Sitting around a backyard campfire, we saw a bright light appear to be lower than an airplane flight path and had a much brighter/white glow. It was moving in a slow, steady straight path then all of a sudden traveled further out into space until the object disappeared into the dark night. All 5 of us saw it happen. At the same time we saw an airplane in the sky and used it to compare the difference between the airplane and the unidentifiable white ball of light.
