"The Titan is the only sub in #OceanGate's fleet that is made to go as deep as the wreck, which sits 12,500 feet at the bottom of the #AtlanticOcean, about 370 miles off the coast of #Newfoundland, #Canada. The Titan can fit five people — one pilot and four crewmembers — and has 96 hours of life support on board, according to OceanGate's website."

A submersible taking tourists to Titanic wreck has gone missing

OceanGate Expeditions previously told Insider that its sub was designed with help from NASA. Now it's gone missing on a journey to the Titanic wreck.

Insider

"#US and Canadian aircraft are searching the area, as well as large ships, but the hunt was 'complex' because crews do not know if the vessel has surfaced, meaning they must scour both the surface and the ocean depths, said Rear Admiral John Mauger, first district commander of the #USCoastGuard, overseeing the search-and-rescue operation."

Missing Titanic submersible: what is the Titan tourist sub and what might have happened to it?

The five-person craft has 96 hours of oxygen on board and can dive to depths of 4km to explore wreckage of the Titanic

The Guardian

"A number of potential errors could have occurred. One possibility is that the #Titan's communication equipment may have failed, meaning they are unable to communicate with above-water crew but able to freely navigate. It's also possible there is a problem with the ballast system, which controls the vessel's descent and ascent. Another scenario is that the Titan became "hung up on a piece of wreckage that could keep it from being able to return to the surface." #Titanic

@Norobiik Why is it whenever something bad happens, we find out this sort of thing afterward?

Sounds like the Deepwater Horizon, where they skipped testing the cement sealing the well.

And like the Max8 where they skipped training the pilots on the new feature they added.

And like that ship, back in the early 20th century, where they skipped the double hull and the additional lifeboats originally planned. What was that ship called again?

Oh yeah. The Titanic. We haven't learned a thing.

@mike805 No we haven't learned a thing. Deep space & the ocean depths are two of the most unforgiving environments and fastest punisher of mistakes there is.

As one poster said, the techbro mantra of "Move fast and break things" becomes "Move fast, break things then drown" in those places where tolerance for any bullshit is zero.

This whole operation sounds like a clown show. The "one button" thing is NOT reassuring. I'd like at least three, please. Main power, backup power, and emergency ballast release.

The Russian submersibles used, carried by their research ship Academik K..., had the ability to detach the main battery if it failed, causing the sub to surface rapidly.

In one of those Titanic dives, a drone minisub's battery failed and they had a hairy time recovering it.

Arthur Loibl, 60, dove the 12,500 feet to the Atlantic ocean wreck site in August 2021, and says he was 'incredibly lucky' to survive, saying the Titanic expedition was his most 'extreme' adventure.
