The two people on this planet who have spent the most time exploring and documenting Titanic are National Geographic Explorers at Large James Cameron and Bob Ballard. In an exclusive interview held immediately after news came in that the remains of submersible Titan were found on the seafloor, the legendary deep-sea explorers shared their immediate reactions with National Geographic.
“If you’re an explorer… there’s this idea that there’s a certain level of risk that’s acceptable. I actually don’t believe that,” says Cameron. “I think you can engineer against risk. I think you can minimize the risk down to the few things that you can’t anticipate.”
On Titan and risk
Both explorers agreed that the Titan tragedy was a failure of engineering and regulation. They stressed that the underwater vehicles they use for scientific exploration are products of meticulous testing supported with risk-management backups such as support vehicles that can come to the rescue should anything go wrong.
“I would submit that if you’re going to take passengers into the deep ocean, certainly to the depths of Titanic, you must have another vehicle on board, even if it’s a remotely operated vehicle, to assist in an entanglement,” says Cameron.

Ballard points out the unique dangers of exploring shipwrecks, noting that they pose unexpected hazards such as the possibility of becoming entangled in fishing nets and cables. “Hydrothermal vents? You know what you’re up against. I’m most nervous when I’ve dove on a wreck,” he says.
Cameron agrees. “Shipwrecks are dangerous. There is an element of risk. You can’t stop exploration, but you can’t treat it like it’s just to drive to the office either.”
On regulation
Unlike steel or titanium vessels, OceanGate’s Titan carbon-fiber composite and titanium craft submersible was an engineering outlier. Compounding issues is the fact that OceanGate CEO Stockton Rush chose to forgo the traditional certification expected by the industry.
“It’s okay to move fast and break things as long as the thing you’re breaking is not a submersible,” notes Cameron, “but when you’re at Titanic depth, that doesn’t work out too well.”
(He found the Titanic but for Robert Ballard the search never ends.)
“I’ll stick with titanium personally,” says Ballard. “I’ll stick with the [submersibles] that Jim [Cameron] is building and titanium hulls … after numerous testing with no one in it.”
On robots
The question that sparked a “violent agreement” between the legendary explorers is whether there is still a place for human scientific exploration of extreme ocean depths, or whether we now have the technology to do so without risking human life.
Ballard praised the developments in robotic exploration—in the form of remotely operated vehicles and autonomous underwater vehicles—which offer unlimited exploration time, unbounded by human constraints. “When I went back to Titanic in 2004, I literally was on Titanic for three days,” he notes.
“You’re talking about being on it through the video monitor of a vehicle that’s two and a half miles below you,” Cameron counters. “I still like seeing it with my own eyes.”

“I actually believe the value of a human bearing witness,” the director of the 1997 blockbuster Titanic adds, saying his logic is not technical or scientific, but rather poetic and emotional.
On reflection for future exploration
Both National Geographic Explorers emphasize that the Titan incident is an outlier and does not reflect the careful consideration that scientists build into their research efforts.
“What is the lesson of Titanic?” Cameron asks. “Heed the warnings. Do not let greed and arrogance supersede your best judgment. I mean, the captain of Titanic was highly seasoned, highly respected, and yet he didn’t heed the warnings and he steamed full speed into an ice field on a moonless night. And 1,500 lives were forfeited as a result. That’s the lesson.”
Ballard agrees. “If you don’t study history, you’re doomed to repeat it.”
