I was told to come outside to view something that my friends saw in the sky because I have seen a UFO at one other point this summer. This time it was one light that moved across the sky. The light just suddenly stopped in the middle of the sky and I thought to myself what kind of aircraft can just STOP in the sky and not begin to fall down to earth? Then the light began to move across the sky again and I ran down a block and it was gone!
