Washington State Aviation History

The first flight in Washington state took place in 1910 when Charles K. Hamilton flew in the Reims Racer aircraft over the air space of Seattle. Since then, aviation progressed rapidly in the state, with multiple enthusiasts and manufacturers starting the construction and implementing the engineering breakthroughs to planes. A year later, in 1911, the first aircraft landed at Pearson Field, considered the oldest among airports in Washington state. It was also the site of the first home-built airplane’s takeoff in 1912.

Another important landmark in WA aviation history has become the foundation of Pacific Aero Products Company by William Eduard Boeing in 1916 in Seattle. Renamed afterward as Boeing Airplane Company, the manufacture grew rapidly, Boeing aircraft being produced all over the state.

With the release of new aircraft, the need for airports grew as well. The end of the 1930s and the beginning of the 1940s were marked by the construction of airports that soon became the major ones in WA. Primarily serving as cargo transportation points and military bases, the airports continued development after WWII becoming the important hubs in the Northwest Pacific region.
