The OceanGate Expeditions vessel was set to descend 2.4 miles below sea level to the wreckage of the Titanic in the North Atlantic Ocean on Sunday (June 18), but it lost communication an hour and 45 minutes into its trek. U.S. and Canadian officials spent the subsequent days searching for the missing submersible, which only had a 96-hour supply of oxygen on board in the event of an emergency. The U.S. Coast Guard confirmed on Thursday that they'd discovered pieces of the Titan in a "debris field," meaning that all five passengers died in what appears to have been a "catastrophic implosion" [via NPR].
