First witness spotted three black disks, called second who spotted one black disk spinning/revolving as it darted in and out of clouds

First witness spotted three black disks, then they ran and called second witness. When they arrived the second witness spotted a single black disk spinning/revolving as it darted in and out of dark clouds, camouflaging with the sky. Second witness filmed, and quality is not the best but snippets of UAP can be seen in bottom right corner of video, 0:16-0:18 seconds in, next to a small break in the clouds. This sighting spanned about 5 minutes before the UAP quickly went behind clouds for final time. The sky then darkened into nightfall not long after.
