San Francisco Skyline Vista

This guide to the San Francisco Skyline Vista traces how a patch of bay water meant to become a municipal airport in the 1930s was instead built up from millions of cubic yards of sand and rock into an island for a world's fair. It follows the Golden Gate International Exposition of 1939, its four-hundred-foot Tower of the Sun and the Pan American Clippers that really did take off from here for Hawaii, before the Navy claimed the island for the war. Listen for what finally happened to the airport that was supposed to be here.
