Four-seat twin-boom metal aircraft designed by Thomas Shelton as the Shelton Flying Wing, although it was not what we call a flying wing today. First flown in Denver, Colorado in 1935 with fixed landing gear which was made retractable later that year. In 1936 the design was sold to the Timm Aircraft Company here at Glendale, but no production ensued. Photo by: John Underwood / Glendale Public Library
