Primary injuries are caused by blast overpressure waves, or shock waves. Total body disruption is the most severe and invariably fatal primary injury. [2] Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. [3]
During the Attack of Pearl Harbor, the USS Arizona was struck with an armor-piercing bomb which penetrated the upper deck and stopped inside the forward magazine.

Similar to the 1957 incident, safety precautions meant that the plutonium was not mounted to the bomb but rather stored elsewhere on the plane at the time.
