For all the supposition I believe the basic sequence that led to this was covered in post #98, with a slight variance. If in fact one tank had "minimal" air consider that at 80' you are at about 3.5ATM. IP let's say 150. So to take a breath about 200 - 225 PSI. Does that sound minimal?
One diver OOA panics and grabs, other diver also in stress and no longer can breath ultimately tries for surface but holds breath resulting in AGE/Barotrauma.
But we will never really know. What we do know is that they were young, did not have a lot of dives overall, and probably could have avoided the issues with more experience.
But finding the agencies at fault is not reasonable, as they really do not do anything but provide an entrance to this sport. Perhaps they should be more adamant about insisting on exhibited basic swimming skills, but until certification is legally required to participate you cannot blame them. So it is a bit of a Catch-22, the more the industry pushes the C-cards the sooner they will find themselves liable overall.
And Thal, I agree with 90% of your position, but you really jump to conclusions here as far as nailing down the number of dives. In and of itself that sounds like someone trying to build a case using specific details that at this point are really unknown and irrelevant. Someone really good in the water can take to diving in 1/10 the number of dives as someone that is a marginal swimmer. The one thing you and I and Bob agree on is that people that don't swim really should not be in the water to begin with, but we have no idea what that particular skill level was with these divers do we?
The following is not directed in any way towards the divers involvled in this incident, rather it is directed at the overall direction this thread has taken:
Instruction is knowledge, not a license. If ANYTHING good can come from this discussion I would hope it would be for those just getting into diving to really understand that before you start diving you need to be a decent swimmer, not great, just comfortable in and under water.
