At the end of the 1920s, crossing the Atlantic was a challenge, that only a few daredevils managed to accomplish. Among them were the pioneers of the Aéropostale, the well-known mail-carrying airline of the early days of aviation. Henri Guillaumet was a regular on the South American crossings. Until his 92nd, which proved to be one too many. Poor Henri, would have to be very resistant, indeed, to cross the snowy Andes Cordillera on foot... it was a matter of life or death.
