The last-known sighting of the Titan vessel, with five crew members on board, is captured in a haunting video.
A 22-year-old videographer, Abbi Jackson, was working on the mothership Polar Prince when five prosperous men disappeared 13,000 feet below.

OceanGate divers went under off Newfoundland, Canada, with 96 hours of oxygen remaining, meaning they will run out Thursday.
It lost contact with the mother ship just before 10am local time after descended in the early hours of the morning.
A videographer (@abbijaxxxon) was on hand to capture the state-of-the-art exploratory technology from the safety of the ship.
The young Canadian whipped out her phone and panned over to capture the moment the Titan prepared to descend.
In the background, she showed off the 22-foot OceanGate sub that had traveled to depths never before reached.
She wrote: “Watching a submarine go down to the Titanic.”
There were sounds heard in the area where the divers disappeared, but the US Coast Guard did not elaborate.
Redeploying underwater drones to find the source of the thuds has so far yielded no results.
