Hey Keith, that's my "signature" (rewdco), not Roddy's!
A couple of years ago, there was a series on National Geographics channel which was called "The Sea Hunters". It was about shipdiving, very often on WW2 shipwrecks. Amazing what there is still to be found at the bottom of the sea! Anyway, Clive Cussler, together with James Delgado, did most of the research work before the divers jumped into the sea. And Clive always told these words at the end of each episode... How right he was...
Cheers,
Jan
