Here’s another one. This guy apparently lost buoyancy after surfacing from a wreck dive on Sunday 21st August 2005, at the Kyarra in Dorset, England, and has gone missing since. On 4th August 2005, a female diver failed to resurface from the same wreck.
Waters there are colder than the ones you find in this part of the world. If you are not aware of the dangers involved, you are f***ed. Visibility’s normally worse than the ones in this region.
