The only severe weather we have here in Michigan is that it's really cold again. I never know from one day to the next if it's going to be 50 - 60 degrees, or in the 20s like today. I looked up Worldport and found this on Wikipedia. The place is fricking big. It's YUGE!
Worldport is the worldwide air hub for UPS (United Parcel Service) located at Louisville Muhammad Ali International Airport. Because of UPS, Louisville is the fourth-busiest cargo airport in the world, and the second busiest in the United States. Although UPS has had a hub at Louisville since 1980, the term was not used officially by the company until 2002, after a $1 billion, five-year expansion. Previously, the project was named Hub 2000. The facility is currently the size of 5.2 million square feet (48 ha; 80 football fields) and capable of handling 115 packages per second, or 416,000 per hour. With more than 20,000 employees, UPS is one of the largest employers in both the city of Louisville and Kentucky as a whole. The facility, which serves all of the company's major international and domestic hubs, mainly handles express and international packages and letters.
A 1,000,000-square-foot (93,000 m2) expansion was completed in spring 2006 to integrate heavy freight into the UPS system. The expansion was prefaced by the purchase of Menlo Worldwide Forwarding, formerly Emery Worldwide. The new facility, designated Worldport Freight Facility (HWP), went online in April 2006 and was the first of the company's regional hubs to begin integrating the Menlo volume into the system. Menlo's facility in Dayton, Ohio, was taken offline in June 2006.
In May 2006, UPS announced that for the third time in seven years it would significantly expand its Worldport hub, with a second investment of $1 billion. The second expansion was completed in April 2010, with the facility now measuring 5,200,000 square feet (480,000 m2), with a perimeter of 7.2 miles (11.6 km). The plan was for more than 1,000,000 square feet (93,000 m2) to be added to its existing facility, with another 334,500 square feet (31,080 m2) of space to be renovated with new technology and equipment. Worldport sorting capacity was to expand from 300,000 packages per hour to 416,000 packages per hour. Additionally, several ramps at the Louisville Muhammad Ali International Airport were to be built or altered bringing a total increase of just over 3,000,000 square feet (280,000 m2).
