"Swiss engineer Jacques Piccard and Navy oceanographer Don Walsh descended to the bottom of the Mariana Trench, seven miles below the sea's surface. It's the lowest point on Earth, and deeper than any human had gone before - or since.
Above is a new video chronicling the explorers' journey, weaving animation with audio from an interview granted by Piccard in 2005, three years before his death. The interview was conducted by New York writer Victor Ozols, but went unpublished and eventually ended up on his blog. There it was found by German design student Roman Wolter, who made the film."

"Icy cold, pitch black and with crushing pressures - the deepest part of the ocean is one of the most hostile places on the planet. Only two explorers have made the epic journey there: 11km (seven miles) down to the bottom of the Pacific Ocean's Mariana Trench. As a new wave of explorers is gearing up to repeat this remarkable dive, take a look at the mysterious world that they will be plunging into."
