Triangular craft seen flying over, dimly lit at corners and silentMyself, my wife and my twelve year old daughter were sitting on the house roof looking at the sky on Saturday Nov 2006 at 10:15 in the night. Suddenly my daughter sighted this object. It was exactly at the center of the sky. Moving at constant speed, going in north to south direction. It was triangular in shape. Two points of the triangle were leading and one point was trailing. Only some part at the corners of this object were dimly lit. It made no sound of any kind at all. After 15 to 20 seconds this object disappeared. This must be flying at much lower hieght may be 4 to 5 thousand feet. After the incidence we independantly sketched this object and our observation did match with each other. We inquired with local authorities and some astro physisists but nobody could explain.
