Thank you for reminding me of this. Except for reminding me of his method of speaking. I have every reason to believe the veracity and honesty of two of these men. So the "bondage" wings were unable to lift Jane off the bottom, several days after she was lost. She was presumably very negative on the hang (a bad thing), using a lot of lift from the BC to acheive neutral buoyancy. With her wet suit, she would clearly have been more negative on the bottom during her dive. Presumably she managed to achieve at least near neutral buoyancy, as she was able to leave the bottom with no reported problem. Now, in ascending from thirty to twenty feet, she would have needed to dump some air. But at twenty feet, she suddenly lost her neutral buoyancy, going negative,and heading down. So what happened at twenty feet? Did she dump some air, but the dump valve stuck open? Did she fail to dump enough soon enough, and have the overpressure go off and get stuck? What makes her all of a sudden uncorrectably negative at twenty feet, when she was doing fine at thirty and below, with more need for lift. If she was uncontrollably negative at twenty feet, then it does seem reasonable that she could not be made neutral at depth, where wet suit compression and (possible) lungs filling would have added to the lift requirements of the BC further. -- Wrolf Wrolf's Wreck: http://www.concentric.net/~Wrolf P.S.
