Black boxes from South Korea plane crash failed to record final 4 minutes, officials say

The black boxes of a Boeing jetliner that crashed in South Korea last month stopped recording about four minutes before the accident, South Korean officials said Saturday, possibly complicating investigations into the cause of the disaster that killed 179 people.

After analyzing the devices, the U.S. National Transportation Safety Board concluded that both the flight data and cockpit voice recorders stopped working about four minutes before the crash, the South Korean Transportation Ministry said.
