When I first heard about this expedition, I thought, "Icarus." You know, the story of the man with wax wings who flew too close to the sun. I always assume bravado and incompetence among the people of the moneyed class, unfair or not. So now investigators continue to search the ocean floor for information about how a “catastrophic implosion” killed all five passengers of the Titan, the submersible mini-van that suddenly lost communication with its home base. Via CNN:

A dayslong international search effort concluded Thursday after debris from the submersible – known as the Titan – was found about 1,600 feet from the historic wreckage of the Titanic. Military experts found the debris was consistent with the disastrous loss of the vessel’s pressure chamber, US Coast Guard Rear Adm. John Mauger announced.

[...] As officials work to determine the timeline and circumstances of the accident, remotely operated vehicles will be used to map out the vessel’s debris field, which is more than 2 miles deep in the North Atlantic Ocean, Mauger said.

Officials have yet to conclusively determine whether the devastating implosion occurred at the moment when the submersible stopped communicating about 1 hour and 45 minutes into its dive, Mauger said.
