Descending to 10,900 m depth in the Mariana Trench: the feat of the Bathyscaphe Trieste

The bathyscaphe Trieste, designed in Switzerland and built in Italy, is famous for having succeeded in reaching the Challenger Deep, the deepest point of the Earth's seabed located in the Mariana Trench at approximately 10,916 meters below sea level. During this unprecedented dive, the Trieste - piloted by engineers Jacques Piccard and Don Walsh - faced impressive technological challenges, such as managing the incredible underwater pressures that exceed 1,000 atmospheres. But how did this submarine manage to descend so deep? And where is it today? In this new episode of "Impossible Enterprises" we analyze the structure and tell you the story of the Bathyscaphe Trieste, the Italian-built submarine in service with the U.S. Navy.
