The Wright Military Flyer aboard a wagon in 1908
The Wright Military Flyer, designed and built by the Wright brothers, was one of the earliest military aircraft. In 1908, it was transported on a wagon as part of its testing and demonstration process for the U.S. Army. This method of transport reflects the era's technology and the Flyer’s compact and lightweight design, which allowed for easy movement. The Flyer’s development marked a significant milestone in aviation history, showcasing the potential of powered flight for military use.
The French reconnaissance balloon L'Intrépide (1796), the oldest surviving flying device, is preserved in the Heeresgeschichtliches Museum in Vienna.

In the late 18th century, the Montgolfier brothers invented the hot-air balloon, paving the way for manned flight. Around the same time, the discovery of hydrogen gas led to the creation of hydrogen balloons. Advances in mechanics, including fluid dynamics and Newton's laws of motion, contributed significantly to the development of modern aerodynamics, pioneered by Sir George Cayley. Balloons, both free-flying and tethered, began to see military use by the late 18th century, with France forming balloon units during the French Revolution.
In the 19th century, particularly its latter half, glider experiments by innovators such as Cayley, Otto Lilienthal, and Octave Chanute laid the groundwork for understanding winged flight dynamics. By the early 20th century, improvements in engine technology and aerodynamics enabled controlled, powered, manned flight. In 1903, the Wright brothers successfully combined these advancements to design and fly the first airplane. By 1909, the basic aircraft configuration with its cruciform tail was established, leading to rapid advancements in design, performance, and engine power.
The first large air vessels were rigid dirigible balloons, pioneered by Ferdinand von Zeppelin. These airships dominated long-distance travel until the 1930s when large flying boats became popular for trans-oceanic routes. After World War II, airplanes equipped with more advanced propeller engines and later jet engines replaced flying boats, revolutionizing both civilian and military aviation.
In the latter half of the 20th century, digital electronics brought significant advancements in flight instrumentation and "fly-by-wire" systems. The 21st century has seen the rise of pilotless drones for military, commercial, and recreational use, alongside the practical application of inherently unstable aircraft designs, such as flying wings, made possible by computerized controls.
