How much sleep do you think you would get with 6 hours "behind the door?" Here's what I figure for me... best case: I walk into the room and the clock starts running. I know from experience that the absolute fastest I can change clothes, unpack, brush my teeth, take a shower, lay down in bed, and go to sleep is about 30 minutes. Best case. Sometimes it takes me longer. Then, if I really rush in the morning, I can be ready to walk out the door in 30 minutes. I usually allow 45 minutes but can do it in 30. So with 6 hours "behind the door," the most sleep I'm going to get is 5.

Can you do better than that? Do you think 5 hours sleep in a 24 hour period is enough sleep to be well rested and 100% to conduct a flight? How about several nights in a row like that? Do you REALLY think 6 hours "behind the door" is safe?
