An elevated aerial overview of Dutch Flats airfield in San Diego from the historical archives of the San Diego Air & Space Museum. The photograph captures the wooden Ryan Flying Company hangar painted with "RYAN FLYING CO.", "SCHOOL OF AVIATION", and "LOS ANGELES-SAN DIEGO AIR LINE" signage, flanked by an aviation booking office and parked Ryan biplanes on the dirt flight line. Across the unpaved field, the expansive tidal mudflats of San Diego Bay are visible, providing environmental documentation of the airfield where the Spirit of St. Louis was designed, constructed, and initially test-flown.
