Automation makes this hub unique within FedEx. Workers at the other hubs must do much of the package sorting by hand. But at Fort Worth, computers move the conveyor belts, sort the packages and route them. Not that the system is foolproof. Packages fall off conveyors, get misdirected or get wedged in a cranny somewhere.
Workers walk the length of the sorting facility looking for stranded packages.
The first planes pull in at midnight. Because of planes coming from four time zones, arrivals and departures are staggered here. West Coast planes are last in and last out. Planes come in on one main runway. Alliance Airport does have an enlarged parallel taxiway it can use as a second runway, but it's too close for simultaneous landings.
