Funny thing is, most UFO sighters (sighters?), are pretty specific when they say that no noise came from the craft and it was completely silent.

I like the Travis Walton case though.

These are the first "unexplained" videos that have disturbed me, really creep me out with a sense of foreboding & I can't put my finger on why. One thing I can identify as being "creepy", for lack of a better word, is that in so many of these videos the sky is clear, not a cloud to be seen yet there's that sound.

Thanks every one for the great responses. And those videos were pretty neat to see. Ill be more aware and knowledgeable now if I get to ever experience what some of these people get to experience.
