 After the containers are rolled inside, workers unload the cargo and sort it by destination. This part of Worldport is industrial and loud. It's mostly a massive conveyor belt system. I'm talking multiple floors, layers and layers of conveyor belts, 155 miles of them. And they shuttle packages around fast because with one day shipping, UPS can't waste a minute. Within 15 minutes, the majority of those packages are going to be ready for their outbound load.
