In this video below the person is recording a dark UFO over a factory or changing coal to energy... on a hill. This UFO is unique. Is dark and seems to be as big as the factory itself.
It looks like it has the front pointing to the right and the back pointing to the left. I say that because the back slopes up and the front is long and slopes down.
It looks a lot like the Star Gate Universe craft from the TV show, but I don't see any manipulation in this video.
