Rare footage from the crash site Titanic will see the light in a few hours, almost four decades after its discovery and 111 years after the crash of the British ocean liner.

The footage was filmed a few months after the discovery of the wreck in 1985 and will be streamed on the Woods Hole Oceanographic Institution (WHOI) YouTube page. According to WHOI, most of the material (only 80 minutes) never saw the light of day.

Many documentaries about the Titanic show footage of the most famous shipwreck in history.

The Titanic was a marvel of shipbuilding for its time. It was characterized as an “unsinkable” ocean liner and was the largest ever built.

On her maiden voyage from Southampton to New York, she collided with an iceberg in the Atlantic Ocean and sank, killing 1,517 of the 2,240 people on board, sparking outrage at the lack of lifeboats.

Researchers from the US Woods Hole Oceanographic Institute (WHOI) and France’s National Oceanographic Institute discovered the wreck on the bottom of the Atlantic on September 1, 1985, southeast of Newfoundland, Canada.

Diving in July 1986 took pictures from cameras on a submarine and a robotic submersible. Today’s discovery of this rare material coincides with the re-release of James Cameron’s Titanic, which premiered at the 1997 Tokyo International Film Festival and won 11 Oscars.
