Digital marketing tycoon Chris Brown originally planned to go on Sunday’s submersible tour of the Titanic wreckage but withdrew due to safety concerns. His friend, Hamish Harding, is among those aboard the missing vessel. …

Brown said safety concerns ultimately led him to pull out of the trip, but he declined to go into detail.

“I’m not really sure that this is the time to be going into that sort of thing,” he added. “I think that the focus right now has to be on trying to rescue these people. It’s not fair on the families and friends to be making speculation about what might’ve happened or how it happened at this point.”

[The more we learn about OceansGate, the more wise Brown seems. Hopefully the crew can still be rescued, and some indication of noises suggests they may they may still be alive. This should be the end of the submersible-tourist industry either way, at least without a lot more attention paid to safety and redundancy. — Ed]
