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.
The footage was first posted last month but it is unclear when it was taken. A shot of the airport did not appear to show any snow which is normal for eight months a year in Yakutsk, where the temperature last night was minus 36C.
At one point the UFO is showing moving away from Yakutsk at great speed before turning and heading back towards the city.
There was no comment last night from airport officials on the alleged UFO
Some experts claim that it is widely known that UFOs have made contact and landed on earth but details have never been made public.
