Driving west on route 60 about to come up on route 33 to get on interstate 295. So about 1 minute away from bottoms bridge route 33 driving west on route 60. I saw a commercial airline to the southwest which was bright because the sun was setting. I kept my eye on it while driving so I could make sure it was a jet. And it disappeared. I pulled over wandering where it went, and it never showed. The only explanation is that I couldn't see the clouds above cause the sun was setting and it flew right behind heavy clouds. If that wasn't the case, it was a ufo.
