Look at this idea for pattern.

I'm thinking you could use the basic idea, but simply replace the log cabins with squares of your focus fabric. Even easier, you could start with a smaller square of a solid and then do borders (as wide as needed) of airplane fabric. I'd probably consider making it reversible with a bright more generic Christmas print on back. Boys can change a lot in a couple of years, replacing their interest in planes with sports, dogs, military or whatever....
