Zeppelin
LZ 72（海军名称 L 31）是属于德意志帝国海军的 R 级超级齐柏林飞艇。
它由经验丰富的指挥官海因里希·马蒂指挥，并在第一次世界大战期间参与了几次伦敦上空的突袭。
它还参与了 1916 年 8 月 19 日桑德兰突袭的侦察任务。它的最后一次飞行是在 1916 年 10 月 1 日深夜。
在伦敦以北几英里处，它被探照灯和防空火力击中。在这次交战中，正在巡逻的少尉伍尔斯坦·J·坦普斯特发现了这艘齐柏林飞艇。
他继续用燃烧弹攻击飞艇，导致飞艇起火并坠毁在波特酒吧附近的一片田野里。
全体机组人员遇难，最初乘员全部就地埋葬，但 1960 年代改葬于坎诺克蔡斯德国军人公墓。
此次灾难性坠机事故发生后，德意志帝国海军开始减少齐柏林飞艇的袭击次数。
==========================================
LZ 72 (navy designation L 31) was an R Class super-zeppelin belonging to the Imperial German Navy.
It was commanded by Kapitänleutnant Heinrich Mathy, an experienced commander, and took part in several raids over London during World War I.
It also participated in a reconnaissance role during the Sunderland raid of 19 August 1916.
Its last flight was launched late at night on 1 October 1916. Several miles north of London, it was caught in searchlights and anti-aircraft fire.
During this engagement, 2nd Lt. Wulstan J. Tempest was on patrol and spotted the zeppelin.
He proceeded to engage the airship with incendiary rounds, causing the ship to burst into flames and crash in a field near Potter’s Bar.
The entire crew died, and were originally buried there but were reinterred at Cannock Chase German Military Cemetery in the 1960s.
After this disastrous crash, the Imperial German Navy began reducing the number of zeppelin raids.
