Turkish officials are understandably concerned after several pilots received collision warnings brought about by perilously close UFOs picked up on radar. The worrisome situation, reportedly unfolding over the last few days, began on Sunday when multiple aircraft flying near Istanbul's Sabiha Gokcen Airport contacted air traffic control about the troubling automated message. In one instance, a pilot approaching the location received a rather remarkable response when he reported the odd alert. "Sir, we have been dealing with this for the past two and a half hours," the seemingly exasperated ATC operator replied, "several flights before you also received this warning."

Although the nature of the radar disturbance is hard to discern, the pilot indicated that "we see descending traffic 500 feet below us. It appears as an unidentified traffic on our system." Weirdly, the witness subsequently observed that the object "is now five miles ahead of us," before noting that "we also received this warning on our previous flight." The series of warnings sparked a significant search of the nearby air, land, and sea, but nothing that could account for the aerial interloper could be found.

The case is curiously similar to a strange incident that also occurred in Turkey last week. That mysterious matter involved a UFO that was spotted on radar and then vanished over a forest. As with the unknown objects detected near Sabiha Gokcen Airport, a sizeable search for the source of the peculiar ping came up short. While it has been suggested that the various anomalies could have merely been drones, the continued presence of the unidentified craft clearly vexes Turkish officials who undoubtedly hope to put a stop to the incursions or at least figure out what is behind them.
