Just a couple of points.The Captain stayed on the ship long after the position was hopeless. She was under tow already.
This from Wrecksite.
Flying Enterprise was under tow by the TUG TURMOIL, when she sank in Heavy Weather.
Captain Kert Calson famously stayed aboard the vessel for nearly two weeks with an incredible list to port. The entire world was thrilled with the courage displayed by the brave Captain clinging to his ship in hope that it could have been saved.
After the sinking, it was clear that the ship must have had special cargo, as it was not normal that the US Navy had sent two destroyers in heavy weather to try to protect the ship.
In 1960 a quarter of the ship's $800,000 cargo was salvaged by Sorima but what that actually was I dont think has ever been made public.
I did find an ironing board on the ship and thought it might be Carlson's. More likely somebody " extreme ironing " which some might remember was a silly craze some time ago.
When I learned to dive I could not swim a single stroke and was more than hopeless in the water. Against the rules they kept me on and I took swimming lessons along with the diving lessons. When all seemed lost and I wanted to give up I bought most of the kit.In three years I became an Advanced Diver the first in all of the folk I learned with. Within 5 years I was an Advanced Technical Diver. I also instructed people and learned that all good swimmers do not make good divers.You only fail at something if you never try in the first place.
