Bright stream of light moved in an s shape up and to the left as a plane entered the same airspaceMy brother called me to say that he has been watching a UFO. He told me where it was located but I couldn’t find it, so he came over. We went in my backyard where there is a huge clearing to look at the sky and UFO through binoculars. The UFO that he was looking at was to the right of the dipper and to the left of the moon. So the star was between the two. I couldn’t tell that it was moving. But what I did notice was a plane that had took off from the airport and was heading in the direction of the supposed UFO. And what was unexpected, we weren’t even looking for it; a big bright light that was located in the dipper took off in an s shape up. My brother said the light looked red/orange. It appeared white to me. It was just a stream of light. The event only lasted seconds. Where ever this UFO was I didn’t see it until it was this bright light in the bottom right of the dipper and went in an s shape up to the left corner of the dipper. I know for sure that this wasn’t an airplane; since I live right by the airport I know the difference. This event took place between 8:14 and 8:20pm.
