Re: Dead SCUBA Divers
You don't have to be stupid at all when you are diving. Diving below 130 feet is considered technical diving. Both the guys who dove on the U-534 and the ones who dove on the Andrea Doria said that you have to KNOW your gear is good. You cannot help someone on a technical dive, because you risk dying yourself. Each person is on their own, even if they are with their buddy. In recreational diving, you typically carry an extra breathing mouthpiece on your octopus off your air tanks, and if someone signals lack of air, you give them your extra mouthpiece, and then, once things are steady, you return to the surface immediately. I practiced this during my training for my scuba certification. Technical divers don't normally carry an extra mouthpiece. For one thing, on technical dives, you usually have just enough air for the dive. There is NO extra, like there is on recreational scuba dives. If you had an extra mouthpiece and you let someone use it, you would BOTH be out of air and dead before you could surface. If you want to read about how harrowing really deep diving is, read the article "Dave's Not Coming Back". In that particular case, a guy went to 1200 feet depth in a cave in South Africa, with the intent to recover the body of another diver who had died in that cave a year earlier. I think it took him about 15 minutes to make the descent, and he calculated that he had TEN SECONDS once he got down, to put the guy in a body sack and tie him off for hoisting. Unfortunately, he ran out of time, and he died as well. Another experienced diver finally went down and got both the original diver and Dave's body. In that case as well, the bodies had turned into grave wax. The skulls were bare, but everything in a dive suit was preserved. I believe the decompression time after the 10 seconds of bottom time was around 12 hours. There were bottles stashed at multiple levels for use during decompression. I think they went through 13,000 litres of air for that one trip. They were using re-breathers, which supplement only the Oxygen you use, and scrub out the carbon dioxide. If they had used typical scuba tanks without rebreathers, they would have used over 50,000 litres of air for the dive. Recreational scuba is very safe. VERY few people ever die doing that. You are always with a dive buddy, your air supply for use at 130 feet is plentiful, even if you need to share your air. There is normally a dive-master in charge, who checks everyone off the boat and back on afterwards, and the chances of getting stuck are minimal. I got my scuba certifications so I could dive on wrecks, and I am open ocean, deep water, night diving, and wreck penetration certified. I have NO interest in cave diving, nor in really deep wrecks. What these people have done is NOT STUPID, but it IS RISKY. This is an example of where your personal choices can take you. I don't feel sorry for them, they knew what they were doing, and what the risks were. It was their decision, and that leaves their fate solely in their own hands. I do wish there were more pics, so people who are interested in technical diving can understand completely what the results can be. I think both the U-534 and the Andrea Doria wrecks have each claimed 5-6 people in tech diving accidents. |

Re: Dead SCUBA Divers
The first 2 are from Dahab, Blue Hole bottom which is more than 100m The last one is from Tina Watson who was allegedly murdered by drowning during a dive trip https://en.wikipedia.org/wiki/Death_of_Tina_Watson |
