The two pilots who were so engrossed in their "work scheduling" that they lost track of where they were have had their licenses revoked by the FAA. Too bad, so sad. But they have gained so, so much. David Letterman made them the focus of a recent Top 10 list: Top 10 Excuses of Northwest Airlines Pilots. And today's Urban Dictionary word of the day is dedicated to the duo: "Northwest Nap - A very deep sleep where you are unable to hear telephones, text messages and even the Air Force. As in Dude, I was so tired yesterday, I took a Northwest Nap. My girl called me 15 times and I didn't hear a thing." Soon there will be a book deal - a bedtime story perhaps? And then of course, an endorsement for pillows or mattresses.
