He went down 300 FEET on a routine deep-sea job. Then his air-supply cord snapped. What happened next should have been impossible… What if I told you that a man working on the seabed of the North Sea—300 feet below the surface—lost his only lifeline and was left alone in total darkness with just minutes of oxygen? What if I told you that everyone above believed he was already dead? In September 2012, Chris Lemons, a 32-year-old saturation diver, left home for what was supposed to be a routine offshore job. Before leaving, he reassured his fiancée the way he always did. “Don’t worry,” he said. “It’s a carefully controlled environment.” They were planning a wedding. Finishing their dream house overlooking the sea. Talking about children and the life they were about to begin. That night, Lemons descended from a diving bell into the freezing black water of the North Sea to repair underwater oil pipelines. He was connected to the ship by a thick umbilical cord—his air, heat, power, communications, and lifeline, all in one. Above him, the sea was rough but manageable. Below him, everything was calm. Routine. Normal. Until it wasn’t. An equipment failure caused the ship to drift. The cord snagged. Steel began to bend. And then—without warning—the umbilical snapped. In an instant, Lemons lost his air supply, his lights, his communications, and his heat. He was thrown backward into total darkness, sinking slowly to the seabed. He had about eight minutes of oxygen. No one could hear him. No one could see him. And the ship was drifting farther away. As the minutes passed, Lemons tried to find his way blindly through the black water, knowing that if he failed, no rescue would come in time. What happened next defied everything divers and doctors thought was possible. Continued in the first comment below 👇👇

300 Feet Down: The Diver Who Lost His Lifeline—and Somehow Survived
In September 2012, Chris Lemons left home for what was supposed to be a routine job in the North Sea.
Leaving was always the hardest part. Lemons was a deep-sea saturation diver, a profession that kept him away for weeks at a time.
This job would take him more than 120 miles off the coast of northeast Scotland, to the seabed where oil and gas pipelines needed repair. As he prepared to go, he reassured his fiancée, Morag Martin, the way he always did.
