I cannot think of a single platform today where and NFO would even have rudders. I know the Rhino only has them in the back for trainer configured a/c, pretty sure Prowlers just have foot buttons for the mics (not rudders), and I am reasonably certain that P-3's, E-2's or E-6's don't even sit near the controls. You don't have to be as tall to work in the back.
Exactly, which is why I was thinking NFOs could be shorter than NAs...
