Eckener concluded that the puncture hypothesis, due to pilot error, was the most likely explanation for the disaster. He held Captains Pruss and Lehmann, and Charles Rosendahl responsible for what he viewed as a rushed landing procedure with the airship badly out of trim under poor weather conditions. Pruss had made the sharp turn under Lehmann's pressure; while Rosendahl called the airship in for landing, believing the conditions were suitable. Eckener noted that a smaller storm front followed the thunderstorm front, creating conditions suitable for static sparks.
