoming fluent in Turkish in the process. Exchange tours embed American pilots in allied air forces and demand cultural adaptability and communication precision that carries over into analytical work. He was also deployed to Iraq for five months in 2006 during Operation Iraqi Freedom, logging combat hours in a high-stakes, information-rich airborne environment.
Among his specialist roles, Lehto served as an Electronic Attack Subject Matter Expert for the Aggressors — the USAF's adversarial training units that replicate enemy tactics to sharpen allied pilots. Aggressors require a deep understanding of how opposing sensor and radar systems operate, building a practical working knowledge of how detection technologies can both reveal and mislead. This background proved directly applicable when he began analyzing UAP sensor data years later.
He also commanded the U.S. Detachment at the NATO Tactical Leadership Programme (TLP) based in Spain, a multinational training organization where allied fighter pilots develop advanced tactical skills together. Leading the American contingent at TLP required managing international relationships, overseeing simulator contracts worth millions of dollars, and maintaining operational standards across coalition boundaries.
For four years, Lehto served as a certified crash safety investigator, formally reviewing Air Force accidents and conducting failure analysis. This role is particularly relevant to his post-retirement UAP work: crash investigation demands that you distinguish between sensor artifact and real-world anomaly, reconstruct events from incomplete data, and resist premature conclusions. The analytical discipline instilled by years of accident reconstruction is visible in how he approaches contested footage.
Lehto retired in 2020 and relocated to Lagos, Portugal, with his wife and three children.
Transition to public UAP research
His entry into the public UAP conversation was catalyzed by the CBS 60 Minutes broadcast of May 16, 2021, which brought the UAP topic to a mass American audience. He describes his deeper motivation as originating with Commander David Fravor's accounts of the 2004 Nimitz UAP encounter — the case in which an experienced F/A-18 pilot described a 40-foot white object behaving in ways that violated known aerodynamics. That incident and the associated FLIR1 video became one of his central reference points.
Feeling that the public deserved informed technical commentary rather than either credulous speculation or reflexive dismissal, Lehto launched the Lehto Files YouTube channel (@ChrisLehtoF16) shortly after the 60 Minutes segment. The channel quickly accumulated substantial viewership for its rigorous, jargon-accessible breakdowns of declassified footage.
Major contributions and analysis
Lehto's analytical method is deliberately low-tech in its inputs but systematic in its logic. He uses geometric construction — ruler and compass work, sketch-pad diagrams — alongside F-16 simulator programs to model flight envelopes, and sometimes literal household objects as scale references. He has explained that this kind of geometric reasoning is standard pilot training: every fighter pilot learns to triangulate distances, closure rates, and angular speeds using the information available in a cockpit. The three Pentagon-released videos (FLIR1, GoFast, and Gimbal) each involve F/A-18 sensors operating under specific flight conditions, and Lehto applies his understanding of how those systems behave to evaluate competing interpretations.
On the Gimbal video specifically — a 2015 recording made off the U.S. East Coast and widely considered the strongest piece of publicly available UAP footage — Lehto concluded that the object is approximately six miles from the recording aircraft, subsonic, and being closed upon by the F/A-18. In his analysis, the object's rotation and apparent thermal signature argue against mundane explanations such as a distant commercial aircraft or atmospheric lens artifact. He has described the Gimbal footage as what "a classic flying saucer of the 1950s" would actually look like if captured by a modern military targeting pod — framing it as potentially the single most important piece of UAP evidence in the public domain.
His central thesis, shared with former Deputy Assistant Secretary of Defense for Intelligence Christopher Mellon, is that the three authenticated videos have not been credibly debunked: conventional explanations (atmospheric lensing, parallax artifacts, sensor rotation, distant aircraft) are inconsistent with the recorded flight data when analyzed carefully. Mellon shared and amplified Lehto's video analysis on social media, lending it broader credibility within the UAP disclosure ecosystem.
His channel has hosted substantive interviews across the credibility spectrum. He engaged directly with Mick West, the prominent skeptic and founder of Metabunk, in on-camera debate — a willingness to confront serious counterarguments that distinguishes him from advocates who avoid adversarial scrutiny. Other notable guests have included Harvard astrophysicist Avi Loeb, FLIR sensor specialist Dave Falch, and various figures from within the UAP policy and research community.
Beyond video analysis, Lehto has been involved with SKY360, a citizen science initiative that deploys calibrated cameras and sensor arrays to systematically record and categorize aerial phenomena. The project aims to bring reproducible, instrumented observation methodology to UAP study — an approach that addresses the core evidentiary problem of UAP research, which is that nearly all evidence so far is anecdotal or of disputed provenance.
He also hosts the Lehto Files podcast, available on Apple Podcasts, Spotify, and Spreaker, which covers UAP policy developments, interviews experts and self-described whistleblowers, and tracks legislative milestones such as the UAP Disclosure Act and reporting from the All-domain Anomaly Resolution Office (AARO).
Reception and criticism
Lehto occupies a carefully maintained middle position in UAP discourse. He is consistently more credible than channeling contactees or anonymous insiders: his credentials are verifiable, his reasoning is public, and he actively invites critics to engage. Metabunk users have engaged seriously with his Gimbal analysis, with debates centering on whether his distance and speed estimates are defensible given sensor geometry — a technical-level exchange that rarely happens around more sensationalist UAP content creators.
His background as a crash investigator is frequently cited in his favor. Accident investigation methodology requires distinguishing real events from instrumentation artifacts, maintaining evidentiary chains, and resisting confirmation bias — all directly applicable skills. Critics note, however, that expertise in flying and cockpit sensors does not automatically translate into expertise in optical physics, atmospheric optics, or signal processing — the disciplines most relevant to evaluating what targeting pod video actually shows at specific range and atmospheric conditions.
His positioning as a "debunker debunker" — someone who challenges skeptical explanations rather than positively asserting alien origin — gives him rhetorical flexibility but also means his central claim is ultimately negative in form: he argues that conventional explanations are insufficient, not that he knows what the objects are. That epistemic humility is intellectually defensible and arguably the only honest position given the available evidence, though it also means his analyses cannot be falsified by any single counter-explanation.
Some within the UAP community have noted that his relocation to Portugal and his relatively low media footprint compared to figures like Luis Elizondo or David Grusch limits his influence on institutional-level conversations. Nonetheless, his technical literacy and good-faith engagement with skeptics have earned him consistent respect across otherwise adversarial camps.
Legacy
In the context of the post-2017 UAP disclosure era, Lehto represents a category of commentator that has become increasingly important: credentialed military professionals who use accessible media formats to apply genuine technical expertise to publicly available evidence. Before figures like Lehto, UAP discourse was dominated either by civilian enthusiasts with limited aviation knowledge or by credentialed skeptics dismissing the phenomena. The emergence of retired military pilots and intelligence officers willing to engage openly — and to say, on record, that certain footage defies their professional explanation — has materially shifted the tenor of the conversation.
His YouTube channel and podcast provide entry points for audiences who would not engage with traditional UFO literature but follow veteran and military-themed content. By framing the UAP question as a matter of aviation safety, national security analysis, and government accountability rather than extraterrestrial mythology, he has helped normalize serious engagement with what was long considered a fringe topic.
His involvement with SKY360 also points toward a more scientifically respectable future for UAP study: rather than relying on leaked or anecdotal footage, the goal is systematic observation with calibrated instruments — an approach that would allow independent verification and statistical analysis of aerial anomalies. Whether or not any of those anomalies ultimately prove to have exotic origins, the methodological direction represents real progress.
Lehto remains an active voice as of 2026, continuing to cover congressional developments, new declassified material, and the evolving institutional landscape around UAP research in the United States.
Notable claims
- The Gimbal video (2015, USS Theodore Roosevelt) shows an object approximately six miles from the F/A-18, subsonic, and unidentified by any conventional explanation Lehto has been able to construct using targeting pod geometry and flight dynamics analysis.
- The three authenticated Pentagon UAP videos — FLIR1, GoFast, and Gimbal — have not been credibly debunked; competing conventional explanations (atmospheric lensing, parallax artifacts, sensor rotation) are inadequate given the recorded flight data.
- Fighter pilot testimony from the Nimitz incident (2004) is credible precisely because experienced combat aviators have the professional incentive to identify rather than misidentify unknown aircraft: threat identification is a core survival skill.
- UAP represents a genuine aviation safety issue independent of its ultimate origin, requiring systematic institutional response rather than dismissal.
- Citizen science instrumentation networks such as SKY360 offer a path toward reproducible, verifiable UAP data collection that anecdotal sightings and leaked video cannot provide.
