Crew member on sinking Costa Concordia ship reveals simple signal she used to save herself

A cruise ship worker has revealed how she saved herself during the worst maritime shipwreck of the modern era.

Rose Metcalf features on the Netflix documentary Shipwrecked: Nightmare at Sea, which revisits the tragic story of the Costa Concordia disaster, alongside never-before-seen footage and survivor accounts.

The Costa Concordia left the port of Civitavecchia at 19:18 local time on 13 January 2012, with 3,206 passengers and 1,023 crew on board.

Captain Francesco Schettino ordered the ship steered close to the island of Giglio - before disaster struck.

Just over two hours after leaving the port, at 21:45, the Costa Concordia hit a rock, wrecking with over 4,000 people on board. The ship began taking on water, and tilted in the sea.

Tragically, 32 people died during the disaster, including 27 passengers and five crew members. Captain Francesco Schettino abandoned the ship at approximately 23:30 local time.

Along with other crew members, Rose was helping people safely evacuate the ship and on to a lifeboat as it began to tip.

After helping everyone to get across, Rose and four others became stranded due to the ship tilting so high.

Speaking on the Netflix documentary, she emotionally recalled: "It felt like being marooned on a desert island."

"I definitely felt like I'm all alone. Nobody's coming to rescue us."

At that moment, Rose recalled how she began to hear rescue helicopters hovering overhead, however, she said the ship was covering her and others 'like an umbrella'.

"I couldn't get down to the water level, I couldn't get back inside the ship," she recalled.

"At this point we were sinking, and that was the moment when this little reel of my life started playing in front of my eyes."

It was then when Rose's 'fight kicked in'.

She realized she had a flash light in her pocket, and although she 'didn't know morse code,' the dancer began to flash the light to the boat in front of them.

In the documentary, rescue workers can be heard saying: "We have a signal from someone. We're going to assist them."

"All of a sudden, this man floats down like James Bond," Rose recalled.

She and others with her were then pulled up into a helicopter, and were taken to Gresseto Airport, where they were given first aid.

"When I flew away, I could see everything that I loved, and my reality, was gone," she emotionally recalled during the documentary. "But I was alive."

Captain Schettino, who had abandoned the ship, was later arrested and put on trial, and charged with multiple counts of manslaughter and abandoning ship. He is currently serving a 16-year-sentence.

Schettino admitted to making a navigational error, in which he told investigators he had 'ordered the turn too late'.

Shipwrecked: Nightmare at Sea lands on Netflix on 10 July.
