Donald A. Hall Estate Collection
Ryan NYP Split-Axle Landing Gear and Silvertown Airplane Cord Tires (May 1927)

An archival flightline negative capturing a low-angle three-quarter perspective of the Spirit of St. Louis at Dutch Flats. The composition details the heavy-duty split-axle landing gear engineered by Donald A. Hall Sr. to withstand the 5,200-pound maximum overload takeoff weight. The fabric-doped aerodynamic wheel disc is clearly stenciled "Silvertown Airplane Cord", documenting the pneumatic tires provided by B.F. Goodrich. The view also highlights the engine exhaust stacks, Clark Y wing profile, and tail registration in the background.
