My first reaction on this was that military aircraft, at least front-line
combat types, obviously need a way to override such restrictions in crises,
but civilian aircraft shouldn't. Then I remembered the case of the 727 that
rolled out of control into a dive a few years ago. The crew finally managed
to reduce speed enough to regain control by dropping the landing gear. The
plane was at transonic speed at the time -- there was some speculation, later
disproven, that it might actually have gone slightly supersonic -- and was
undoubtedly far above the official red-line maximum airspeed for the
landing gear. It would seem that even airliners might need overrides.
