I saw 3 fireball shaped clouds moving almost vertically in the sky. I took out my phone and took a video. Then I stopped the video. A 4th one appeared, but it was different from the other three. I thought for a second maybe that one was a helicopter. Something metallic perhaps on it made it seem to shine momentarily. It didn’t make as much of a trail or move vertically as the others. But then it was gone. Just gone. Meanwhile the other 3 kept making their oddly angled descent. I watched them until they were out of my view.
