There are more people who have walked on the surface of the Moon than those who have dived below 800 feet. Pascal Bernabe is one of them. In 1996, still unknown to the public, he accepted to dive 577 feet deep to bring back two robots trapped in a cave. The mission was successful. But Pascal got addicted to ultra-deep diving. Dive after dive, Pascal managed to go deeper and deeper. Ultimately, after years of training, he broke the world record reaching - 1 083 feet. But Pascal was not alone. Since the 1960s, scientists, industries and divers have worked hand in hand to explore man’s ability to reach extreme depths. In this quest for the unknown, the risks are huge: high-pressure nervous syndrome and narcosis can often lead to death. Find out how an ordinary man ended up becoming the deepest diver in the world.
