I was driving south on the autobahn in Germany in the summer of 1982, somewhere between Stuttgart and Augsburg. Thick forest was on both sides of the autobahn restricting my view to the east and west. It was a sunny, clear day. Suddenly I saw a large, silver cylinder object streaked across the autobahn down the road ahead of me, going east. It seemed to skim the tree tops. There was no sound at all: Nothing like an approaching aircraft, helicopter, etc. This siting happened very quickly because of the incredible speed the UFO crossed the autobahn. I did not see any wings, nose, or windows, and did not think it was an airplane then or now, especially because of the speed and the fact that it was flying so low. I immediately asked my ex-husband if he saw the object, but he was either looking another way or dozing, I cannot rememember. He certainly did not hear anything. It occurred to me the UFO could be a Pershing II missile test launch, but it was far to large and the Pershing IIs in West Germany at that time were black. I did not report this siting to anyone, but I know what I saw and it was very odd.
