I was driving home from church with my mom, when I saw two shapes in the sky. They were right next to each other. I could easily tell that one of the shapes was moving and was indeed a plane producing contrails. The other object, however, was not moving. It was at a standstill in the sky. It was a diamond shaped object. We sat at the light for about 4 minutes and the whole time the second object didn't move. With each passing minute, the plane got farther away and I could tell it was by the contrails coming out of the plane. The object didn't move at all, in the few minutes my mom and I sat at the light.
