I finally saw something!

Just now, out walking my dog. Arkansas 8:30 CST, moving from south to north. I looked up and saw something moving across the sky very rapidly. Completely silent, no contrail. I could not discern a shape, just a round light. My son at that moment stepped out of his apartment and asked what I was looking at. I asked him, “what is that? Look at that!” He said it was a plane. I said, no blinking lights. He said maybe a jet. I said, do you hear anything? Nope. He said, huh. IDK. Guys, it was moving fast. Really fast. We have planes flying over us all the time. The local AF base fly C-130’s over us all the time. Med flight choppers are around all the time. This thing was 100% silent. There was just something about the way it moved that caught my eye immediately. I can’t believe it! Wow!
