cargo plane crash

The NTSB investigation determined that the left engine and wing attachment system separated seconds after takeoff due to severe fatigue cracks in a critical component. The cracks had previously been identified but were not considered a safety hazard, and they spread across 75% of the surface in the pylon's rear attachment bearing, leading to the separation of the engine and pylon from the wing

The vice president of UPS released a statement naming the crew members of the cargo plane that crashed during takeoff at Louisville Airport: "Words can’t express the sorrow we feel. United, we are strong."

Update: at least 12 people died due to the engine separating from the wing during takeoff run, initial NTSB findings say. The black boxes have been removed, with data expected to be recovered
