What Was the Fate of the OceanGate Submarine? There's Some Wild Speculation.

The crew aboard the OceanGate sub has likely run out of oxygen, given that they reportedly started with 96 hours of breathable air when they ventured underwater on Sunday morning. That is--if they even survived long enough to run out of oxygen. The United States Coast Guard announced Thursday afternoon that a remotely operated vehicle had found a debris field "discovered in the search area"; the Coast Guard is holding a press conference at 3 P.M. to share more. The submersible story is evolving quickly, but in the meantime, speculation about what could have happened is rampant. It's been hard to look away. The pressures at Titanic-wreck depths are crushing--"greater than the bite pressure exerted by some of the strongest jaws in the animal kingdom," as Sophie Bushwick at Scientific American put it.
