Footage shows the moment passengers on board the doomed Titan sub caught a glimpse of the Titanic wreck for the first time.
The video filmed on a previous descent to the famous wreckage shows passengers reduced to tears by what they saw.
The Titan sub, built and operated by company OceanGate, shot to fame last month after it imploded deep beneath the ocean killing all five passengers on board.
Footage from inside the submersible was filmed as part of a 2022 BBC documentary.
It shows the descent into the pitch black darkness 2.4miles beneath the waves to where the Titanic wreckage has sat since its sinking in 1912.
In the video, the passengers can be seen reacting in awe as they come across scattered debris such as a brightly coloured tile.
In the documentary Reneta Rojas, a Mexican passenger on the vessel can be heard complaining that she couldn't "see any wreckage anywhere."
Ms Rojas was joined by Oisin Fanning, Jaden Pan and pilot Scott Griffith.
Then the pilot can be heard saying: "I see the wreck on sonar," and the anticipation builds.
The crew falls silent, leaving the only noise Mr Griffith updating them on the approaching wreck.
"I don't see it yet, it might be on the right," Ms Rojas mutters.

The bow is now faintly visible through the darkness and Rojas says excitedly: "We are at the bow, please send that message. Oh my god you did it."
"I can't believe it in real-life when you see it. It's so enormous," Mr Fanning says as tears well up in his eyes.
Ms Rojas says: "I'm just crying. We've made it. Finally made it."
The company, founded in 2009, offered tourists the opportunity to travel on submersibles into the ocean's depths for a close-up look at shipwrecks and underwater canyons.
Just last week, OceanGate's website still included pages advertising trips to the Titanic which included information about what to expect from the expedition.
The dream came crashing down when the sub imploded killing all those onboard.
Those killed were pursuing the same dream as those seen in the footage - the awe of seeing this sunken piece of history.
Officials announced that the submersible suffered a “catastrophic implosion” last month (June 28) after a piece of the vessel was discovered near the bow of the Titanic. The wreckage was then recovered from the ocean floor.
A former employee of OceanGate previously raised serious safety concerns regarding the company's Titanic submersible and highlighted the potential deadly consequences.
The employee, David Lochridge, served as the director of marine operations at OceanGate from 2015 to 2018. During his inspections, David discovered numerous issues that posed significant safety risks. However, his attempts to address these concerns were allegedly met with hostility and denial of access to crucial documents.
David's claims are detailed in a lawsuit he filed in 2018 after his termination from the company.
“I don’t want to be seen as a Tattle tale but I’m so worried he kills himself and others in the quest to boost his ego,” David wrote in an email to expedition leader and dive master Rob McCallum.
