Watch as a U.S. Navy ROV Explores the El Faro Wreckage

Federal investigators released photos and video Sunday of the wrecked El Faro, the cargo ship that went down in the Atlantic Ocean during a hurricane last year with 33 people aboard.

The El Faro left Jacksonville, Florida, on Sept. 29, and lost contact as Hurricane Joaquin grew into a category 4 storm. Its wreckage was found Oct. 31 in 15,000 feet of water 36 nautical miles northeast of Crooked Island in the Bahamas.

The National Transportation Safety Board broke six weeks of silence on the investigation Sunday by releasing its accident docket, along with 47 minutes of underwater video and nine photographs.

The docket included no investigative report. In a lawsuit against the ship's owners last year, the family of one of the sailors alleged that the ship "had a history of losing power while under voyage and during hurricanes."

In an interview that aired Sunday on CBS's "60 Minutes," marine engineer Thomas Roth-Roffy, the NTSB's lead investigator on the case, called the inquiry "the most difficult and complex investigation I've ever worked on" in 17 years with the agency.
