As we were driving northastbound on rte581 bridge, something made me think to look from the passenger seat (where i was sitting) across the backseat driver side window. when i did i was shocked to see a line of 4-5 steady glowing white lights, in a line as if all part of the same craft that was cigar shaped. i shouted,'omg, a cigar shaped ufo!(i had the phrase fresh in my brain b/c i had been thinking about cigar shaped ufo s all day, on and off. i even bought a pack of cigars that same day, something i hadn't done since 1995!). my friend, who was driving, took a quick look out of her window, which was open, and said,'well, i'm a believer now!' she pulled over to stop the vehicle along the shoulder of the hiway to get a better look. i got out and tried to find the ufo again but i couldn't. neither could my friend. it's as if it just vanished. time of sighting was 9:45pm, approximately; and it lasted about 90 seconds to 2 minutes. the ufo was northwest sky, below any clouds (but it was a cloudless night and the stars were out. the ufo appeared to stay in one spot and made no sound that we were aware of. my friend said the lights seemed square shaped and the silhouette looked black and cigar shaped.
