LOUISVILLE, Ky. — The search for victims of the UPS cargo plane crash continues as investigators seek to uncover the cause of the tragic incident that unfolded near the Louisville Muhammad Ali International Airport. At least 12 people, including a child, have died from the firestorm that engulfs the wreckage of the McDonnell Douglas MD-11, which took off earlier this week before an engine failure occurred. Authorities are now faced with the daunting task of assessing the damage, as the flame from the crash spread and also impacted nearby businesses. Eyewitness accounts describe a scene of panic as flames engulfed the aircraft. A total of three crew members were on board the cargo plane, the status of whom remains unreliable as investigations continue. The National Transportation Safety Board (NTSB) is leading the investigation, which may take more than a year to yield concrete findings on the cause of the fire. The crash bears resemblances to a devastating airline disaster in 1979 involving similar aircraft components, but the exact sequences of events leading to this catastrophe are still under scrutiny.
