The pilot later told passengers that the accident was the result of a "catastrophic failure of the engine", reports the Guardian's Jacob Steinberg, who was on board the plane.
"We looked out the window and for the first time saw smoke near the wing. We could smell it. It was like burning rubber - bitter and deeply unpleasant - and it was time to panic," Steinberg writes.
