A submersible that takes tourists to the Titanic shipwreck went missing and has about 96 hours of life support onboard (insider.com)

The Titan is the only sub in OceanGate’s fleet that is made to go as deep as the wreck, which sits 12,500 feet at the bottom of the Atlantic Ocean, about 370 miles off the coast of Newfoundland, Canada. The Titan can fit five people — one pilot and four crewmembers — and has 96 hours of life support on board, according to OceanGate’s website.

That is terrifying.
