Hello, i am from slovakia and i am sorry for my grammar mistakes... I want ask this: i have many photos in titanic book and on one of those photos is titanic and above it olympic - two sister ships. It´s ok. But i don´t understand, why there, and no just there, but everywhere, is wrote, that between the titanic and olympic was just one bigger difference: that titanic has closed the "A" deck and olympic had opened the promenade deck "A", and that the titanic had unsteady separated the windows on deck "B".I read in book that dr. ballard found the titanic, but he couldn´t find the exact titanic epigraph wrote on the wreck, and that he found one "wall" inside the wreck, that was built just in olympic. So if i good understood, he think, that 14.april 1912 it was olympic which went under the water-this is wrote in my book. And now comes my most important question: Did somebody saw difference, that i found, between the two ships: Titanic has on photo just eight(8) windows on captain deck-or what is it-where is the direction wheel and engine controllers-control center(i don´t know the exact name of this part of ships-under the first ship funnel, but olympic is having on photo nine (9) windows-one more as titanic. DID SOMEBODY ANOTHER FIND ALREADY THIS DIFFERENCE BETWEEN THESE TWO SHIPS!?I think, that this is giant difference and i newer saw or heard in any book or document in tv, that somebody was talking about this differnece of two ships!!!
