Shining orb flew in a zigzag pattern then disappeared

The UFO we saw was very high in the air, we thought it was a bright star at first. This was a very windy day as Tropical Storm Gamma was passing through, so we are certain this was not a bird or bug - and it was so high in the atmosphere that no creature could survive nor move that fast. The UFO moved lightrning quick in a zigzag from one point to another staying in place for a moment or so at each point of stop, ultimately returning to approximately the original location where we first spotted the it in the dark sky. Then the UFO accelerated up and disappeared out of site, all faster than a blink. We did see a few planes overhead in the sky, I have never seen anything in the sky move like this.
