Air traffic controllers in Siberia are claiming an unidentified aircraft buzzed their city at an incredibly fast 6000 miles per hour!! And at an altitude of over 64,000 feet above sea level. In the video, you'll see the UFO moving at an incredibly fast rate of speed and it appears to be able to dart and turn unbelievably fast! But the really strange part is that pilots of other aircraft in the area say they could hear the alien craft trying to respond to the control tower in a high pitched cat-like meow voice! ALIEN CATS!!!!
