Quickly just coming back to Mr. Benson, you seem to almost suggest that SMS is going to replace regulations. Just walk me through this a bit here. If an accident occurs, the NTSB—let's take fatigue, for example, which you raised—may look backward at an accident and say fatigue was a contributing factor in this one, and it could then suggest regulatory change. Can SMS not look at trends going forward, for example, at an issue like fatigue, and inform necessary change before an accident happens?
Anybody else who'd like to can comment on that?
