Beverly,
Hello there, I do not really recall who made that comment but it should never have been made simply because the unsinkable ship is a myth anyway, as Andrews put it in cameron's film, "She's made out of iron sir, I assure you she can....and she will"
The thought of someone pronouncing it "unsinkable" and then turns around and sinks it's first time out is kind of eerie is it not? We can attach our own theories to it...religious and otherwise, I believe I commented on this in another message on here further up.
Michael is a very good source of information here as I am sure others are as well, I can also be of assistance to you as my wife could tell you that I drive her crazy with what I know about Titanic.
Sincerly,
Bill
