It apparently moves like that. The hypothesis of it being a jet contrail means that the movement and direction are optical phenomena, primarily switching horizontal and vertical real and apparent movement..
I'll post a bit from a site with an explanation, then give the link if you wish more.
The idea that its a missile launch comes from three misconceptions. Firstly that the trail is vertical its not, its a horizontal trail, at around 32,000 feet (about six miles). Its the same as this:
This contrail is no more vertical than the road is, and nor are the power lines at 45 degrees. Everything is horizontal its the just the angle you are viewing it from. All of these show horizontal contrails.
Secondly theres the misconception of direction, that its flying away from the viewer, when its actually flying towards the viewer. This is because the base of the contrail seems wider than the tip. Perspective tells the brain that this mean the base is closer. But actually you can see the base has been greatly spread by the wind. Since its still so far away the effects of perspective are greatly diminished, meaning the actual width of the contrail is what is creating the illusion. Imagine is a plane with a 100 mile long spreading contrail were coming towards you; what would it look like? It would look exactly like this.
Thirdly theres the idea that it goes all the way down to the ground...
Sorry, I don’t buy that at all. The picture shows nothing of importance.
Very informative.
Thanks...
