Two white lights over Kaiserslautern, ramstein area , following each other, no noise heard, suddenly disappearTwo white lights, no blinking or anything. They followed each other on a straight path. The second light seemed a bit brighter than the one ahead of it. we watched the first one come into our view and fly on a straight path across the sky. It all of a sudden started to get smaller and smaller in a fast amount of time until we couldn't see it anymore. The second one did the same just seconds after the first. We knew they were not planes because there were also planes in the sky and we compared it to the planes we saw. We see planes fly over this area all the time.. we have no idea what it was.. but it sure wasn't a plane. Also, I want to add that for something to fly at that level you would hear a noise but we didn't.((NUFORC Note: ISS and Space Shuttle in formation? PD))
