Attempt to spread a little oil on the water....
As I read Don's posts, he surfaced from a dive missing one of a team of three.
He attempted to get help from the bystanders and his remaining buddy, but no one was willing to get involved.
The one thing that I have a serious problem with is that he did not search the surface area properly, which would have resolved the whole problem, but that dosn't seem to bother anybody else.
So at this point having what he considered sufficent air to have time to make a brief search, and faced with no one else willing to help, he made an attempt to find the missing diver. It would be reasonalbe to assume at this point in time that the missing diver was down to less than 10 minutes of air, if we assume that his air consumption was aproximately the same as Don's. Meaning that there was probably a 5 to 10 minute window to find him.
For those who are taking shots at Don, and leaving aside the issue of not searching the surface properly, in the same situation, how would you have handled the situation?
