So what? The vastly larger “off the street” pool includes all types of engineers, geeks of all types and peeps who have always had a fascination with aviation even if they didn’t go into the military or go to an aviation school.
I don’t see why this is seen as a bad thing by so many on this thread.
I agree. An even temperament, the ability to focus, adequate math abilities, the ability to think in 4D — all those things would be important, but are certainly not exclusive to aviators. Actually, given that the tower isn’t actually flying; it may be that a computer flight simulator “ace” is more qualified than someone with (say) qualifications to fly a Piper Cub.
