A search is underway for a missing submersible that carries people to view the wreckage of the Titanic. Canadian officials say the five-person submersible was reported overdue Sunday night about 435 miles south of St. John's, Newfoundland. The search is being led by the U.S. Coast Guard. The owner of the ship that launched the submersible confirmed that it was operated by OceanGate Expeditions. That company has been operating annual voyages since 2021 to the wreckage of the iconic ocean liner. In a statement, the company said it is working to bring the crew back safely.
It might be best practice to use a vessel rated for considerably deeper than you actually go, in case of some problem in the hull?
And/or it’s just a description of a particular vehicle they’re bringing that was most convenient to get there quickly.
It’s not like they’re going to say, “oh, don’t bring THAT recovery vehicle, it can go TOO deep.”
