Officials say the black boxes of a Boeing jetliner that crashed in South Korea last month stopped recording about four minutes before the accident.

FileThe two back boxes on the Jeju passenger jet that crashed last month in South Korea stopped recording four minutes before the accident. That's according to a statement released on Saturday by the country’s Ministry of Transport,

The voice and data recorders pulled from the wreckage of the Jeju Air Co. jet in South Korea failed to capture the final moments before the Boeing Co. 737-800 made an emergency landing and crashed, depriving investigators of evidence to help understand the cause of the country’s deadliest aviation accident.
