Fata Morgana: A Possibly Titanic Mirage

A Fata Morgana is an optical phenomenon that can create strange shapes or a false wall of water above a watery horizon. This occurs when light reflecting off cold water is bent by an unusual layer of warm air above it, arriving at the observer from multiple angles. One hundred years ago, a Fata Morgana might have played a role in the sinking of the Titanic. This phenomenon can distort distant views significantly.
