101 years ago tomorrow, during WW1, Titanic's younger sister ship HMHS (His Majesty's Hospital Ship) Britannic struck a mine and went to the bottom of the Aegean Sea. Of the 1065 people on board, 30 died, most by being gruesomely blendered by the ship's propellers.

Here is an excellent real-time (just over an hour) CGI animation of the sinking, with commentary.
