That is one of the more bizarre things I have seen this week. Although I too would doubt that data corruption was to blame as the rest of the image is fine and as you said this was the only one on the card that is hosed up. In my limited experience an image that was corrupted on a CF card would be generally unusable and would not open for viewing. But I could be wrong.
Give me a mile of road and I can take you a mile. Give me a mile of runway and I can show you the world.

I have had worse with my old D30. It took a shot which looked like a half wound on piece of film, and then exposed that half again. (not sure if I'm making sense)
The colours were all screwed up, and the image was a shocker. It was lucky that the image was nothing special. The shots were taken with the same Flashcard, so I might get the card checked out.
Anyone come across any other screwy digital problems like this?

To my mind, the problem is too localised to be CF related. Remember, its not a picture stored on the card, but a mathematical representation - messing with the numbers is very unlikely to have such a limited and smooth effect.

I must agree that I do not think this is a CF problem. The only time I have seen a problem very similar to this was with a film camera.
What I believe caused it was a very tiny water droplet on the front of the lens which in essence acts like a small lens itself. This lens on lens action caused a localized distortion. I have seen this on slide film when I have been shooting in the rain and had water drops on the lens. A lot of this is also dependant upon aperature in use as well. Its a combination of droplet and aperature.
Note that even if it wasn't raining, a single droplet of condensation can form or drop. It looks like a grey overcast day.

Dripstick...sorry..I must be a little slow today. I don't get it.
On the matter of vortex/vortices in pics, I think we are getting somewhere.
I like the rain drop reason, but it doesn't make sense. It was a cloudy day, and it may have contributed to the problem, but how can you account for this shot.
It clearly shows that there is a distortion coming off of both wing tips. The only difference is that when it intersects metal, there is not much (if any) distortion. I think it is actually happening near the aircraft, and the camera captures the moment.
So, it looks like the answer was right under my nose!!!
