The familiar story of the RMS Titanic--from her tragic 10-second encounter with an iceberg to her descent to the bottom of the ocean some three hours later, taking with her more than 1,500 lives--still looms large in the popular imagination. Daniel Butler, a researcher and archivist, worked on this book for 30 years, intensively compiling facts not only about the event, but also about the characters who played an important role, from the actions of Captain Smith and his crew to the inescapable fate of the third-class passengers. He also offers the startling revelation of a nearby ship which ignored the Titanic's distress call because the shipmates were afraid to awaken their captain. Unsinkable explores every facet of the Titanic's history, from its conception to a modern-day researcher's attempts to salvage the ship. The author presents a contemporary view of the crew and the passengers aboard, creating a better understanding of the time and the social psyche that played a role in the disaster. Also of note is Butler's enlistment of a clinical psychologist to analyze Captain Smith's mental state as the drama unfolded before him. Butler's passionate yet balanced narrative permits readers to conclude for themselves who or what was ultimately responsible for sinking the unsinkable ship.
