It is not impossible that Capt. Smith survived the sinking and lived in cognito to escape ignominy.He may have retired to a monastery to spend the rest of his days in anonymity. If he died in the tragedy, his body had not been recovered/identified which should not have been a problem.Likely he survived and kept an insignificant profile till called by his Maker. Question is, if it was another Captain in command, would Titanic have sunk? We never know.
