Flying Saucer UFO Filmed as Thunder Storm Moves In (Video)

A classic, flying saucer UFO was filmed zooming over a hilltop as a storm front passed through an unidentified locale. What is it?

A first look at the unidentified flying object may lead most to dismiss it as a bird.

But if it is a bird, then it's the largest one ever seen (easily as big as the surrounding treetops) is saucer-shaped, has no wings and is as pure white as the driven snow.

The YouTube user who posted the video, SimplisticMind, does not indicate where the video was shot. But it's a high quality image, stabilized with a tripod and very obviously intended to catch the dramatic imagery of a heavy storm moving in over the mountains.

The UFO is also enhanced with several video effects, including an X-Ray filter and replay at half-speed. It doesn't help to identify the object, except to make it even clearer that it is no bird or known aircraft.

So what is it?

Here's the video:
