The mystery object suddenly burst onto flight monitors over the remote Russian diamond capital of Yakutsk.
It was shown flying at a speed of slightly over 6000 mph, and rapidly changing direction in the early morning sky, it is claimed.
The UFO was logged at a height of 64, 895 feet above sea level and appeared to interfere with aviation frequencies.
On footage posted on You Tube, an air traffic controller made clear he sought to make contact with the UFO.
The Russian aviation workers are heard in the control tower trying to make contact with the ship.
A radar shows the UFO moving rapidly through the skies while surrounding planes in the air travel much slower.
'I kept hearing some female voice, as if a woman was saying mioaw-mioaw all the time,' he told the pilot of a passing Aeroflot flight.
His communication to the Russian plane were disrupted by interference from the UFO, it was claimed.
The air traffic control monitor automatically designated the UFO as '00000' because it did not have a flight number.
