A Belgian cave diver spends 24 hours alone inside a pressurized cylinder 200 feet below the Mediterranean - how is that possible?

A man lived 24 hours at 200 feet inside a telephone‑booth cylinder

In this episode we follow Robert Sténuit from flooded Belgian caves to deep‑sea experiments and treasure hunts that trained him for an unprecedented endurance test. We trace the inventions, failures, and decisions that led to a 24‑hour solo occupation of a pressurized tube and ask what that night revealed about human limits and underwater living.

Person: Robert Sténuit
Date: September 7, 1962
Location: Mediterranean Sea, 200 feet / 61 meters deep
Event: 24‑hour occupancy of a pressurized cylinder
Sponsor/Builder: Edwin Link

- At 29 Sténuit entered the cylinder, breathing a helium‑oxygen mix in a steel tube the size of a telephone booth lowered on a cable.
- Sténuit’s background: teenage cave diver in Belgium, trained as a commercial diver with SOGETRAM, and twice failed treasure expeditions that honed his archival and technical skills.
- Edwin Link applied flight‑simulator thinking to the sea, believing time at depth beyond saturation was “free,” and built the device to test that theory.
- During the descent and 24‑hour stay a storm above sank the only boat carrying his air supply, leaving the surface support compromised.
- The experiment’s engineering and Sténuit’s endurance were both tested in total darkness and confinement, with decompression obligations determined solely by depth.
