'First Atlantic survey flight to Lisbon.' Another shot confirms the registration. NC16736 wore the name Pan American Clipper III just a month earlier. Photo probably taken off Alverca which handled seaplanes until 1938 when the Aeroporto Marítimo de Cabo Ruivo was established near the new landplane airport at Portela.

Later renamed Bermuda Clipper. The S-42 was used mainly on Pan Am's Miami - Rio route. Pending the completion of the Marine Air Terminal at New York - LGA, the modest Port Washington facility on Long Island was used for Atlantic flights, although revenue services only reached as far as Bermuda until the Boeing 314 became available just before WWII.
