U.S. Navy Aviation Officers Inspecting Hall Low-Wing Monoplane X7621 (Circa 1928)

A primary historical photograph recording the military evaluation of Donald A. Hall Sr.'s proprietary low-wing monoplane X7621 at Dutch Flats in San Diego. Viewed from the rear three-quarter angle, the low-wing tandem monoplane rests on the dirt runway while Donald Hall stands at the rear cockpit conversing with two U.S. Navy officers in full uniform, including a naval aviator. Spectators and the hills of Point Loma across the bay frame this operational record of Hall presenting his design to military procurement officials.
