Synopsis

In 1969, a US Navy crane gently lowered a colossal, tubular structure into the Pacific waters off the California coast. This was an audacious undertaking of engineering: a pressurized underwater habitat intended for a select team of divers to live and work on the ocean floor for days, even months at a time. *Sealab* recounts the little-known story of this daring program, which pushed the boundaries of human endurance and transformed the practice of undersea exploration.
