Our Sunday Long Read this week comes from Vanity Fair's Susan Casey, who takes a look at all the human mistakes, errors, disasters and bad choices that led to the end of OceanGate and the tragic underwater deaths of all aboard the Titan submarine.
FATE CLEARED UP the weather, blew off the fog, and calmed the waves, as the submersible and its five passengers dived through the surface waters and fell into another world. They entered the deep ocean's uppermost layer, known as the twilight zone, passing creatures glimmering with bioluminescence, tiny fish with enormous teeth. Then they entered the midnight zone, where larger creatures ghost by like alien moons. Two miles down, they entered the abyssal zone—so named because it's the literal abyss.
Deeper means heavier: pressures of 5,000, then 6,000 pounds per square inch. As it descended, the submersible was gripped in a tightening vise. Maybe they heard a noise then, maybe they heard an alarm.
I hope they watched the abyss with awe through their viewport, because I'd like to think their last sights were magnificent ones.
AS THE WORLD now knows, Stockton Rush touted himself as a maverick, a disrupter, a breaker of rules. So far out on the visionary curve that, for him, safety regulations were mere suggestions, "if you're not breaking things, you're not innovating," he declared at the 2022 GeekWire Summit. "To me, the more stuff you've broken, the more innovative you've been."
In a society that has adopted the ridiculous mantra "move fast and break things," that type of arrogance can get a person far. But in the deep ocean, the price of admission is humility—and it's nonnegotiable. The abyss doesn't care if you went to Princeton, or that your ancestors signed the Declaration of Independence. If you want to go down into her world, she sets the rules.
And her rules are strict, befitting the gravitas of the realm. To descend into the ocean's abyssal zone—the waters from 10,000 to 20,000 feet—is a serious affair, and because of the annihilating pressures, far more challenging than rocketing into space. The subs that dive into this realm (there aren't many) are tested and tested and tested. Every component is checked for flaws in a pressure chamber and checked again—and every step of this process is certified by an independent marine classification society. This assurance of safety is known as "classing" a sub. Deepsea submersibles are constructed of the strongest and most predictable materials, as determined by the laws of physics.
In the abyss, that means passengers typically sit inside a titanium pressure hull, forged into a perfect sphere—the only shape that distributes pressure symmetrically. That means adding crush-resistant syntactic foam around the sphere for buoyancy and protection, to offset the weight of the titanium. That means redundancy upon redundancy, with no single point of failure. It means a safety plan, a rescue plan, an acute situational awareness at all times.
It means respect for the forces in the deep ocean. Which Rush didn't have.
UNFORTUNATELY, June 18, 2023, wasn't the first time I'd heard of Rush, or his company OceanGate, or his monstrosity of a sub. He and the Titan had been a topic of conversation talked about with real fear, on many occasions, by numerous people I met over the course of five years while reporting my book The Underworld: Journeys to the Depths of the Ocean. I heard discussions about the Titan as a tragedy-in-waiting on research ships, during deep-sea expeditions, at marine science conferences. I had my own troubling encounter with OceanGate in 2018 and had been watching it with concern ever since.
Everyone I met in the small, tight-knit world of manned submersibles was aware of the Titan. Everyone watched in disbelief as Rush built a five-person cylindrical pressure hull out of filament-wound carbon fiber, an unpredictable material that is known to fail suddenly and catastrophically under pressure.
It was as though we were watching a horror movie unfold in slow motion, knowing that whatever happened next wouldn't be pretty. But like screaming at the screen, nothing that came out of anyone's mouth made any difference.
Every single choice documented here was inevitably going to lead to death and destruction, and et OceanGate and Stockton Rush --and the people around him -- let it happen anyway. So many failure points were passed were any one of them could have shut the farcical show down for good, but that only happened after the tragic end.
A man thought he was better than the hard science of diving. He thought the rules didn't apply to him. He was wrong, and people died as a result.
It wasn't the first time, it turns out.
