3 black objects in a vertical line, spinning and changing shape an high altitude.

All 3 objects changed shape, Top object was pyramid shaped. middle was octogon and flat. No sound. Bottom was super 3d and diamond shape. they would spin independently of each other and would move imperfectly in the same direction, getting closer and farther apart. This took place while I was walking my dog on Monday evening. At first it hovered in the same place, each object spinning at different speeds; the line formation was reminiscent of how a clown balances spinning plates. When it started moving, it didn’t seem to move fast but I was on top of a big hill with wide open sky, and it covered a large distance, quickly. And it was increasing in altitude. I also saw a small plane flying past that looked like it was trying to get a closer look at the mysterious objects. I took video and sent to my mom, who lives 20 miles away the next town over. She sent me a video tonight (Friday) of the same craft formation in the sky! With a plane flying by it! We live VERY close to rocketdyne and Santa susana fields laboratory! Home of the worst nuclear disaster in USA history!
