The crew was more than 2 miles below the ocean surface, which would have generated more than 5,500 pounds per square inch (PSI) of pressure, more than that exerted by the Oklahoma City bombing in 1995.ĭave Corley, a former US nuclear submarine officer, told Sky News that the hull of an imploding sub moves inward at about 1,500mph (2,414km/h), meaning the time to complete collapse is just one-thousandth of a second, or one millisecond.įriction burn from the rush of compressed air, Corley said, would have been momentarily so intense that hydrocarbons and other flammable gasses, like oxygen, would have ignited inside Titan, mid-implosion.Ĭorley also noted that, because the human brain's unconscious response time to external events is about 25 milliseconds, it's unlikely that Titan's passengers suffered or were even fully aware of their impending doom.Īs Aileen Maria Marty, a former Naval officer and professor at Florida International University, told CNN 'Ultimately, among the many ways in which we can pass, that's painless.' In the depths of the deep ocean, the pressure increases to such an extent that only specially-adapted organisms can survive. Just like the air around the can, which remains unchanged, the powerful ocean pressures would have rushed in to fill the vacuum of the new lower pressure inside the submersible, crushing its wealthy occupants in an instant.
It's the same principle that has powered the pumps of steam locomotives since the 19th Century.Ĭreating this change in pressure inside the Coke can, cooling the hot high-pressure steam back to cold water droplets, works as a scale model of the pressure changes that happened during the OceanGate sub's final brutal moments. The high energy of heated water vapor, in other words, exerts a much higher pressure on its surroundings inside the can's steamy air than an equal amount of cool liquid water would. 'Filling the can with steam and then exposing that steam to cold water causes it to condense back into water leaving no gas particles on the inside of the can to exert pressure outward,' Hambley said. A video posted by James Hambley, a YouTuber who goes by the alias Barded Science Guy, shows a similar process happening to a Coke can
