Pearson Field, part of the Vancouver National Historic Reserve, is one of the oldest continually operating airfields in the United States. From the first arrival of an airship in 1905 and the flying of a plane off the Multnomah Hotel in 1912, Pearson has achieved numerous aviation milestones. The first official interstate airmail landed here in 1912, and during World War I it was the site of the world's largest spruce mill. Pearson was selected to serve as Portland's first airmail terminal, and two of America's most notable women pilots--Dorothy Hester and Edith Foltz--first took to the skies from the bustling Vancouver field. Pearson was also in the world spotlight when the 1937 Soviet transpolar flight landed in 1937. After 100 years, Pearson continues to serve as one of the region's preeminent general aviation centers.
