April 15 2012 marks 100 years since the British ship RMS Titanic sank at 2:20 AM on April 15th 1912, having collided with an iceberg 2hrs and 40 minutes earlier.
Calls for help were heard by many ships but the closest ship, the Carpathia, was 4 hours away from the sinking Titanic. Titanic sank 2 hours before the Carpathia arrived to rescue survivors. Some survivors died of hypothermia shortly after they were recovered.
The Titanic's first and only passenger voyage had lasted less than five days.
