At first i thought it was falling star with visible light trail. but as it was dropping i realized it was getting closer, and as the prospective changed i could see it was two very faint lights. as it leveled off in a rounded motion the lights became bigger, and as they past over me i could see a faint outline of a rectangle with rounded ends grey in appearance with two offset dim orange lights underneath. it was not an airplane or a helicopter, my only reasonable explanation would be two birds with white bellies flying absolutely silently and without flapping with wings, having light from underneath illuminate them as they flew over. however the street lights here are bright white color temp down facing lights so it would be strange for there to be orange light reflected upon them, as well as this would not explain the light trail as it first descended. the speed of the craft was also very quick for birds to as it seemed to have come down from a very high altitude and passed over head not much more then a couple hundred ft above me in all of 30 or so seconds. it was completely silent and had no extraneous movement (i.E. how a birds body moves while flapping their wings). it came from a north- north east direction and continued on a south- south west direction.
