Book excerpt: In 1928, Charles Kingsford Smith and Charles Ulm made the first trans-Pacific flight in the Southern Cross - an aircraft constructed largely of wood and fabric. They made the trip from Oakland, California, in nine days, during which they faced electrical storms, torrential rain, equipment failure, and fuel shortages. Navigational aids were primitive - contact with the outside world was by Morse code only - and safety measures were non-existent. After many close calls, they triumphantly landed in Brisbane, where a crowd of 15,000 welcomed them as heroes. Throughout this extraordinary journey, Ulm kept a logbook in which he recorded his raw impressions of the flight. Using Ulm's logbook, plus contemporary newspaper accounts and official documents, Flying the Southern Cross tells the gripping tale of this history-making flight, and the aviators who made it happen.
