Donald A. Hall Estate Collection
In-Flight Aerial View of Wing Strut and San Diego Bay from Ryan NYP Cockpit (May 1927)

An archival aerial photograph captured by Donald A. Hall Sr. through the right cockpit window of the Spirit of St. Louis during airborne flight trials. Looking downward along the streamlined forward wing lift strut and landing gear jury brace, the image captures the coastal waters, tidal flats, and coastline of San Diego Bay and Point Loma below. This photograph documented the aerodynamic stability and deflection of external wing bracing under dynamic cruising loads.
