Turkish Airlines pilots have said an unidentified object with green lights passed over their plane late on May 19, stirring speculation about a possible “UFO sighting.” <br /> <br />“An unidentified object with green lights passed 2 to 3,000 feet above us. Then it disappeared all of a sudden. We are guessing that it was a UFO,” the two pilots told the Air Traffic Control Center at Istanbul’s Atatürk Airport. <br /> <br />The “UFO” was seen around Istanbul’s Silivri district, during a flight from the western Turkish resort town of Bodrum to Istanbul. <br /> <br />The unidentified object was spotted when the plane was flying at around 17,000 feet at around 11:30 p.m. on May 19, according to the pilots. <br /> <br />The plane landed at Atatürk Airport around 30 minutes later. <br />The General Directorate of State Airports Authority said it did not spot any image in its radars similar to what the pilots had described.
