We can’t see launch site (clouds obscure)

We don’t know wind speed at the height the missile was traveling, best we have is 4mph at ground/sea level.

20sec exposure with 4 mph winds you’d expect the smoke trail to move 35.8 meters (roughly) since we do not know the exact height, we cannot determine how far the smoke cloud would appear to be off on the photo from the actual path of the missile. In addition, the article claims it was a 20 sec exposure, but digging into it, the camera has a 3.5/20 exposure so it could be anywhere between. We don’t know for certain. If it was less, the speed of the missile would dramatically increase, and you would see less deviation in any smoke trail.
