" After the Titanic hit the iceberg at 11:40 P.M., the ship’s radio operator sent out an SOS. An SOS is the international distress signal in Morse code. Unfortunately, the only ship near the Titanic had turned off its radio for the night. All the other ships who received the message were too far away to help. When the Titanic sank around 2:20 A.M., she was all alone. "
