This wonderful LEGO Diorama by 74louloute is apparently inspired by real life events:
Guillaumet carried the mail between Argentina and Chile. On Friday 13 June 1930, while crossing the Andes for the 92nd time, he crashed his Potez 25 at Laguna del Diamante in Mendoza, Argentina, because of bad weather. He walked for a week over three mountain passes. Though tempted to give up, he persisted while thinking of his wife, Noëlle, until June 19 at dawn when he was rescued by a 14-year-old boy named Juan García. He reached a village whose inhabitants could not believe his story. This exploit made him stand out among the ‘stars’ of Aéropostale.
