So what do we know?
The aircraft flew to a remote Island, carried out three approaches, then ditched. Island reserve should at least be two hours - which should be more than three approaches, and they should have had variable and fixed reserve on top of that.
The interview with the Airport Manager, who rescued them from the sea stated that they had no idea at what time they ditched, or where they were. He stated that they were found in the water about and hour and a half after the accident, by one of the boat crew managing to catch sight of a life jacket emergency light bobbing about about two kilometres off shore. Only three of the six were wearing life jackets - the two pilots, and the patient were the ones who had to go without.
So - if there isn't a question or two in that lot, I don't know what else people need! You have to at least question how "prepared" this ditching was!
