A search expedition of a deadly shipwreck off the coast of Nigeria turned into a rescue mission when a diver exploring the sunken vessel found a lone survivor inside an air bubble.
Harrison Okene, the cook aboard the Jascon 4 tug, was discovered when a recovery diver scouting for bodies encountered Okene's hand wriggling frantically underwater. The Nigerian cook managed to stay alive nearly three days inside a pocket of air in the ship.
The rescue took place in May, but a video of the scene was just released, complete with audio of the diver and the voice of an astonished colleague instructing him from the surface. Both of them react excitedly upon seeing Okene alive.
"Just reassure him. Pat him on the shoulder," the guide can be heard telling the diver, who clasps Okene's hand.
"Just reassure him; give him a thumbs up."
Okene's 11 crewmates perished after their boat capsized in May. You can watch Okene's rescue on the embedded player above, or skip to the 5:30 mark to catch the moment when the diver first spots the survivor's hand in the darkness. The video was posted on the controversial video-sharing website LiveLeak, which has in the past come under fire for posting graphic and extremely violent content.
Although Okene's survival might seem like a fluke or miracle, Rachel Nuwer on Slate has a good explanation of the physics of the situation. Apparently the case has caused a lively debate on an online physics forum, with one physicist speculating that the air bubble around Okene must have been connected with another one in a different part of the boat.
