This being a very small world we live in....what if we find out the copilot's lifevest straps snagged the Power Levers/Speed Selects/Throttles as he climbed into the cabin as he prepared to jump into the water in an attempt to swim to the remaining survivor who was floundering. The Rescue Swimmer was on the beach administering CPR perhaps.
Well Trained dedicated folks doing very challenging work....my hat is off to them!
