Made for display in a science museum, this looped 16mm film shows a simulated descent in the bathyscaphe Trieste, including footage of its famed dive into the Challenger Deep. While the visuals are not that interesting, the end of the film shows a rare sight — a point-of-view shot of the Trieste dumping some of the thousands of pounds of ballast as it rises to the surface.

Trieste was a Swiss-designed, Italian-built deep-diving research bathyscaphe, which with its crew of two reached a record maximum depth of about 10,911 metres (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.
