In recent years, there have been frequent plane accidents, and the whereabouts of Malaysia Airlines, which was once a sensation, are still unknown. But despite this, the plane is still a relatively safe means of transportation. Because the probability of air crash is much lower than that of road traffic such as trains and cars, once it happens, it will be devastating, so the coverage intensity and exposure rate are relatively large, giving people the illusion that the plane is very unsafe. And there is a means of transportation that is safer than airplanes, that is, cruise ships. The possibility of a cruise ship crash is even lower than that of an airplane. Even if this minimal probability event occurs, the probability of escape at sea is very high.
