    Another planning failure. To me, this whole misadventure is shocking. It seems like every element of this plan was developed by someone with a poor understanding of decompression theory, or a wish to commit suicide with as much fanfare as possible. I find it difficult to believe, and also find myself doubting (seriously) that this guy had ever made it down and back from 800ft. 500 is a little more believable, but not by very much.

    Well that means at least some info concerning what happened will be openly reported eventually.

    I was contemplating how to do this dive on the cheap with a reasonable possibility of surviving. You don't have to be a genius to figure out you can't pack enough gas. Rebreathers have serious respiratory work constraints at that depth.

    Surface-supplied would be functionally challenging. There isn't enough time for the umbilical to get purged of rich O2 mixes as they are switched at the surface with the a necessarily fast descent. Decompression is doable… pointless but doable. A lightweight hat and umbilical would at least give you communications, live video, hot water, a good chance of surviving HPNS tremors -- and make body recovery easier. :wink:

    Not really sure what the "highest rated level of 65 meters" is about. I know of several of the support staff had lots of dives at 350 FSW and some 400 FSW dives. Please do not take this out of context and say I am saying the support divers had "only" been to 350 FSW. I am only stating that I know the support divers had lots of dives to at least 350 FSW.

    He had done several of his other deep dives in a semi dry suit so I would suppose he was in the same suit for this dive.


    My understanding is the run time was closer to 18 hours. Again, I don't know this as fact just what I have heard.

    A semi dry suit is still a wetsuit and is subject to compression and loss of insulation at depth....and extreme loss of compression and insulation at extreme depths.

    I don't know what the water temperature was for that dive, but I have to think that they thought about exposure protection. I have about a dozen dives below 200', and have never been below 300' yet I think about these sort of things on every dive.

    Don't remember saying it wasn't. And I changed my wording in the above post. I wasn't there and don't know exactly what suit he had so I changed my wording to reflect that.

    I think that info was about his instructor. Was it normoxic only? Or did he ever do hypoxic trimix course?

    Thanks for the info Sterling

    Better than a 3mm, but still not enough (imo), especially when you consider the long decompression, and the effects of cold water on fine motor skills.
