Tucked along the north bank of the Columbia River lies Pearson Field, thought to be the nation's oldest continuously operating airfield. The golden age of aviation in the Pacific Northwest began at this spot with the touchdown of a dirigible bearing airmail letters, but that was only the first of many remarkable moments. From its conversion into a sawmill to provide spruce for World War I warplanes to hosting unexpected Russian airmen. Pearson Field adapted to serve the region through wars and peace alike. The Army Air Corps called it home for decades, and it attracted aviators like daredevil Silas Christofferson and Tex Rankin, who ran his own flight school. Author Martin Middlewood dives into the stories of the men and women who turned a grassy field into the historic site it is today.
