Zeppelin

Zeppelins were a form of airship invented by humans in the 20th century. They were mostly used as transport, but also had military uses.

The First Doctor and Susan Foreman mentioned having observed a Zeppelin air raid during World War I. (TV: Planet of Giants; AUDIO: The Alchemists) In a re-enactment of 1917 London, Lucie Miller and Yellow Beryl attempted to shelter from a Zeppelin bombing raid in the London Underground. (AUDIO: Dead London)

The Daleks used a Zeppelin to transport their ship Survey Ship Sigma to France during the First World War. When the Daleks were defeated, the Zeppelin lost air. (COMIC: The Dalek Project)

The Thirteenth Doctor obtained two zeppelins from the Blitz to use as balloons for Yasmin Khan's surprise birthday party. (PROSE: Dr. Thirteenth)

Pete's World
In Pete's World, private Zeppelins were owned by some of the richest people in society. Jackie Tyler wanted one for her birthday. A soldier told Mickey Smith that the people who used Zeppelins were "toffs". Cybus Industries produced their own Zeppelins. (TV: Rise of the Cybermen, The Age of Steel, et al.)

One account stated that the Preachers used an armed Zeppelin to free Paris from Cyberman control. The Zeppelin used its weaponry to destroy Cybermen on the streets whilst retrieving civilians and scientists. The Zeppelin finally transmitted the code which disabled the Cyberman emotional inhibitor and destroyed the Cyber-factory. (GAME: Save Paris) However, another account suggested Zeppelins weren't used in the liberation of Paris. (GAME: Cyber Assault)
