In one of the news reports reprinted in a post here (sorry, I couldn't find it again...), it states that the survivor said she offered the man her octo and they were sharing air while she tried to deal with his weights, but they both continued to sink. It then says that when she became very low on air, he pushed her away so she could get to the surface on the remaining air.
I put that part above in bold because it really struck me what courage this man had to do this. Would you be brave enough to push away the other diver who had the only air left so that they wouldn't become a victim, too? I'm not sure I would have had the courage in that situation.
And I know that we've all criticised these folks for making newbie mistakes that lead to a tragic accident. But let's take a moment to recognise the bravery of this man. I am amazed!
