Witness Account

We were driving on the highway just south of Pinetop Arizona. It was a beautiful clear night around 10 pm. I noticed a bright light in the sky to my righ. I wrote it off as a star. Suddenly something was right behind me. It was around 30 feet wide at least. It’s main lights were at least 15 feet apart and there were two smaller lights closer together below. After around 10 seconds or so it just vanished.
