Snap parts together to build your airplane's body. Place engines to add thrust. Design and attach wings and then strap yourself into the cockpit and see how it flies. DOWNLOAD AIRPLANES Over 250,000 airplanes are available to download for free from SimplePlanes.com. Find anything from old WW2 bombers to next-generation fighters to sci-fi spacecraft. You can upload your own airplanes and rise through the ranks from a bronze builder to a gold level builder. DYNAMIC FLIGHT MODEL Flight simulation at its finest. Every little change you make in the designer impacts how the airplane flies. Weight distribution, thrust, lift, and drag are all calculated continuously while flying. Parts can break off in spectacular fashion while flying due to over-stress or by hitting something. The fun won't stop there though. You can keep on flying even with a missing wing if you've got the skills. SANDBOX MODE Use all available parts to build airplanes with no restrictions. The sky is the limit. Literally. CHALLENGES Climb into the cockpit of one of your custom aircraft and see how it does in the challenges. Land on aircraft carriers, dodge surface-to-air missiles, race through courses, and so much more. EDUCATIONAL Tutorials will help players learn the basics of real airplane design and the considerations that need to be taken when airplanes are made.
