Driving on 287 in Edison NJ, I saw a disk shaped crafter that disappeared after a moment.I was driving on 287 around 3:45-4:00 AM coming home from a Labor Day BBQ/Party. When I looked up in the sky and saw six white lights in a semi-circle, with red lights on the top and the bottom. I was thinking it was a few lights too many for a plane but I didn't think much of it. I looked up again not more then 5-10 seconds later and it was gone. Between the extra lights and speed of which it disappeared made me think that "Hey maybe this isn't a conventional aircraft"
