François-Xavier Mayer, known as "Fifou", never tires of flying over the fantastic landscapes of his native land, Madagascar. It sometimes takes several days to travel from one city to another by car.

At the helm of his small single-engine aircraft, Ian Lemaiyan, a Kenyan biologist and bush pilot, flies over the savannah to protect the rhinos.

Clark Butson founded an airline in the heart of Australia's arid desert. Its goal: to unite the isolated communities of the province of Pilbara, in the west of the country. Rescues, student transportation, supplies, visiting aboriginal communities.

Alessandro Huber works for a small transport company that flies over Suriname. In this country covered with 96% virgin forest.

Maheanuu Mourin is a pilot of the only Polynesian airline. On board its ATR, a turboprop aircraft capable of carrying up to 68 passengers, this 40-year-old Tahitian serves the most isolated islands of this region as big as Europe. He is the link between the communities. Without his plane, the daily life of the inhabitants of the atolls would be much more complicated.
