SimplePlanes is a game application that lets you build your own aircraft. You can design the airplane's wings, shape the fuselage, customize propeller engines, and more. Every change you make in the designer impacts how the airplane flies. Parts can break off in spectacular fashion while flying due to over-stress or by hitting something. You can keep on flying even with a missing wing if you've got the skills. The flight model updates in real time to accurately simulate any damage to your airplane's structure.
