Hall X-1 Prototype Profile on Field Stand at Camp Kearny (1928)

Donald A. Hall Sr. documented this clean, ground-level side profile of the experimental Hall X-1 (X7621) resting on the Camp Kearny dirt field. With the rear fuselage leveled on a heavy wooden sawhorse, a pilot sits in the forward cockpit while a mechanic attends to the empennage. The exposure highlights the low forward wing, the large cambered horizontal aft wing, and the engine-turned aluminum nose cowl, detailing the operational test configuration of Hall's patented aircraft.
