It is created with Gamemaker by YoYo Games It isn't quite a realistic sim, but that was the closest, what you do is try to collect wind to keep the Wright Flyer airborn, also if you crash into houses, oh well. It is very cheap, but very fun.
This is a preveiw of Wright Flyer, you'll want to see it before you download it to see if you want it. This shows all the easter eggs, but how you find those, well you can figure that out!
