• 'It's melting the windows': Rare type of engine failure blamed for fire that injured 21

Pilots were forced to abort a takeoff and evacuate passengers from a burning American Airlines flight on a runway at Chicago O'Hare International Airport after the airliner experienced what a federal official said was a rare and serious type of engine failure.

American Airlines Flight 383 to Miami experienced an "uncontained engine failure," in which engine parts break off and are spewed outside the engine, the official said. The official wasn't authorized to speak publicly about the incident and spoke to The Associated Press on condition of anonymity.
