Air traffic controllers in Siberia claim to have been buzzed by a high-speed UFO with a female sounding alien speaking to them in an unintelligible cat-like language.
The object had suddenly burst onto flight monitors over the remote Russian diamond capital of Yakutsk, and it was shown flying at a speed of slightly over 6000 mph, and rapidly changing direction.
The UFO was logged at a height of 64, 895 feet above sea level and appeared to interfere with aviation frequencies.
A YouTube footage showed an air traffic controller trying to make contact with the UFO, while a radar showed the UFO moving rapidly through the skies surrounded by planes that were travelling at a much slower pace.
"I kept hearing some female voice, as if a woman was saying mioaw-mioaw all the time," the Daily Mail quoted the air traffic controller as telling the pilot of a passing Aeroflot flight.
The air traffic control monitor automatically designated the UFO as "00000" because it did not have a flight number.
At one point the UFO is shown moving away from Yakutsk at great speed before turning and heading back towards the city.
