The Science of Catastrophic Implosions: Insights from the Titan Submersible Disaster.

The missing submersible that was transporting five people to view the wreckage of the Titanic imploded in the depths of the sea, according to officials. The U.S. Navy detected "an acoustic anomaly consistent with an implosion" shortly after the sub, called the Titan, lost contact with the surface. Implosions happen when objects are under significant pressure, and in the case of an undersea implosion, "in a fraction of a second, it's gone," said Will Kohnen, chairman of the Marine Technology Society Submarine Committee. The remains of the Titanic are at around 12,500 feet down, meaning that the pressure at that depth would be about 400 times the pressure you would feel at sea level.
