David Copperfield, your country needs you...
Interesting how you mention diversions and fakeouts. Saw a TV show on the history channel or somewhere about a group of professional magicians that had been employed by the Allies during WWII to create elaborate methods of making the enemy think that forces were deployed where they were not, and hiding the real forces. They managed to make the enemy air observers think that an important harbor was located miles from where the real harbor was.
In this age of high-resolution satellites and drones, I don't know if this kind of trickery is still possible, but the idea of inflatable planes, fake hangars, and other things occurs to me (in a science-fiction movie they'd use holograms). Hiding a real airfield would probably be a lot harder.
