On 18 June 2023. Titan, a submersible submarine operated by American tourism and expeditions company named OceanGate, got imploded during the expedition to view the wreck of the titanic in the north atlantic ocean off the coast of Newfoundland, Canada. Inside the submersible there were Stockton Rush, ceo of oceangate; Paul-Henri Nargeolet, a french deep sea explorer and titanic expert; Hamish Harding, a british billionare businessman; Shahzada Dawood, a pakistani-british billionare businessman and Dawood's son suleman.
Communication was cut off with Titan, lost 1 hour and 45 minutes into it's dive. The Authorities were alerted when it failed to resurface at the scheduled time later that day. After it wen tmissing for 4 days, a remotely operated underwater vehicle discovered debris field containing parts of the Titan, about 500 metres (1,600ft) from the bow of th etitanic. The search area was informed by United States Navy's sonar detection of an acoustic signature consistent with an implosion around that time when communications with submersible ceased, saying that the pressure hull got imploded while Titan was descending, resulting in a instant fast death to 5 people inside the submersible.
The instant collapse of the pressure, the hull would immediately heat the air in the sub to around the surface of the sun's temperature, as a wall of metal and seawater smashed one end of the boat to the other, all in around 30 milliseconds.
