The wreckage of the aircraft Carrier USS Wasp - sunk in 1942 - has been located on the ocean floor. I don't know if there will be an effort to raise it. My opinion would be don't do it for two reasons. One:77 years of sitting on the ocean floor has to have had a negative effort on the structural rigidity of the vessel. Two: that is now the final resting place for those sailors who perished in the sinking. Let them rest in peace.
