April 15, 1912: At around 12:45 a.m., the first lifeboat is lowered into the freezing water and the first distress rocket is fired. Lifeboats continue to be launched, mostly only half full. The last lifeboat is lowered into the Atlantic a little after 2 a.m.
More than 1,500 people are still on the TITANIC, now sitting at a steep tilt. At 2:18 a.m., the last radio message is sent and the TITANIC snaps in half. By 2:20 a.m., she has sunk beneath the icy waters of the Atlantic. 😢
