Deepest Dive - The Story of the Trieste

Over fifty years ago, two men attempted to reach the deepest part of the ocean, 10,911 metres (35,797 ft) down in the South Pacific. This is the tale of the Trieste vessel and their feat that has never been equalled.

It was a seven-mile voyage to the deepest part of the ocean, and there were only two men in the world right for the job.

Today on Far Future Horizons we join Swiss oceanographer Jacques Piccard and U.S. Navy LT. Don Walsh in this exciting documentary film as they pilot the bathyscaphe Trieste into the abyss of the Pacific's Mariana Trench.

The Trieste was a Swiss-designed, Italian-built deep-diving research bathyscaphe ("deep boat") with a crew of two, which reached a record maximum depth of about 10,911 meters (35,797 ft), in the deepest known part of the Earth's oceans, the Challenger Deep, in the Mariana Trench near Guam, on 23 January 1960, crewed by Jacques Piccard (son of the boat's designer Auguste Piccard) and U.S. Navy Lieutenant Don Walsh achieving the goal of Project Nekton.

The Trieste is currently on display at the U.S. Navy Museum.
