The Model 8 design was inspired by the Ansaldo A.1 Balilla. The fuselage was covered in mahogany plywood, with a two-passenger forward cockpit and pilot rear cockpit, a seating configuration that would be the standard for all following three-seaters. The wing configuration and powerplant were similar to the Boeing Model 7.
The Model 8 first flew in 1920, and was the first aircraft to fly over Mount Rainier. The aircraft was destroyed in a hangar fire in Kent, Washington in 1923.
