In a small town located in the northwest region of Turkey, one man named Yalcin Yalam would capture an unidentified object on camera on 23 separate occasions. Working as a night guard in the small vacation village of Kumburgaz he would often be outside during the dark morning hours. Near the shore of the Marmara sea he would watch the sky over the course of 3 summers, not just getting fleeting glaces he would often film these objects for several minutes. He would see more that just an object, some even claim to be able to see alien within some of these clips. There would also be multiple eyewitnesses as well as interviews of many of these people making it one of the more well documented UFO cases. 
  His videos were first released to the SIRIUS UFO group run by the researcher Haktan Akdogan. When said to be genuine they would soon be passed to mainstream media making it into the news not just in Turkey but across the world as well. Not long after they would then be sent to multiple official organizations for study, including Turkeys National Council for the Study of Science and Technology. Not one organization was able to find any evidence a hoax or tampering, classifying it as a true unidentified anomalous phenomenon  or UAP. Even today over 15 years later no one has been able to give a good explanation of what caused these sightings.
