NTSB. The NTSB said the recovery of the ‘black box’, which recorded navigational data and communications between crew members, could provide “greater insight into the incredible challenges that the El Faro crew faced.” NTSB investigators assessed the condition of the device at sea and sent the recorder to a laboratory, where specialists will review the recording. Investigators hope that the ‘black box’ will help to explain why the El Faro sank, claiming the lives of its 33 crew members. Credit: YouTube/NTSBgov">
