It really does sound that SW screwed up scheduling the cleaning for before sunlight as a solitary dive with a spotter would be difficult to watch safely as the tank was cleaned, perhaps with clouds of dolphin dung? Other possible screw-ups would be complications of that poor scheduling, I think, and they were mean to force resignations.
I draw a different conclusion...
I think the people who resigned screwed up.
Why was Preito's distress not noticed prior to her going unconscious and sinking to the bottom? If those who were responsible for her safety could not see her because it was too dark, they should have grabbed a flashlight!
I'm not really buying into the "too dark theory" and I really believe that the individuals responsible for Preito's safety goofed up.
I don't like to speculate or make "guesses" without FACTS ... BUT ... it might not be unreasonable to guess that Preito's tank valve was in the "off" position based on what the newspaper reported.
IF we make that
ASSUMPTION, then who was the person responsible for checking her gear pack before she enteresd the water? Did Preito turn her air "on" and the person who checked her out turn it "off" because they weren't paying attention? Did they forget to turn her air on before she entered the water? Did they check to see if her LP inflator hose was properly attached to her BC? Did they check her air pressure before she entered the water? Did they check to make certain that the weight system was properly donned so it could be doffed easily if the diver went into distress? Did they put a burst of air in her BC before she entered the water so she wouldn't sink to the bottom accidently? Did they monitor her comfort level when she entered the water?
The fact is,
WE REALLY DON'T KNOW.
None of the forum readers were involved in the investigation and we are only reading "third hand" information from a newspaper. That is NOT a reliable source!
My guess is the folks at Sea World did a thorough investigation and found fault with those resposible for Preito's safety. There is no way in heck I am going to second guess this decision without FACTS but I am certain the Risk Management Team at Sea World has more information to base their decision than we (the forum readers) do.
I will trust their judgement since they know more about this incident than the Orlando Sentinel reporters.
I am still of the opinion though that Yohn (the rescuer) rose to the occassion and did a great job making the rescue and Preito is fortunate to have survived this close call. I believe all involved learned a great deal and they are more likely to pay attention to detail in the future.
