LOS ANGELES (Reuters) -UPS said on Wednesday it would reopen its sprawling air cargo hub in Louisville, Kentucky, after temporarily shuttering it a day earlier due to a deadly plane crash, a move that will begin easing delays in the delivery firm's global network.

A UPS freighter aircraft destroyed buildings after slamming into an industrial area shortly after takeoff in Louisville, Kentucky, forcing the company to suspend shipping operations from its hub there.

The crash killed nine people and forced a halt to operations at UPS Worldport, a major automated package sorting facility. UPS said that some deliveries could be delayed.
