Zeppelin LZ 25

Zeppelin LZ 25, with the military designation Z IX, was the 25th airship constructed by Count Ferdinand von Zeppelin and the twelfth Zeppelin commissioned into German military service. It made its first flight on 13 July 1914 and was delivered to the Army. After the outbreak of the First World War it was moved to Düsseldorf for front-line use and often operated alongside the militarized passenger airship Sachsen from Cologne, flying reconnaissance missions and bombing raids over Antwerp, Calais, Ostend and Dunkirk. On 8 October 1914 a Royal Naval Air Service aircraft dropped two bombs into its hangar at Düsseldorf, which ignited the hydrogen and destroyed the airship completely, although its externally mounted engines survived.
