I have been preoccupied with the Scott shooting here in the Lowcountry, but I would be remiss in not mentioning that today is the anniversary of the loss of the Thresher (April 10, 1963). 129 crew members and shipyard workers lost their lives on that day. The link recounted what happened on that day 52 years ago. I'd like to think that the improvements that came about due to that tragedy (notably SUBSAFE) keeps submariners today safer and better able to perform their duties.
