Introduction
Before the flying saucer became the dominant image of UFO culture, pulp science-fiction magazines had already taught readers to recognise many different kinds of flying machines. From the 1920s through the early 1940s, magazine covers and stories presented spacecraft as rockets, cylinders, spheres, streamlined liners, flying submarines and elaborate hybrid vehicles. The result was a subtle but important shift in expectations: a technological craft did not have to resemble a conventional aeroplane to be interpreted as a machine. When later witnesses reported unusual aerial objects, they were describing them within a culture already familiar with the idea that advanced vehicles might take unfamiliar forms. This did not create UFO reports, but it broadened the range of shapes that could plausibly be read as engineered craft rather than natural phenomena.

Rockets, cylinders, liners and hybrid machines
Early science fiction inherited a wide assortment of spacecraft concepts rather than a single visual template. Nineteenth- and early twentieth-century stories imagined space travel in projectiles fired from giant guns, spherical vessels, bullet-shaped craft and even machines resembling submarines. Because propulsion methods were often fictional or unexplained, designers were not constrained by the aerodynamic requirements that shaped real aircraft.

When specialised science-fiction magazines emerged in the pulp era, this diversity became even more visible. According to The Encyclopedia of Science Fiction, illustrators such as Frank R. Paul frequently depicted spacecraft as enormous bloated aeroplanes, rounded ocean liners with rows of portholes, or fantastical vehicles combining features from ships, cars and aircraft. Many covers showed machines whose purpose was immediately recognisable as transportation, yet whose shape differed dramatically from any aircraft then flying in the real world.

Several recurring forms appeared across pulp illustrations:
- Rocketships with fins, flames and pointed noses.
- Cylindrical vessels resembling giant shells, tubes or projectiles.
- Space liners inspired by ocean-going passenger ships, complete with windows and decks.
- Flying-submarine hybrids, borrowing imagery from underwater exploration.
- Spherical and bulbous craft, often justified by fictional propulsion systems. [SF Encyclopedia]sf-encyclopedia.comSF Encyclopedia SFE: SpaceshipsSF EncyclopediaSFE: SpaceshipsFebruary 17, 2025
The important cultural effect was that readers learned to identify a vehicle through context and function rather than through a fixed shape. A machine could be round, elongated or completely unconventional and still be understood as a craft.
Why saucers were not the only imagined shape
Modern discussions sometimes assume that science fiction primed the public specifically for saucer-shaped UFOs. The historical record is more complicated. Pulp magazines displayed an extraordinary range of spacecraft designs, and saucers were only one possibility among many.
Frank R. Paul, arguably the most influential artist of early American science fiction, became famous for illustrating giant machines of every conceivable form. Commentators on his work have noted that he even depicted saucer-like spacecraft before the term “flying saucer” entered popular culture, but those images existed alongside rockets, globes, towers, cylinders and elaborate mechanical structures. The defining feature was not the saucer shape itself but the assumption that advanced technology might look radically different from contemporary engineering.

This distinction matters. If pulp readers had been exposed only to aircraft-like spacecraft, then later reports of discs, cylinders or unconventional objects might have seemed less technological. Instead, decades of illustration had already normalised the idea that future vehicles could abandon familiar aviation forms. The visual culture of the pulps expanded the category of what counted as a machine.
How visual variety prepared UFO interpretation
The mechanism linking pulp magazines to later UFO interpretation was not prediction but expectation management. Real aeroplanes trained observers to associate technology with wings, propellers and recognisable aerodynamic structures. Pulp science fiction weakened that expectation by repeatedly presenting vehicles that achieved flight or space travel through entirely different principles.

Readers therefore encountered three related ideas:
- Advanced technology might not resemble current technology.
- A vehicle could be engineered even if its purpose or propulsion was unknown.
- Unusual shapes could signal greater sophistication rather than impossibility. SF Encyclopedia
This mental framework became especially important in a period when aviation itself was changing rapidly. Between the First World War and the dawn of the jet age, aircraft design evolved dramatically. Against that backdrop, pulp illustrations encouraged readers to think that future machines might depart even further from present-day norms. A strange object in the sky could therefore be interpreted not merely as an anomaly but as a vehicle operating according to principles beyond contemporary engineering. Encyclopedia Britannica
The effect was cultural rather than evidential. Pulp magazines did not tell readers what UFOs were. They helped create a visual vocabulary in which a technological craft no longer needed to look like an aeroplane.
The lasting shift in technological imagination
By the time the UFO era emerged after 1947, popular culture had already spent two decades absorbing images of spacecraft in wildly different forms. Adventure magazines such as Amazing Stories, Wonder Stories and Astounding circulated covers filled with machines that ignored ordinary aviation conventions while remaining clearly artificial and purposeful. Encyclopedia Britannica+2SF Encyclopedia
That legacy helps explain why reports of discs, cylinders, cigar-shaped objects and other unconventional aerial forms could be interpreted as craft rather than immediately dismissed as impossible. The pulps had already loosened the connection between “machine” and “aeroplane”. In the imagination shaped by early science fiction, technology occupied a much broader visual territory. A flying object could be strange, unfamiliar and unlike any aircraft on Earth, yet still look as though it belonged to a civilisation capable of building vehicles. SF Encyclopedia
