UFO Sighting in Munich, Bavaria on 2004-08-20 00:00:00 - 4 lights in a exact vertical formation

A friend and me looking out of the windows, noticing four lights. they looked in best case as airplane warning light from a big radio antenna which stands in the next nearer city.Except they were all white. at the start of our sighting only the third light, counted from above blinked constantly. an hour or so later only the second light, counted from above, blinked constantly. we noticed no further movements or sounds, but the situation really was weird and yes, fascinating.Im absoluteley sure it wasn´t an antenna, cause i lived in the region since childhood and know the further region of many kilometers very well. sadly no photos were made.
