The main types of airship are non-rigid, semi-rigid, and rigid. Non-rigid airships, often called "blimps", rely on internal pressure to maintain the shape of the airship. Semi-rigid airships maintain the envelope shape by internal pressure but have a supporting structure. Rigid airships have an outer structural framework which maintains the shape and carries all structural loads, while the lifting gas is contained in internal gas bags or cells. Rigid airships were first flown by Count Zeppelin and the vast majority of rigid airships built were manufactured by the firm he founded. As a result, all rigid airships are sometimes called zeppelins. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Airships were most commonly used before the 1940s, but their use decreased over time as their capabilities were surpassed by those of aeroplanes.

Heavier than Air: From first heavier-than-air manned flights, to a dawn of modern aviation.

Following the outbreak of war in 1914, the conflict rapidly grew towards ‘Total War‘. During the early years of the war, poster design and distribution in Britain was organized by the War Propaganda Bureau run out of Wellington House in London. Many of the designs and content of the posters produced during this period were decided internally without oversight from the British Parliament. From 1916 onward, the production of posters and propaganda was centralized through the British Government and, by 1918, were run primarily by the British Ministry for Information. All posters in this collection are printable in high definition.
