Audio from the sunken freighter El Faro's "black box" shows the captain ordered his crew to abandon ship about 10 hours after leaving a Florida port and becoming caught in a hurricane last year.

The National Transportation Safety Board said Wednesday it recovered 26 hours of information from the ship's recorder, including bridge audio from the final hours.

The El Faro sank Oct. 1 after losing propulsion in the storm. All 33 aboard died.

The NTSB says the recording starts at 5:37 a.m., about 8 hours after the ship left Jacksonville for Puerto Rico. Capt. Michael Davidson called orders to abandon ship and sounded the alarm about 7:30 a.m. NTSB says the recording ends minutes later.

NTSB didn't release the audio, but is working on a transcript for later release.
