The United States Coast Guard confirmed on the morning of the 22nd of June that the submarine that went down to visit the wreck of the Titanic imploded due to the high pressure of the depth they were heading, which instantly killed all of the passengers: four tourists who paid for the trip, and one captain, who was also the creator of the vehicle.
The submarine started the immersion on Tuesday morning, June 18th, and lost connection to the land crew just 1 hour and 45 minutes after the descend began. This was not immediately informed to the authorities, but instead, the crew waited till nighttime to alert them. The rescuing efforts involved the United States Coast Guard, the Canadian armed forces, and lots of international cooperation.
During the investigation, a Canadian sonar detected “banging sounds” with a 30 minute interval on Wednesday night, which was initially interpreted as a sign of survivors inside the vessel, but after further investigation, scientists were unable to link the detected sounds to the passengers.
The rescuing efforts were on time trial, as there were only four days of oxygen available for the five passengers to breathe on inside the vessel, which could have been even less due to the multiple factors that could affect the quality of the air inside the vehicle, such as gases produced by the bodily waste and the accelerated consumption of oxygen due to fast breathing in panic attacks.
Sadly, all joint efforts were useless in the end when researchers located debris from the submarine around 400 meters away from the Titanic wreck. The discovery of five major pieces of the submarine indicated an implosion of the circular vessel, which killed all the passengers instantly. The United Stated Coast Guard confirmed that there are now nine vessels involved in the search, though they started a demobilization of the crew as the death of the passengers was confirmed.
