Hi there...after re-reading the <incident report> concerning Sheck Exley's accident in Zacaton I have a question...especially directly to anyone who is associated with Jim Bowden's "Deep dive project" which may be breaking records as we speak from what I understand...One of the major "mechanical" problems seemed to center on buoyancy...arresting descent by inflating the BC with bottom mix many have compromised gas management guidelines. And Sheck seems to have had a catastrophic problem attaining positive buoyancy at all... Now, I am writing this on-line so forgive me over simplifying, but the tanks holding the bottom mix become useless once maximum depth is attained. Why not side mount the bottom mix and dump the tanks for ascent...or one of them at least. There are many other questions, like what are the tanks made from, steel, composite, and how negative, positive are they filled and exhaused...but the question is, why not dump the extra weight? There may be a simple answer but the only arguements against jetisoning at least part of that extra load that I can work out, do not seem to be strong enough...Task loading is the unknown for most of us I guess since few know what it's like to be at 888 plus feet! Anyhow, if anyone has a thought, please let me know.
