Zohan - well said. A crutch for the intellectually weak.
Four pilots on an 11 hr flight, wonder how long the layover is. I've done close to that through the night in winter with only two of us.
As a perverse knock on to this, and I take no joy in saying it, there will be more jobs available in Asiana if the NTSB cites cockpit culture as a factor. With their experience with Guam & KAL they may well have a jaundiced view.
