Amid desperate efforts to rescue the five passengers trapped aboard the Titan, a video has circulated illustrating just how deep the Titanic-bound submersible could have sunk.

The unsettling animated clip is currently making waves online.

The immersive 3D demo, created by Spanish animation company MetaBallStudios, depicts a virtual underwater seascape filled with global landmarks like the aftermath of some Atlantis-esque apocalypse.

As the illustrated submersible descends into the digital depths, the video’s perspective passes various global landmarks, including the Statue of Liberty (305 feet), the Eiffel Tower (984 feet) and the Burj Khalifa (2,717 feet).

Other measuring sticks include a Typhoon-class submarine’s test depth (1,312 feet) and the bottom of the Southern Ocean (10,728 feet).

Eventually, the viewer is transported all the way down to the wreckage of the Titanic some 12,000 feet down at the bottom of the Atlantic ocean — where rescuers suspect that the Titan could be trapped after disappearing Sunday.

Aboard the vessel were OceanGate Expeditions’ founder and CEO Stockton Rush, French Titanic expert Paul-Henri Nargeolet, British billionaire Hamish Harding and Pakistani businessman Shahzada Dawood and his 19-year-old son.

With fewer than 24 hours of breathable oxygen left in the sub, rescuers currently racing against the clock to locate the vessel.

On Tuesday, three US Air Force planes delivered critical equipment and tools to Canada — in what was described as the “last chance” to rescue the passengers.

If successful, this would mark the deepest ocean rescue ever.
