Swan Island Airport, 1939

Portland’s rudimentary Swan Island Airport is clearly illustrated in this 1939 top-down photo. It was common in those days of unsophisticated instruments to paint the city name on a roof so early pilots knew they had the right (or wrong) airport. Except for rail lines, Mocks Bottom appears to be completely undeveloped at this time.
