Black Diver myths?
I used to hang out with some people who were commercial divers and they told me about something they called black divers. They would go down under to do their routine work and at some point would notice they had an extra team member. The new diver wouldn’t respond to any communication or stimuli and also wouldn’t expel air from his rebreather. And when looked dead on the mask would just be a void as if no one was inhabiting the suit. At some point the would swim away into the depths or in some cases actively sabotage what they were working on. These phantom divers would done everything from modern diving gear to those old timey saturation suits. Has anyone else heard of this?
