I have to say, that as far as many see it, Titanic was the be all and end all of all shipwrecks, and probably have similar books to you Colin..........books that I first bought when the wreck was found in 1988?, and have never read again since.
I am of the opinion that it is a grave for many unfortunate people seeking a new life in the USA and should be treated as such, and I just shut off when people start talking about it and going down to see it........it has even cost lives in recent months, because of [what I believe] the morbid fascination to visit it and look at a grave site.
SADLY it wont stop, but I myself would rather look at living breathing ships than a grave many hundreds of feet under the ocean where it should be left in peace with all those that went down with her in 1912.
Just my opinion though.
