Yes Yes Yes!! I've been fascinated by Titanic since the news reports of Ballard's discovery in '85. It was right before my 8th birthday.
Last month, I watched this great Smithsonian documentary called Titanic's Final Mystery, about a new theory surrounding the ship's sinking. The official reports blamed the crow's nest crewmen for not having spotted the iceberg sooner, suggesting that they were either asleep, or one of them had abandoned his post temporarily. In fact, neither of them were asleep. One of the men DID leave the crow's nest to get them some hot cocoa, but that was several hours before Titanic struck the iceberg. The temperature had plunged sharply in a very short amount of time and neither of them were prepared for that.
The documentary suggests that this drop in temperature was partially to blame for the sinking. Under such conditions, a phenomenon called a Fata Morgana occurs, which is the fancy name for a mirage (Wikipedia entry with accompanying pictures of oceanic mirages). On land, you can see this effect in extreme heat, when it looks like there's water on the ground due to reflections of what's above the horizon. At sea, this happens under cold conditions and the mirage is flipped - the ocean is reflected into the sky. Several German ships passed through Titanic's route a few hours before her fatal strike, and their logs noted the fuzzy horizon. However, it was worse when Titanic went through because the cold conditions, along with the icebergs, had drifted into that route in the meantime.
This fuzzy horizon meant that the men in the crow's next wouldn't have even seen the iceberg until it was too late. It literally appeared out of nowhere, just as a land mirage disappears when you approach it. On top of that, the moonless, star-filled sky made it even harder to spot dangers.
Also to blame was Captain Smith's order to go full speed despite the conditions. It gave the ship no time to correct course once the iceberg was spotted.
Another fatal mistake was that the telegrapher in charge that night ignored the iceberg warnings. Titanic had just exited the Atlantic's communication dead zone and there was a backlog of (first class) messages that needed to be transmitted to land. He focused on that job instead of the warnings. The second telegrapher wasn't on duty at the time, but was in the telegraph room. He survived the wreck, which is why we have his testimony.
The mirage proved fatal once again after the crew realized that Titanic was, in fact, going to sink. Several people noticed what appeared to be a ship on the horizon, which was the California. However, because of the fuzzy horizon, the California's captain didn't believe he was looking at the Titanic because it appeared far too small. It caused him to mistake the world's largest ship for a schooner. The signalman aboard the California DID see Titanic's SOS signal, but couldn't discern the pattern because of the mirage. To him, it might have been a twinkling star. California's signalman endeavored to respond anyway, but Titanic's signalman couldn't read California's reply, also due to the mirage. It looked to him like the California wasn't responding. That explains why the California didn't come to Titanic's aid.
For the curious Titanic buffs, that documentary is on Netflix. It's totally worth watching.
