The fiery crash of a UPS plane shortly after its left engine flew off its wing and sparked a massive fire during takeoff could spell the end of the airliner involved.

The National Transportation Safety Board released a preliminary report on the deadly crash of a UPS cargo plane that killed 14 people, including three crew members. The report, which was released on Thursday, Nov. 20, included a dramatic sequence of images showing the plane's engine erupting into flames.

Worn connecting hardware likely caused the left engine to detach from a UPS cargo plane that crashed in Louisville, Ky., the NTSB said.

New images from airport security video shows the UPS plane's left engine detach from the wing moments before the deadly crash.
