Triangular shape in sky with bright lights.My wife and I were awoken by a loud siren noise, like a police siren or something. When I went to the window, I heard wind gusts and saw lights. I thought it was a helicopter, so I ran outside to see. When I went outside, I looked up and was surprized to see a large trianglar shape hovering over my house. As soon as I ran outside, the triangle made a loud "bleep" sound and took off, unnaturally fast. And that was it.
