The full video only lasts about a minute.
The time it took to lay down exposes that it is not an airplane. The news film begins when the contrail is about half the length it is by the end of the video. If it were an airplane it would take a couple of minutes to cover that much sky that far away. (To be an airplane contrail coming from the horizon it would have to be much further away than 35 miles even at the end of the video when it simply disappears from view.) The video shows it all being laid down in a few seconds.
But it remained in sight for ten minutes, according to the camera man. Would a missile launch remain in sight for ten minutes?
