Shocking new photos from the deadly Kentucky plane crash reveal the moment the engine of the UPS Boeing erupted into flames during take off.

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

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 109 remaining MD-11 airliners that have been exclusively hauling cargo for more than a decade.
