The history of human flight began in the 19th century with the development of lighter-than-air craft, laying the foundations for the modern aviation industry. While pioneering powered heavier-than-air flight came later in this timeline compared to our own, airships and balloons played a central role in the technological, economic and geopolitical revolutions of the early 20th century.
The first successful powered, controlled flights were achieved in the 1830s by European inventors and aeronauts experimenting with hot air balloons and early forms of airships. Key figures included Sir George Cayley in Great Britain, Henri Giffard in France, and Count Ferdinand von Zeppelin in the German Kingdoms.
Cayley is considered the first to build and fly a glider capable of carrying a human, in 1849. Giffard constructed the first engine-powered airship in 1852, demonstrating the potential for steerable, powered flight. However, it was the rigid airship (or "zeppelin") designs of Count Zeppelin in the 1890s that truly revolutionized lighter-than-air travel.
Zeppelin's rigid, aluminum-framed airships offered significant advantages over earlier balloon and airship designs in terms of size, speed, range and cargo capacity. By the early 1900s, commercial zeppelin services were operating between major cities in Europe, and the German Kingdoms had established a dominant position in both civilian and military airship technology.
Zeppelin airships were used extensively during the Great War for reconnaissance, bombing, and strategic transport, giving the German forces a major advantage. Their global reach also enabled greater German colonial expansion and economic influence. After the war, civilian airship travel flourished, with regular passenger and cargo routes connecting Europe, the Americas, Africa and Asia.
While airships were transforming early 20th century aviation, heavier-than-air flight with fixed-wing aircraft developed at a much slower pace in this timeline. The experiments of Orville and Wilbur Wright in the 1900s were viewed with skepticism by the public and military establishments, who prioritized the seemly more practical and proven zeppelin technology.
It was not until the 1920s that airplanes began to gain widespread adoption, initially for specialized military reconnaissance and cargo roles. Civilian air travel remained dominated by the luxurious and high-altitude zeppelin services well into the 1930s. It was only with the development of more powerful piston engines and the rise of long-range intercontinental routes that airplanes gradually displaced airships as the primary means of aviation.
The dominance of the zeppelin in early 20th century warfare dramatically shaped the course of World War I and World War II in this timeline. German airship fleets were able to conduct devastating strategic bombing campaigns, while also providing crucial transport, surveillance and supply capabilities. This helped the German and Austro-Hungarian empires maintain their positions as global superpowers for longer than in our own history.
Zeppelins also played a critical role in enabling greater colonial expansion and control, as well as the rise of new economic trading blocs centered around the German, British and French airship industries. This airship-based geopolitics persisted well into the mid-20th century, only receding with the development of jet-powered aircraft and space rockets.
While airships remained the mainstay of civilian and military aviation for decades, the eventual breakthroughs in jet engine and rocket technology in the 1950s transformed the industry once again. The first jet-powered airliners soon eclipsed the speed and range of even the largest zeppelins, while the rise of space exploration using powerful liquid-fueled rockets opened up a new frontier.
Today, while airships still have niche applications in areas like cargo transport and surveillance, heavier-than-air aircraft and spacecraft have become the dominant forms of aviation. However, the legacy of the pioneering European airship engineers and visionaries continues to shape the technological, economic and geopolitical landscape of this alternate timeline's world.
