In my opinion, it wasn't exactly anyone's fault in particular that the Britannic sank; it was actually vastly improved after its older sister went down - it was still in the shipyard being built then, so there was still space to make said improvements - including things like reusable lifeboat davits that could lower multiple boats at once, watertight compartments with much higher limits (not to mention raising the number of sections that could be flooded without sinking)...in the end, one of the largest contributing factors to its sinking was that as it was being used as a hospital ship, the on-board medical staff had opened all the windows for some fresh air some time previously, so when the portholes nearest the surface were submerged a few minutes after the ship hit a mine, Britannic was just barely pushed over the water limit (which was six compartments, as opposed to Titanic's 2-4). If I recall, most of the people who had died in the sinking were those who launched lifeboats too near to the still-spinning propellers, which had just emerged from the water around that time.
Considering that Britannic sank three times as quickly as Titanic (within ten minutes of hitting the mine, the former was in the same condition as the latter was an hour after the iceberg), I'd say her captain did a pretty good job of trying to save the ship and those on board.
Oh, you bet I've heard of her. And a great deal of the other ships operated by the White Star Line. It's quite saddening to think of the fate of all of those ships. Have you heard about the restoration of the SS Nomadic? The last remaining White Star ship?
This is incredible. This is absolutely incredible. It looks SO beautiful and so real.. Every little piece of it. And you've mastered it in cartoon style! Good good job Icaron. Standing ovation for you!!!
