Hold down the ALT button and go into 'Reference'. Keep holding it
down.  Click on the ghosted out 'Fly' button and you can fly any plane
you wish.
     Another  one  is  to  hold  down  the  right ALT, CTRL, and SHIFT
buttons and go into Reference. Scroll through the fighter planes until
you see the Atomic Moth (oooh). You can fly that!
