I would crop it differently, using something approaching a 4:3 aspect ratio, as I think it suits the image better, and also addresses the issues pointed out by Darren (remember, you can crop anywhere between the limits of 3:2 and 4:3). Here the cropping of the aircraft is completely motivated and will not cause a problem.
I have cropped it as I am suggesting - I hope you see more than the tiny little dot I will see when this is posted
All the best.
P.S. Weird! Before I just edited my comment I cound not see my photo - it was just that dreaded tiny dot that we IE users see in threads these days with photos linked from profiles. But now I have edited the comment I can see the image myself in IE. Now how did that happen (and when are they going to resolve this annoying bug)?
