Thanks Eno, that was very quick!

So how did he get those edges...

My guess is that he first selected and copied the phantom and then pasted it on another layer. After that he probably pasted the plane again to get the second phantom in the pic (the lower one). Then he probably added some gaussian blur to the original pic.
You can create this effect (just the soft edge, not the blurred background) by selecting the plane and copying it to a new layer. Then, again, copy it to yet another layer. Now you have 2 layers that are exactly the same, both containing the aircraft you selected. Now apply some gaussian blur to the lower layer.
I'm assuming you have adobe photoshop...
Hope this helped.
