Seagull Banking in Flight Against Coastal Clouds (1927)

The dark silhouette of a lone seagull banking gracefully in flight against textured coastal clouds. — Seagull Banking in Flight Against Coastal Clouds (1927) · Donald A. Hall Estate Collection

Studying natural fluid mechanics and airfoil efficiency, Donald A. Hall Sr. captured the clean silhouette of a solitary seagull banking through an overcast California sky in 1927. As an aeronautical engineer, Hall drew inspiration from avian flight dynamics, applying principles of natural lift and wing camber to his aircraft designs.
