American Experience

S31E02 Sealab

In 1969, just off the California coast, a US Navy crane meticulously lowered an enormous tubular structure into the ocean. This ambitious engineering project was a pressurized underwater habitat, intended for a select group of divers to live and work on the seafloor for extended periods, ranging from days to months. Sealab unveils the lesser-known narrative of this bold initiative that pushed the boundaries of human endurance and transformed the field of underwater exploration.
