    Bob, I think Greg was a Sonarman on Admiral Dewey's Flagship
    USS Intrepid CVS-11 Helicopter Squadron-3 1960-1964

    When I keep my gratitude higher than my expectations I have a good day

    Rickie nailed it. Wiki is a wonderful thing isn't it?
    Hard to believe that sonar has been around for so long yet we think of it as a modern invention... makes me wonder if we are actually discovering anything new at all or just rediscovering it.
    I'll have to think of some more for maybe later - for some reason that popped into my head when I read Rickie's original post and mduncan62 answered it so quickly; I just didn't want the thread to end so soon.
