A image like that requires a lot of work.
What you need:
1) An image of the airport
2) An image of each plane - 50 or 60 of them.
For each plane
1) Make a selection of the plane
2) Invert the selection
3) Delete the background
Knowing how to use the selection tools is a must here.
Now place all planes onto the airport image - each plane on its own layer.

Correction: an image of each plane, all with the same light orientation... I assume that the OP's picture was created by putting together pictures of planes taken on the same day, and just zoomed/translated a bit. This would be much harder to do with random images taken off the net.

A bit different though, the varoius instances of the plane haven't been cut out. Since the camera was (more or less) still, after aligning the image it was just a matter of cutting vertical strips, each with an image of the plane in it.
