Hmm you don't live lazy, do you?
In no particular order, some thoughts.
A single point of view, because you are going to have your hands full with special effects that even a photoshop wiz would be challenged by. To me that means shadow box.
I'd seriously consider a mirror model. Half the aircraft on a good flat high quality mirror. It really works in that the mind expects everything in a scene like that to be pretty symmetrical, and it's a good way to do it perfectly. It will also solve the aircraft support problem, and turn a 48" x 48" diorama into something manageable.

Not my business but these things look really good.
Make the runway a blur. There's a number of ways to do that, like sliding your art on a copier during the print, or photoshop.
I'd love to see this.
