Investigation underway: A UPS cargo plane crashed shortly after taking off from the Louisville, Kentucky, airport Tuesday, leaving a fiery trail of destruction and a half- mile-long debris field. At least 12 people have died and others are injured, officials say, warning the death toll could climb as the investigation continues.
Black boxes recovered: An NTSB investigation team is on site at the crash location and has recovered the aircraft’s “black boxes” - the cockpit voice recorder and the flight data recorder.

It’s not the first time an engine has fallen off of a DC-10/MD-11.

That particular instance was due to maintenance not following the correct procedure for mounting the engine. It caused cracks in the support pylon and it was just a matter of time. The crazy thing is the pilots did exactly what they should have done. The problem is the warning system for slat disagreement was only powered by the electrical bus supplied by the engine that just departed the aircraft. So the pilots had no idea that the slats on that side of the aircraft retracted due to damage to the hydraulic lines. So that wing complete stalled and 271 people died.
The difference with this crash is the plane was wings level until the tail hit the ground. Also in that video if you look closely the slats are out on the port wing.
