USS Shenandoah (ZR-1) crash site

On 2 September 1925, Shenandoah departed Lakehurst on a promotional flight to the Midwest which would include flyovers of 40 cities and visits to state fairs. Testing of a new mooring mast at Dearborn, Michigan was included in the schedule. While passing through an area of thunderstorms and turbulence over Ohio early in the morning of 3 September, 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.
