The Kumburgaz UFOs (2007)
Between 2007 and 2009, Yalçın Yalman, a night security guard on the Kumburgaz coast along Turkey's Sea of Marmara, filmed more than twenty-five times, using a camera fitted with powerful optical zoom, metallic, shape-shifting objects floating above the water at sunrise. This footage is considered among the most detailed UFO video ever recorded.
Witnesses
1 night guard, several local residents
Why it endures
An exceptional volume of extremely high optical-resolution footage, analyzed by several Turkish institutions, including the national council for scientific and technological research.
Official version (contested)
Turkish authorities confirmed the technical authenticity of the recordings without identifying their nature; skeptics point to insects or reflections filmed in close-up.
