The final verdict on this video from an amateur astronomer is that this is a meteor. Earlier in the video, a professional offers a more accurate opinion: it’s an unknown. It’s height is unusual for a meteor with such a flat trajectory. The reason is that it has had to move through a substantial amount of atmosphere and is still intact. Meteors seen at low altitude far more often have much more vertical trajectories and thus have remained intact because they’ve moved through a smaller volume of air. Also, this simply disappears when it approaches the ground. There is no impact point, and yet the light return doesn’t diminish. It’s an interesting video and a possible unknown.
