The american producer is the third man to reach it, the deepest in the world, 11 kilometers deep (10,898 m).
He is the first one to do it alone.
The two first men to do it were the Lieutnant Don Walsh, US Marine, and the oceanographer Jacques Piccard (from Switzerland), who spent 20 minutes in this place on board the bathyscaphe Trieste on January the 23rd, 1960.
