Sorry, Lambsie, but I cite the recent Lufthansa Airbus that got airborne with the captain's side-stick cross-wired. The controls 'full and free check' showed nothing awry, and only the quick thinking of the F/O saved the day. It wasn't a control jam, but shows what can happen when the electronics are shafted.
It is a pertinent question that's worth thinking about, especially on the fly-by-wire equipment.... perhaps you disagree.. ?
