Frame by frame, six photos released by federal investigators graphically captured horrifying images of the UPS plane turning into a fireball.

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.

New photos released by the NTSB show the UPS cargo plane’s left engine and the pylon holding it to the wing detached as it took off. The engine then exploded over the fuselage, killing the three pilots and eleven people on the ground.

A quiet Thursday night at Louisville’s busy airfield turned grim when a UPS cargo jet went down just after liftoff, exploding in a flash that rattled nerves across town and sent ripples through the flight industry.
