During the early morning darkness of 3 September 1925, USS Shenandoah (ZR 1), U.S. Navy rigid airship, was flying over southeastern Ohio when she abruptly encountered violent atmospheric conditions. Her hull structure was overstressed amidships, breaking the airship in two. Shenandoah's external control car and two engine cars fell free, carrying the dirigible's Commanding Officer, Lieutenant Commander Zachary Lansdowne, and several other men to their deaths. The stern section came down nearby, while Lieutenant Commander Charles E. Rosendahl and several men were able to fly the bow section to ground as a free balloon. In all, twenty-nine of those on board survived.
