Inside the FedEx SuperHub in Memphis:

The SuperHub is a world unto itself, with a hospital, a fire station, a meteorology unit, and a private security force; it has branches of U.S. Customs and Homeland Security, plus anti-terror operations no one will talk about. It has 20 electric power generators as backup to keep it running if the power grid goes down.

Every weekday night at the SuperHub, FedEx lands, unloads (in just half an hour, even for a super-jumbo 777), reloads, and flies out 150 to 200 jets. Its aircraft take off and land every 90 seconds. This all happens between 11 p.m. and 4 a.m. Central Time. The SuperHub processes between 1.2 million and 1.6 million packages a night.

From Thanksgiving to Christmas, FedEx will ship 223 million packages worldwide. Last Monday, its busiest night ever, it moved 16 million packages.
