Of course, we need to find airfields that you are able to land. Originally those small airplanes could land at any place, but the DC-3 is a bit larger and faster. The reason behind airport change in 1st and 2nd leg -there is not more on the route- is because in FS, Bellefonte have only 60 feet wide runway which is almost impossible to touch perfectly. Other runways along the route are suitable.
The flightplans I made are prepared for VFR/ direct GPS flying, but you can change it to any type you want. Because the pilots used visual navigation and a compass only, the preferred altitude for the legs do not go over 4000...6000 feet above the ground. With a nice scenery add-on, it will surely be an unforgettable tour.
We only need to take care of the planes...if you crash it, the tour is over !
