If the Rex Features photo was shot from skjervoy and the photographer was facing east (edit: /southeast) and those are the sawback mountains in the background (which I think they most certainly are) and I've correctly identified the sawback mountains on google maps then the missile, if it was a missle, must have been fired from roughly somewhere within the cone I've drawn. That squares with the russian missle test from somewhere within the white sea which is where they apparently test their submarine missile systems. Furthermore, and still assuming everything above, the missile had to have been fired in a north easterly direction. The arrow indicates the rough trajectory if it was fired from the white sea.
This at least makes it more understandable why there are no other photos from different angles.
