There were three bright lights in a triangle formation, two in front and one behind them, so they moved and then they formed a perfect line while moving. This event i've watched two times in 2004. I was in M���nster and walking at that time, as I noticed this strange formation, it was so huge that one couldn't miss it. I immediately saw that it was an extraordinary triangle, not a normal formation of planes.I tryed to explain it as a formation of planes, but this formation was so huge and perfect and there were no flashing lights that i rejected this explanation. I was really amazed and excited and watched it until it disappeared like satellites do.
