While this improves safety, let's not fool ourselves, what are the critical parts of an airtrip? Takeoffs and landings. What happens if the suicidal pilot act during takeoff or landing? Plus let's not forget AF447 where a mistake by one pilot (involuntarily) stalling the plane wasn't caught by the other pilots until too late.. To be fair this was during an emergency caused by pitot tube 'failure', so there were lots of things to process.
