On September 3, 1925, the airship U.S.S. Shenandoah crashed, killing fourteen members of her crew. According to Wikipedia,
While passing through an area of thunderstorms and turbulence over Ohio early in the morning of September 3, during its 57th flight, the airship was caught in a violent updraft that carried it beyond the pressure limits of its helium gas bags. It was torn apart in the turbulence and crashed in several pieces near Caldwell, Ohio. Fourteen of Shenandoah's crew—including her commanding officer, Commander Zachary Lansdowne—were killed.
