Unidentified Aerial Phenomenon slowly moving over mountain in Phoenix, Arizona

A slow moving rectangular object has been filmed while flying over the top of a mountain in Phoenix, Arizona on December 1, 2019.


Some people say that the object looks like a typical banner in tow, but normally a banner is attached to and just behind the plane, so we would be able to see a small aircraft and that is not the case when you watch the video, there is no plane.
