We have an excellent working relationship with MAF and other flight organizations, including fuel management.
Their pilot, Jeremiah, filled up fuel drums with fuel from the wing tanks of his aircraft so that I could refuel our helicopter on the flight home to our base. Shortly before Wamena, bad weather forced me to land. After two hours on the ground, the weather improved enough so that I could finish my flight back to the base safely, despite the stormy conditions.
The big advantage of a helicopter is that it can land in small spaces, i.e. pieces of land, where no aircraft can reach. This way it can rescue people from the jungle or take over the local distribution of food or other material.
