Have you ever been stranded in your car in the middle of a snowstorm? Now imagine there are 350 other people in the car with you, and you're all stuck in that storm in the middle of an Alaskan canal for nearly two days. People come to rescue you but can't get any closer. And with every passing hour, your car groans and threatens to sink. That was what happened to the SS Princess Sophia in 1918.
