1983 Former world heavyweight boxing champion Jack Dempsey passed away at the age of 87. He served in the Coast Guard during World War II and achieved the rank of commander.
1988 The first search and rescue agreement with the Soviet Union was signed at a summit in Moscow.

I don’t read all of these. But I have to admire you doing this. I wanted to do something similar but from a wider more general specific. But the amount of work involved was too much. So BZ Chucky!
Fortunately the Coast Guard historian provides the basic text. I add pictures, sometimes additional text and links to additional information.
