Overflying Pan Am's new seaplane terminal on Treasure Island. All buildings of the Golden Gate International Exposition were razed down in 1940 to make room for a new land airport, but it became a naval facility instead. This is the second Boeing 314 airframe, the first to fly with triple tailfins. Named California Clipper, it was approaching Auckland in New Zealand on a regular transoceanic flight on 7 December 1941 when news came in of the Japanese attack against Pearl Harbor. Captain Robert Ford was ordered to proceed westward to New York and managed to complete an amazing 50,000 km trip via Australia, Java, Ceylon, Karachi, Bahrain, Sudan, Congo and Brazil.
