While on a routine training flight off the Turkish Aegean coastal town of Candarli, two Turkish air force trainee pilots saw a bright object that approached their plane at high speed and reportedly gyrated around them for about a half hour.

The Turkish newspaper Hurriyet reported this call: "Object approaching the wings. Now it’s behind the plane … now it’s in front of us."

They told their controller and the regional war alert center of the Turkish army that the UFO had an unusual shape that looked like a cross between a cone and a disc.

Turkish air force sources say they are investigating. So are the neighboring Greeks. The Turks are planning to report the encounter to international organizations, including NASA.
