YOGYAKARTA - The KRI Nanggala-402 submarine is considered to have sailed forever. On April 21, 2021, the KRI Nanggala-402 submarine in Bali waters suddenly lost contact.

KRI Nanggala carried 53 crew members with oxygen reserves which could only last for 72 hours. The TNI then deployed many other KRIs to rescue the 53 crew members.

The conversation on social media is also busy, especially with netizens who wonder why they don't come out of the emergency door and save themselves by swimming to the surface?

There are many things to know about submarines in advance

Submarines do not have emergency doors that can be opened freely. The submarine door is more complicated than it seems to be made to keep water from getting inside.

Their chances of survival also depend on the depth of the water in which the submarines are located. The Nanggala ship was lost in a depth of 700 meters. It means the Burj Khalifa, Dubai, United Arab Emirates.

Obviously, this will be far from a pressure of 3-4 atm. Please note that ordinary humans can only be around 4 atm with a count of 1 atm is 10 meters so that the maximum limit is around 40 meters. With a depth of 700 meters, if it comes out it will be like being trampled by 100 elephants will be crushed due to the pressure of the water.
