I'm confused. Do you mean the Daily Mail?
There are two videos at the link you provided. The first one is interesting because it seems to address Barracuda's point:

Unless I am mistaken it appears to me in that video that the spiral disk is slightly oblique relative to the positon of the camera. It also appears to me that I can discern an arcing trajectory in that first video. But that confuses me. Wouldn't any arc in the trajectory of the rocket distort the spiral?
Sure would be handy to see a computer simulation. That might help me visualize things.

This is especially true if, as the McDowell at the New Scientist article you cited says, the rocket failed at high altitude:
McDowell says the shape suggests the failure occurred well above the atmosphere. If it had occurred at lower altitudes, atmospheric drag would have caused the missile to fall quickly to Earth, creating a downward-pointing corkscrew pattern whose contrails would have been blown "this way and that" by wind, he told New Scientist.
Now where the hell is Penguin when you need him?
