The voyage of the China Clipper, a Pan American Airways flying boat, across the Pacific Ocean in 1935 is recounted. Using dramatic reenactments, interviews with historians and biographers, archival photographs, newsreel clips, and film, the documentary series recounts the creation of this technological innovation, which was led by Pan Am's chief executive Juan Trippe, pilot Charles Lindbergh, airplane engineer Igor Sikorsky, and radio engineer Hugo Leuteritz.
