I was thinking, it's easier to construct a balloon, or a glider, than it is to construct an air plane.
So what if you constructed a balloon glider?
It uses a balloon system to get to the higher altitudes, then it lets out it's wings, and closes it's balloon system, and lets out it's wings.
Then you get the manueverability/speed of a glider, with the capacity for vertical takeoff of a balloon.
Also, it would be cheaper to construct than an airplane.
It might be useful in the future without many other means of air travel, while simultaneously avoiding contact with the restless angry natives.
