Are airships allowed? They are now.

This is a Zeppelin, a symbol of pride to Germans and one of terror to the British during WWI. And before you call me a N*zi, Zeppelins were only used in WWI. Y’know, before the N*zi Party was formed.
Zeppelins were primarily used for attacks on civilian cities in Britain, which lead to their becoming feared by British civilians. By the end of the war, Zeppelin air raids had killed around 557 people and wounded 1,358 more (Dusch, “Zeppelin”, International Encyclopedia of the First World War).
I understand that a machine’s body count is not necessarily something to admire. However I am a sucker for aviation and the history of it, especially from the period of WWI. So to ride the coattails of @FafasMcMelt and share my favorite literal ship rather than the idea of two characters being in a relationship, I figured a respected and feared airship from the First World War would be the best choice for me to go with.
