Out There stories relating to "Germany UFO"

It is possible that atmospheric conditions can make the wings of a plane seem to disappear, but a close look at this video suggests that it may be something else.

This object is unlikely to be a plane because of the uniform glow. It does not function like a balloon. It is not a bird. Also, it's clearly amateur video, so the movement behind the trees is unlikely to be a CGI effect. Therefore, unknown at this time.
