On August 26, 1988, a Peruvian submarine "the Pacocha" collided with a Japanese fishing boat
As the crew started escaping via a hatch the leg of a sailor became caught as the hatch closed due to sinking sub's 40 degree angle
Now under water with pressure mounting and water rushing in another crew member began think and pray to Sister Marija Petkovic and suddenly saw a brilliant light
He states that at that moment a supernatural force helped him to lift the hatch open to free the sailor whose leg was caught
This act allowed him to close and seal the hatch saving the lives 22 crewman who were later rescued
Two commissions one comprised of military and one of the Vatican confirmed that it was humanly impossible to close the hatch.
Scientist have determined that it would take the strength of 7 men to open the hatch in those conditions !
