Long before aerospace emerged as a major American industry, the desire to rise above the ground had already become tied to exploration, military advantage, mobility, and national progress. During the Civil War, observation balloons carried military personnel into the air for reconnaissance, introducing an entirely new perspective on warfare and distance even while aviation itself remained primitive and unpredictable.

In the decades that followed, experimenters across the United States and Europe pushed flight further into the realm of engineering and controlled movement. John J. Montgomery conducted glider experiments in California during the late nineteenth century and is believed to have achieved one of the first controlled glider flights in the United States. Around the same period, the Wright Brothers continued experimenting with lift, balance, propulsion, and control through repeated testing and mechanical refinement. They were not alone. Early aviation attracted engineers, mechanics, inventors, and tinkerers working through trial and error while much of flight still appeared impractical, dangerous, or temporary.

After powered flight emerged in the early twentieth century, aviation quickly became a source of enormous public fascination. Crowds gathered at fairs, exhibitions, and early air meets to watch pilots test fragile machines constructed from wood, fabric, and wire, often powered by unreliable engines and limited instrumentation. Many of the aircraft appeared only briefly above the ground before mechanical failure or crashes interrupted the demonstrations. The 1910 Los Angeles International Air Meet at Dominguez Field introduced powered aviation to massive public audiences and helped transform flight into both an aviation spectacle and a symbol of modern progress. Similar exhibitions and air meets soon appeared across the country as public fascination with aviation continued to grow.

As designers and pilots gained experience, aviation gradually evolved beyond exhibition and toward transportation, military use, and commercial expansion. Pioneers including Glenn Curtiss helped move American aviation toward larger aircraft companies, organized flight instruction, and increasingly sophisticated engineering during the early twentieth century.

Although aviation remained relatively young, wartime demand during World War I accelerated its growth at a pace that would have been difficult during peacetime alone. Aircraft proved valuable for reconnaissance, combat, and transportation while exposing the need for more reliable engines, standardized construction methods, trained personnel, and coordinated support networks. Factories expanded rapidly as governments and private industry rushed to increase aircraft output. Aviation was no longer operating primarily through isolated experimenters and public exhibitions. It was becoming a national industrial enterprise.

Although arge scale bombing would not occur until the Second World War, the airplane contributed to the mass destruction that the Great War brought.
