Yeah the napping in the airplane thing has always been a hot item, not to mention illegal per the feds (although I have not found it written anywhere.) Can anyone point us to FAR XXX.XXX or OPS Scec whatever that says sleeping in the cockpit is not allowed and will result in severe disciplinary action up to and including termination and the loss of your license?

However, and not that I would know anything about it, but it seems that a controlled (read, mutually agreed upon with all crewmembers) 20 minute nap at altitude would make for a much safer approach and landing. NASA thinks so, but what do I know I just fly night freight for a living..........
