A flightline documentary photograph showing the Spirit of St. Louis rolling out across the unpaved dirt surface of Dutch Flats following a test flight. Positioned in the distance against the San Diego hills, the aircraft demonstrates the landing roll and tail-skid braking characteristics evaluated by Donald Hall to determine short-field landing performance on unpaved fields.
