https://peertube.dngr.us/videos/watch/e0474b30-b351-480f-8146-3ee1eb4d57d9 Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe, which with her crew of two 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 in the Pacific. On 23 January 1960, Jacques Piccard (son of the boat's designer Auguste Piccard) and US Navy Lieutenant Don Walsh achieved the goal of Project Nekton. Trieste was the first manned vessel to have reached the bottom of the Challenger Deep. This historic documentary 3700 METERS BELOW THE SEA shows the first tests of the bathyscaphe Trieste, made with the help of the Italian Navy in the summer of 1953 near Capri. The first deep dive took inventor Auguste Piccard and his son Jacques to 1080 meters. A few days later, the Trieste reached over 3000 meters off the island of Ponza. Auguste Piccard retired after this record setting dive. Trieste was operated by the French Navy but after several years of operation in the Mediterranean Sea, the Trieste was purchased by the United States Navy in 1958 for $250,000.
