The Sound of a UFO | Mysterious Universe: "Sightings of UFOs in the skies of our planet have been reported for decades – and perhaps, even, for hundreds, and maybe thousands, of years. But what about the sound of a UFO? Interestingly, there are numerous accounts on-record where UFOs have reportedly emitted deep, resonating, humming noises that seem to exert some form of both physical and mental influence over the witnesses. Not only that, such encounters have also left eyewitnesses feeling distinctly ill and disorientated."
