Comment: Nothing enters the picture in the first frame. Impossible.

The plane is traveling over 700 feet per second, and the camera is 1 second intervals. Even if a missile, as you claim, it would not have entered the picture in the first frame.
There is nothing on the far right to see. It is only background, and does not change when the plane enters the picture, to the LEFT of the white contrail (smoke), which is likely engine damage from hitting the light poles.
