3 connected lights were in the sky and vanished before my very eyes.I was driving back from work on a pretty inactive highway. I was texting my girlfriend and I would occasionally look around at the sky then all of a sudden, I looked to my left side and saw 3 lights connected to each other of fairly big size, just sitting still in the sky. I looked at it and said "what is that?" 2 to 3 seconds later, it completely vanished as I was still looking where it was.
