The captain who pulls out his iPad to show me his new truck equipped with a vanity license plate that says "FLYBOY." Then proceeds to set the best Econ fuel thrust setting in a CRJ over the Rockies on a day when moderate to severe mountain wave is reported, then goes to sleep. Fun day of correcting negative trend vectors, max powering out of decreasing airspeed, and listening to FLYBOY sawing logs in the left seat.
