Can you see the trail that each light makes?
That represents the movement of the plane relative to the light during the exposure.
Also, the wingtip is pointing downwards, so the plane is turning. That is why there is a curved shape to each light trail.

I was thinking about this shot earlier. I can see the photographers motivation, and it works in theory, but he doesn't pull it off in this case. To accomplish this, you need to focus the camera on the wing/engine, hold it perfectly still and use about a .5 to 1 second exposure. It's clear there was a good amount of camera shake, you can see this on the leading edge. There is blur on the wing and a slight double exposure. This is a great example of how this technique is done right:
Note how the wing is in focus. Since you're traveling the same speed as the rest of the airplane, if you have the focus locked on the wing, the ground lights moving under you would cause the movement effect on a long exposure. A pretty simple concept, but the trick is to hold the camera still. Not an easy thing to do on a low flying airplane, much less one that's turning to land. It doesn't appear this was accomplished in the photo in question. I was scratching my head about how this was accepted, but that's just my humble opinion. The photographer is on the right track though, it's a decent attempt.
