I know the chief "test" pilot for United (he mainly ferries new Airbuses from France to Washington state) flew F4's for the Navy...
On a similar note, do you think we will see more career civilians fill these rolls in the future? The military route is becoming less common and civilian test pilot training is starting to pop up. The reason I ask is because the trend is starting to become evident in tactical law enforcement, due to the emergence of REPUTABLE private training facilities (Blackwater, Kroll, etc.). Instead of taking former military (which there are less and less of, definitely not because it isn't good enough), more civilians are assuming tactical positions.
