An archival halftone documentary print recording the fuel calibration setup for the Spirit of St. Louis at Camp Kearny, San Diego. The aircraft rests on the unpaved field beside a stack of 55-gallon steel gasoline drums used by Ryan ground mechanics to pump measured fuel increments into the fuselage tanks. Donald Hall monitored each fueling stage to document takeoff distance versus gross weight across 70 to 300 gallons of gasoline.

The photograph clearly displays the massive black civil registration "N-X-211" painted across the upper surface of the right wing. Directly forward of the aft fuselage turtledeck, the rectangular cockpit skylight window is visible in the wing center section, engineered by Donald A. Hall to provide upward visibility and cockpit illumination.
