On 14 April 1912, 100 years ago today and four days into the crossing and about 375 miles (600 km) south of Newfoundland, Titanic hit an iceberg at 11:40 pm (ship's time; GMT−3). The glancing collision caused Titanic's hull plates to buckle inwards in a number of locations on her starboard side and opened five of her sixteen watertight compartments to the sea. Over the next two and a half hours, the ship gradually filled with water and sank. Passengers and some crew members were evacuated in lifeboats, many of which were launched only partly filled. A disproportionate number of men – over 90% of those in Second Class – were left aboard due to a "women and children first" protocol followed by the officers loading the lifeboats. Just before 2:20 am Titanic broke up and sank bow-first with over a thousand people still on board. Those in the water died within minutes from hypothermia caused by immersion in the freezing ocean. The 710 survivors were taken aboard from the lifeboats by the RMS Carpathia a few hours later.
