"A Night to Remember" by Walter Lord
The "unsinkable" Titanic was four city blocks long, with a French "sidewalk cafe," private promenade decks, and the latest, most ingenious safety devices...but only twenty lifeboats for the 2,207 passengers and crew on board.
Gliding through a calm sea, disdainful of all obstacles, the Titanic brushed an iceberg. Two hours and forty minutes later, she upended and sank. Only 705 survivors were picked up from the half-filled boats of "the ship that God Himself couldn't sink."
