Guess it's time to post what I've found out from a friend who was part of the lost dovers' group and on the boat at the time.
First off the dive site is one usually calm with little or no current and used as a checkout site. On this particular day there was apparently pretty rough seas and a lot of current. Maybe they should have dove somewhere else that day. Even a few very healthy, very experienced divers had trouble reboarding the boat after the dive.
Dive briefing cautioned divers to go hand over hand down the mooring line because of the current till reaching the bottom as the current wasn't near as bad on the bottom. Upon entering the water the two divers in question did not use the mooring line as instructed and soon were carried away from the boat, continued their dive and surfaced approximately a mile downstream from the boat. Who's fault would this be?
Also, from what I gather neither had emergency signaling devices or didn't use what they had. Who's fault would this be?
The rest of the news story and rescue efforts are pretty well detailed except that what one of the helicopters spotted was not the woman's pink wesuit but her waving her pink fins.
There are some other disgusting details that I shouldn't even mention, but I can't help it. The boat that "rescued" them was one of thrill seekers. Upon getting to the divers, instead of getting them out of the water and tending to any health issues they were left floating in the water while people flashed away with their cameras. After they were brought aboard, after being in the water for over 7 hours, they were taken inside where the air conditioning was blasting away, and more picture taking was going on. Anybody ever hear of the term hypothermia?
I feel pretty sure some pictures will find their way onto the internet so if you should see any you'll know the whole story of just how much concern there was by the "rescuers" for the divers' well being.
OK, that's enough from me. I'm just relating what was told to me by one of the medical people who were finally taken to the rescue boat to tend to the divers' needs.
