Silver - - SS Gairsoppa.
My instantaneous and intuitive reaction to this major news story was that the sailing and subsequent sinking of this merchant vessel during World War Two [WW2], with that large quantity of silver being carried, was in some manner related to the MANHATTAN PROJECT. Known as TUBE ALLOYS in England at the time. Silver an integral part of the process to separate the weapons grade fissionable uranium-235 necessary to built the URANIUM BOMB [the gun type device as dropped at Hiroshima.].
"Shipwreck of SS Gairsoppa reveals £150m silver haul"
"A shipwreck containing 200 tonnes of silver worth about £150m has been found in the Atlantic - the largest haul of precious metal ever discovered at sea."
"The SS Gairsoppa, a UK cargo ship sunk by a German U-boat in 1941, was found by US exploration firm Odyssey Marine."
"The vessel was on its way back to Britain from India when it ran low on fuel in stormy weather, and tried to divert to Galway harbour, but it was spotted and sunk by the German submarine."
It seems on this particular occasion that my instantaneous intuition has failed me. The ship was bound from India to England and not from England to the U.S., the cargo more general in nature and not strictly that mass of silver!
"On her final voyage from Calcutta, India she was loaded with nearly 7,000 tonnes of cargo - including pig iron, silver, and tea"
The Gairsoppa located at a depth of 5,000 meters [15,000 feet] BUT recovery and salvage of the silver, worth about $200 million U.S. "do-able"! Truly amazing.
