Pretty sure there is all sort's of data on under the mud damage using sonar but I don't have that info to hand so think we can leave that as a discussion for further on.

To my recollection they did not run the test on modern steel, I remember they employed an english firm to remake steel to the exact specification's of the original ship. Then put it in a sort of clamp and tested it, it perished well under the estimate that would rule such an idea out, so basically the outcome of the documentary was that the rivet's did have a major role in how the ship sank, if not the biggest, still there must have been all sort's of gashes from the berg to aid the sinking process. The metal sample used was then compaired to the real titanic steel (sample taken from the big piece) and both suffered the same sort of problems with the small crack's formed by the slag mixture. Although they did not test for the difference in today's steel, I am fairly sure there was a mention that today's steel is at the very least 30% stronger. Plus the fact today our ship's (modern ones from like the 80s onwards) are double if not triple hulled so it's a bit unfair to compare the two in that respect. So therefor I would agree somewhat to you'r statement,

'I still seem to think it is somewhat irrelovent to an extent'

The experiment was a bit more scientific as you can read from up there than hittin a chunk of iron with a hammr lol!

The documentary also went into great detail about who was to blame for the sinking, I bet hardly any of you would point the fingure at the calafornian's operator, when infact it was he who did not encode the message properly (as in saying it is an urgent important message) so the Titanic operator's were justified to an extent in not bothering, they had work to do. Still you cant blame him, he was only trying to do his job, but you see, smll error like that contributed to the sinking.

So much fuss is also made about how the lookout's did not have binocular's so they could not see. Irrelvant, back then spotter's used there eyes and only used the binocular's to confirm a sighting, so if anything having them would of slowed the message getting to the bridge as they would check first with the binocular's. Also in a pitch black night like that with no moon or wave's binocualr's would make no differnece really, and the fact it was so cold impeeds your eye sight anyway.

I could go on and on, so Instead I will go find out the name of this documentary and tell you all when I find it .

Good day,

Martyn
