“All the Skies That Are Fit to Print”
A night watchman filmed the same object returning across two years. Turkey’s official scientific body examined the footage and declared it could not be explained. The case has never been debunked.
Most UFO sightings happen once. A light in the sky, a shape that cannot be identified, and then it is gone. The Kumburgaz case is different. Over two years — from 2007 to 2009 — the same object returned to the same location on the Marmara Sea coast near Istanbul, Turkey. It was filmed each time by the same witness, using the same camera, from the same vantage point. By the time the footage came to international attention, it represented the most sustained, multi-session video record of an unidentified aerial object ever captured by a civilian witness. Turkey’s government science body examined it and could not explain what it was. It has remained unexplained ever since.
Yalcin Yalman was a night watchman at a holiday compound in Kumburgaz, a seaside district on the southern shore of the Marmara Sea, approximately 35 kilometres west of Istanbul. In May 2007, he first observed an unusual object hovering low over the water at night. He retrieved his video camera and began filming. The object was not a conventional aircraft. It made no sound that matched any known propulsion system. It moved in ways that did not correspond to helicopter, plane, or balloon behaviour. Yalman filmed it for as long as it remained visible, then reported what he had seen.
The object returned. Not once but repeatedly. Across the summers of 2007, 2008, and 2009, Yalman filmed the same or similar object on multiple occasions, accumulating footage across many sessions. Other residents of the compound witnessed the sightings alongside him on several nights, and their accounts were consistent with what the camera captured. By the time the full footage was compiled, it ran to approximately two hours in total — an extraordinary volume of continuous video evidence for any single UAP case.
The original footage filmed by Yalcin Yalman at Kumburgaz across multiple nights between 2007 and 2009.
The Kumburgaz footage is remarkable for what it appears to show with a level of clarity rarely seen in UFO video evidence. Shot with a Sony camera fitted with a 200x optical zoom, the footage shows a structured object hovering over or near the water at low altitude. The object is disc or crescent-shaped in most frames, with what appear to be distinct sections including a dome, a lower hull, and — in the most debated sequences — what some analysts describe as a transparent section through which interior detail is visible.
It is this last detail that has made the Kumburgaz case uniquely controversial. In several frames of the 2008 footage, zoomed in to maximum optical magnification, shapes that appear to be figures or occupants seem visible through a section of the craft. This has been dismissed by sceptics as optical artefact, lens flare, or compression artefact from the camera. It has not been dismissed by everyone who has examined the footage technically. The shapes remain present across multiple frames and do not behave like lens aberrations, which typically move with camera motion.
The footage also shows the object performing manoeuvres inconsistent with known aircraft. It appears to hover without propulsion noise. It changes aspect relative to the camera in ways that suggest three-dimensional rotation. In multiple sessions, it appears to submerge into or emerge from the water surface — a characteristic that places the Kumburgaz object in the category of USO (Unidentified Submerged Object) as well as UAP.
The footage was submitted to TÜBİTAK — the Scientific and Technological Research Council of Turkey, the country’s primary government scientific body, equivalent in function to institutions such as the U.S. National Science Foundation. TÜBİTAK is not a fringe organisation. It is a serious, well-funded government agency that conducts and evaluates scientific research across all disciplines.
TÜBİTAK’s analysis concluded that the footage could not be explained as a hoax, as a conventional aircraft, or as a natural phenomenon. Their report stated that the images showed a real, physical object and that the footage had not been digitally manipulated. They were unable to identify what the object was. This is an extraordinary outcome: a government science body with no particular interest in validating UFO claims examining footage and formally concluding it depicted something real and unidentified.
The investigation was also taken up by the Sirius UFO Space Science Research Center in Turkey, led by researcher Haktan Akdogan, who coordinated the wider investigation, compiled witness testimony from the other residents who had seen the object alongside Yalman, and brought the case to international attention. The footage won the award for Best UFO Film at the 2009 Sirius UFO World Congress — a recognition from the international research community that the footage represented a genuinely significant piece of evidence.
Analysis of the Kumburgaz footage and the official Turkish investigation — including the TÜBİTAK findings.
In the sixteen years since the Kumburgaz footage was first released publicly, no credible debunking has been produced. The standard dismissals applied to UFO footage — CGI hoax, known aircraft misidentification, lens artefact, single-witness testimony — each run into specific problems when applied to this case.
A CGI hoax produced by a night watchman in a Turkish coastal town in 2007 and sustained across two years of footage with multiple witnesses on multiple nights is not a plausible explanation. The object was not filmed once in dramatic circumstances and submitted for maximum impact — it was filmed repeatedly, casually, as a recurring phenomenon that Yalman had come to expect. That behavioural pattern is inconsistent with fabrication. The TÜBİTAK examination rules out digital manipulation of the footage itself. The multiple-witness nights rule out single-witness error. And the consistency of the object’s appearance across sessions separated by weeks and months rules out coincidental natural phenomena.
What remains is footage of something real, physical, and unidentified, filmed at a specific location over a sustained period, examined by a government scientific body, and never explained. That is, by any objective standard, a significant UFO case.
The most contested element of the Kumburgaz footage — and the reason it has attracted sustained international attention from researchers including Dr. Roger Leir, who studied the footage closely — is the apparent visibility of occupants in the 2008 sequences. Dr. Leir, a surgeon known in UFO research circles for his investigations into alleged alien implants, examined the zoomed footage frame by frame and described what he saw as distinct biological forms consistent with humanoid or non-human figures visible through a transparent section of the craft.
The occupant question cannot be resolved from the available footage. The zoom level required to see the detail pushes the camera to its optical limits, and at that magnification, compression and interpolation artefacts are real concerns. What can be said is that the shapes are present, they appear across multiple frames, their position within the frame is consistent with interior structure rather than external reflection, and no analyst — including those seeking to debunk the footage — has produced a definitive technical explanation for what they are.

The Kumburgaz case does not exist in isolation. Turkey has a documented history of UAP sightings, and the Marmara Sea region in particular has been the site of multiple reported encounters over several decades. The country’s position at the intersection of Europe and Asia, with a long history of military and civilian aviation over its territory, makes it a location where unusual aerial phenomena are more likely to be observed and reported than in many other regions.
What distinguishes the Kumburgaz case from other Turkish sightings is the systematic nature of the evidence: a single witness returning to the same location, the same object returning across seasons, a formal scientific examination, and an international research community that has studied the footage for over fifteen years without arriving at a conventional explanation. It stands as one of the most carefully documented civilian UAP cases in the world — and one of the few in which a government science body has formally stated that the footage depicts a genuine, unidentified, physical object.
Whether what Yalcin Yalman filmed from the shore at Kumburgaz over those two years was a foreign technology, a natural phenomenon not yet catalogued, or something else entirely remains unknown. What is known is that he filmed something real, that others saw it alongside him, that Turkey’s government scientists examined the evidence and could not explain it, and that in sixteen years of scrutiny, no one else has explained it either.
