Three bright white or yellow lights observed as we turned a corner. i was only passanger with one driver (2 witnesses). i (passenger) observed the lights and after sufficient time to realize it was not a plane and hair to stand up on the back of my neck i quickly told the driver. he saw it also and we proceeded to pull over to observe its flight path at 100-200 feet or just above tree tops as it flew aprox. half a mile over a golf course. it then disappeared in the distance. the most important thing is that we both saw solid stucture or craft connecting the three lights which reflected the surface of the craft around where light emitted. pictures were immediatly drawn and the driver and i created identical images of the craft. it was triangle with three lights on the underside as it flew or possibly towards the back. clouds were also illuminated by the lights so it was apparent it was a craft. no red or green lights present and it was larger than a helicopter. probably between 50 to a couple hundred feet in length. attached are three sketches depicting, in chronological order, the observations i made and drew that evening. i saw three lights out of the front windshield in the first sketch. the second is a view as it flew away over the tree tops on its constant path towards city of rochester. the last is a depiction of where the three lights were situated and how they illuminated the craft.
