The Yankee Clipper
At the request of Pan American airlines, Boeing won the bid successfully in 1936 to build the Boeing 314 - with unprecedented range, passenger accommodations and "one class" service.
The first 314 flight on the San Francisco-Hong Kong route left Alameda on February 23, 1939 with regular passenger and Foreign Air Mail Route #14 service beginning on March 29.A one-way trip on this route took over six days to complete. Commercial passenger service lasted less than three years, ending when the United States entered World War II in December 1941.
The standard of luxury on Pan American's Boeing 314s has rarely been matched on heavier-than-air transport since then and represents the quintessential "Romance of Flight".
