Police officer David Martin: "I happened to look over and saw this large, floating object that was just moving very slowly. It was probably about a football field in length. It had three large bright lights lighting up the sky underneath it. I honestly don't know what it was that I saw, other than I know it wasn't a plane or a helicopter or a blimp."
Humans love a puzzle.
We have to know. That's all there is to it.
