Yeah, pressure differentials are no joke. Look at the Byford Dolhin incident [1]: > Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres (24 in) long created by the jammed interior trunk door. With the escaping air and pressure, it included bisection of his thoracoabdominal cavity, which resulted in expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic spine. These were projected some distance, one section being found 10 metres (30 ft) vertically above the exterior pressure door. > The blood of the three divers left intact inside the chambers likely boiled instantly, stopping their circulation [1] https://en.wikipedia.org/wiki/Byford_Dolphin https://en.wikipedia.org/wiki/Byford_Dolphin
