Southern sky, heavy clouds. First one appeared to be a hang-glider, but too high never descended. A silver-gray Stealth fighter jet shape, but fluid. One "cloud" looked like a huge flock of birds, a spotty "wall". It slightly brightened a large area of cloud before going out of sight behind the clouds. Then something circular and black, but cloudy, then streamed away rapidly, leaving a black "jet" stream, not linear. Two, small, black smoke-like "clouds" streamed down, then ascended back into the clouds. All of this was difficult to visualize with the heavy clouds. I have NEVER witnessed anything like this and I grew up in the midwest.
