Zeppelin LZ 56

Zeppelin LZ 56, operationally referred to as LZ 86, was a German rigid airship built by Luftschiffbau Zeppelin at its Löwenthal works at Friedrichshafen and operated by the German Army in the First World War. It was a P-class airship that was converted to the Q-class in April 1916 by lengthening the hull to increase gas volume and replacing the engines. It served on the eastern and south-eastern fronts and made seven bombing missions, dropping about 14,800 kilograms of bombs on targets in Latvia, Belarus and Romania. On the night of 3 to 4 September 1916 it took part in operations against Bucharest and Ploiesti, was caught by searchlights and heavy anti-aircraft fire, and lost lift; the crew vented the hydrogen cells to descend, and the main body crashed near the village of Utvin, about 80 kilometres from its base.
