The story continues... In 1927, Latécoère began building his own brand of planes to replace the aging World War I aircraft Breguet 14. The Latécoère 25, (or "Laté 25") and, later, the Latécoère 26 and Latécoère 28 proved to be efficient aircraft when flying from Morocco to Senegal, and Mermoz himself flew the types on those routes on multiple occasions. But Africa was only the beginning. Latécoère's project was to create a direct airline between France and South America. By 1929, it had become evident that it would be economically viable for France to establish a commercial air route to South America, so Mermoz and others flew over the Andes. Despite Mermoz finding the flying conditions over the Andes to be tough, he became the project's main pilot, determined to reach the Pacific Ocean, and he was able, after multiple stops, to reach Santiago, Chile. During that time, to save time, he decided to fly during the night, using light beacons and flares as guides, and his fellow pilots, for once, were a bit reluctant to see him do it, because they knew it would be their turn next. For some time, as transatlantic flights were not yet possible, steamboats linked both halves of the "Line". After flying from Saint-Louis, in Senegal, to Natal, Brazil, in 12–13 May 1930, the line was complete at last. Unfortunately, the modified Laté 28 "Comte-de-la-Vaulx" did not prove reliable enough, and had to ditch at sea during the return flight. Mermoz, his two companions and the mail were rescued, but the plane sank during the attempt to tow it. In this picture you see the modified Latécoère 28 with floats for transatlantic flights from Senegal to Natal in Brazil.
