We have a home on direct waterfront at a point unobstructed in Rowayton ( Norwalk ) CT and have never seen anything like this!Witnessed 3 yellow/white lights that quickly turned into 3 reddish lights in a triangle over Sheffield Island, Norwalk, CT at 8:35 -8:41PM. Lights were in a perfect triangle and were not moving initially. Within a couple of minutes the three lights formed a straight line equidistant from each other. Within a minute or so the lowest light disappeared, then the middle light disappeared, and finally the third and last light disappeared. One light was visible through binoculars for about 15 seconds after all had disappeared to the naked eye.
