Boeing warned plane owners in 2011 about a broken part that contributed to last year's UPS cargo plane crash that killed 15 people, but at that time the plane manufacturer didn't believe it threatened safety,

LOUISVILLE, Ky. (WDRB) -- More than two months after a UPS cargo plane crashed in Louisville, killing 15 people, cleanup continues at the crash site as families search for closure. For the first time, the media was allowed inside the site, where much of the debris has been cleared but visible reminders of the tragedy remain.

Hundreds of workers have worked since the Nov. 4 crash of UPS Flight 2976 in Louisville to clean the land and get the area back to business as usual.

Some businesses will get more access to Grade Lane starting on Wednesday. The owner of Grade A Auto Parts says he's still working to figure out next steps.

What was supposed to be a routine cargo flight from Louisville, Kentucky, to Honolulu, Hawaii, turned into a tragic story. The video was filmed after the filmer, Sydney, received an emergency alert about a plane crash at the Louisville airport.

Businesses in the area around the UPS Flight 2976 crash site have endured, and continue to face, challenges to resuming normal operations.
