He reported the light and was told to watch on the next pass at which time he saw the light again in the same location. I know this really happened and I have always wondered what the source might have been. My best guess was an unknown Russian probe, but since the fall of the Ex Soviet no such missions have come to light that may explain what was seen. Of course, the ET buffs have their own suggestions. One thing that always bothered me about my Russian probe explanation is the obvious question: For whom was the light flashing?
