I know others have mentioned this but some clever folks created a full length animation of Titanic sinking in real time. Meaning from start to finish it is 2 hours and 41 minutes. You get to see the ship collide, hear the orders given, and watch the evacuation and sinking. It is a pretty good rendering of Titanic but other experts will have to say if it passes muster or not. So if you have the desire to watch the whole thing, here it is.
23:40 (11:40 p.m.) Lookouts Fleet and Lee sight iceberg. Bell rung and call to bridge. Murdoch orders helm hard a-starboard and engines reversed. Starboard side scraped by iceberg for 300 feet puncturing hull in various places. Water fills forward compartments.
1200 (12:00 a.m.) Thomas Andrews tells Captain Smith ship is sinking estimating ship can stay afloat estimating no more than 2 hours. Lifeboats are lowered by hand, evacuation of passengers begins. Wireless is used to alert nearby ships. RMS Carpathia responds and begins moving towards Titanic.
02:20 (2:20 a.m.) Titanic sinks at 2:20 a.m.with over 1,500 lives lost.
0400 (4:00 a.m.) RMS Carpathia arrives and rescues approximately 710 from lifeboats. Captain Rostron of Carpathia said the area was an ice field with at least 20 large bergs measuring up to 200 feet in height and numerous smaller bergs.
18 April 1912 0930 (9:30 a.m.) RMS Carpathia docks at New York Pier 54. Prior to that it offloaded the only remaining piece of Titanic afloat, the lifeboats. Due to confusing communications, the initial reports were more promising about the the severity of the tragedy. The confusion was caused by mixed up bits of wireless communication resulting in erroneous reports of Titanic being towed to New York and less lives lost. By the time Carpathia arrived in New York, everyone knew that over 1,500 had died in the tragedy.
