Harrison Okene survived almost 3 days inside a sunken vessel.
In May of 2013, a most incredible act of survival was performed by a man named Harrison Okene. Harrison and his crew of 12 were towing an oil tanker through choppy waters in Negeria, when suddenly a rogue wave hit their tug boat causing the tow rope to snap and it capsized the boat. Turning it upside down the boat slowly began to sink to the ocean floor.
Harrison Okene was the ship's cook. When the boat began to turn over and sink he found himself in the bathroom being tossed around like a rag doll. He eventually got out of the bathroom and went to the engineer's office where he found himself a small pocket of air, where he survived for almost the next 3 days. Sitting on the ocean floor at a depth of 100 feet (30 meters), with no food, fresh water, wearing only his boxer shorts with a dwindling supply of oxygen it seemed as if his death was imminent. The air pocket he was in was small and had only a limited amount of oxygen. As you breathe the space will fill up with the CO2 as well, that of which you breathe out. Lucky for Okene, the water filtered out the CO2 keeping the levels below lethal. Another factor was the risk of hypothermia, if he were to of stayed submerged in the freezing ocean water, he wouldn't have survived more than a few hours. Yet again a miracle occurred and Okene found a platform with a mattress he could prop himself just out of the water with until he was rescued. To top it all off, Harrison found a bottle of coco-cola to drink. Through amazing luck and a few amazingly odd coincidences Okene lived to tell the story. Here is a video of the moment he was rescued.
