The pilots of the South Korean airliner that crashed and killed 179 people switched off the wrong engine, a report has revealed.

Investigators have found that the pilots of the Jeju Air Boeing 737 that crashed in December, killing 179 people on board, seemed to have shut off the wrong engine that was damaged in a bird strike, according to reports.

SEOUL, July 21 (Reuters) - The South Korea-led investigation into Jeju Air's (089590.KS) fatal plane crash in December has "clear evidence" that pilots shut off the less-damaged engine after a bird strike, a source with knowledge of the probe said on Monday.
