Pilot Atilla Senturk, whose phone footage of the object can be viewed in the video below, described it as an "incredibly bright celestial body at high altitude." ... "It was not a satellite or a star. Then it disappeared at an incredible speed. [It] was very close to us and very bright despite the sun." "Cabin supervisor Efsun Selin Sezer and First Officer Ozgur Erdas were [also] witnesses." While the video is difficult to make out, it certainly seems to show something in the sky nearby.
