EGYPT: Second Egyptair Ms804 Black Box Recovered

Egyptian authorities said the "most important" part of the second black box had been recovered. Authorities have yet to discover the reason behind the crash that killed 66 people.

An Egypt-led investigative committee on Friday said a search team recovered the second flight data recorder from EgyptAir flight MS804.

The black box was "retrieved in several pieces," the investigators noted in a statement released a day after the aircraft's cockpit recorder was retrieved, and two days after the wreckage was located.

A specialized underwater search vessel operated by Mauritius-based Deep Sea Search collected a fragment of the box containing the memory unit, considered the "most important" part of the device, the committee added.

The Airbus A320 disappeared from radar on May 19 shortly after entering Egyptian airspace.

An international search team later found debris from the aircraft, prompting authorities to conclude the plane crashed, killing all 66 people on board - 56 passengers, seven crew members and three security personnel.
