LOUISVILLE, KY (WMDJ) — Federal investigators say an engine detached from the UPS jet that crashed Tuesday morning in Louisville. The death toll as of this writing is now at 12, including a child. 

According to the National Transportation Safety Board, the Flight Data Recorder and Cockpit Voice Recorder have been recovered. These devices are often called black boxes. They sustained heat damage but remain intact. 

The aircraft, a 1999 McDonnell Douglas MD-11F with registration number N259UP (not the one pictured), was cleared for takeoff on Runway 17-Right when flames were seen coming from the left wing. Inman said airport surveillance video shows the left engine separating from the plane before impact. That engine was later found on airport property.

The plane briefly lifted off the runway before striking several structures outside the airport, leaving a debris field about a half-mile long.

Gov. Andy Beshear confirmed the updated death toll late Wednesday afternoon. The NTSB will lead the investigation with assistance from the FBI and expects to remain in Louisville through next week.
