New Report of UFO in Montana

A video has appeared YouTube on the 11th June 2012 in Montana. The video seems to be a clip filming the snow covered Mountains. As the camera pans from right to left, an UFO can be seen zipping through shot also from right to left. The video then replays in slow time. you are able to clearly see a shinny oval object move through.

It doesn't look like a bird or a plane. Any ides??
