Oblong double line of lights seen briefly in southeastern PA on 11/06/2021

On Saturday 11/6/2021 at 10:03 PM EST, I was driving home with my fiancé in Broomall, PA. I saw something in the sky in my upper right field of vision. It was an oblong double-line of lights that was on a slant. My first thought was that it was an airplane crashing because it was low and the angle seemed wrong for an airplane. The lights/object tilted in a fast and very smooth way that seemed off/unusual (it was moving on a tilt rather than flying away). Then it disappeared out of nowhere. I immediately asked my fiancé if he saw that and he said yes. What he described seeing is consistent with what I saw. I thought that it could have been a reflection. I looked at my windshield and could only see the inside of the car reflected (i.e., the car screen showing different icons). I do not think it was a reflection.
