Yalçın Yalman

Yalcin Yalman is a Turkish night guard who documented a series of UFO sightings near Istanbul between 2007 and 2009.

• Captured extensive video footage using a camera with a powerful zoom lens in Kumburgaz, near Istanbul
• Recorded what appeared to be a structured metallic craft with visible occupants
• Footage reportedly showed a transparent section through which occupants were visible
• Documented sightings occurred consistently around the same time of year across multiple years

• Videos were analyzed by the Sirius UFO Space Sciences Research Center
• Examined by the Turkish Council for Scientific and Industrial Research (TUBITAK)
• Official reports stated the footage could not be explained as CGI or conventional objects
• Analysis found no evidence of hoax, scale models, or special effects

The Kumburgaz videos remain among the most debated and extensively documented UFO footage of the 21st century, with hours of material rather than brief clips.
