I don't believe (am almost positive) that this photo has been altered.

I think I see the photoshop. Look at the lower portion of the picture, the foreground dirt is lighter colored with lots of cars, but it suddenly becomes darker as you look further up. The plane background consists entirely of the darker ground with no cars. The line between the dark and light is distinct all the way across the picture.
