When you look at many of the pictures of this "phenomena" you look to the north or in that general direction because there is water to the left so I assume that's the North Sea , that means that the 'White Sea' is down to the right in the picture and the missile seams to come from that direction.
The missile is probably failing in the very beginning of the launch - that is the blue streak of fuel leaking at high speed.
The white Spiral is fuel and probably fumes from fire and the reason for the wider spiral in a flatter shape is because of the rapid deceleration of the missile as the engine stops running, the missile comes almost to a dead-halt but is still rotating violently - hence the white flat spiral instead of the blue elongated spiral !!!!

END OF STORY !!!!
