Sixty US sailors emerge from submarine after 60-day submersion study

The video discusses the capabilities of atomic age submarines, which can submerge indefinitely due to their nuclear engines. It highlights an experiment called Operation Hideout, where 23 volunteers lived in a submarine for 60 days to test the effects of prolonged submersion and carbon dioxide levels. The experiment proved successful, showing that long submersion is possible and carbon dioxide can be controlled, thanks to the efforts of these Navy pioneers.
