Build airplanes by snapping parts together, designing wing sections, and attaching engines. At any time, you can strap yourself into the cockpit and see how it flies with realistic physics. If you're not in the mood for building, over 250,000 airplanes are available to download for free. BUILD AIRPLANES You have the tools you'll need to bring any airplane to life. 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.

This 3D game has been developed in the context of an international, aviation safety research project (http://hcilab.uniud.it/aviation), aimed at exploring possible new approaches to safety education, and featured on important media such as TIME, Popular Mechanics, Discovery Channel, and Fox News (see http://hcilab.uniud.it/aviation/media.html). Prepare for Impact is the world-first game that reproduces the experience of real aircraft emergencies from the passenger’s viewpoint, with the highest fidelity allowed by today’s mobile devices. In each virtual emergency experience, the player can try first-hand right and wrong actions that a passenger can take, and see the positive or negative consequences those actions have. Your goal is to take all the right decisions to come out from the plane unharmed as fast as possible. The different levels of "Prepare for Impact" depict major types of emergencies, such as in-flight decompression, ground collision, runway overrun, water landing, crash landing, rejected take-off, and fumes in the cabin. Moreover, they are able to simulate the different threats that can make aircraft evacuation more complex, such as fire, smoke in the cabin, water, unusable exits, and others. The latest version of the app also includes a level editor that allows players to create personalized evacuation scenarios. The game also offers the option of publishing your best evacuation results on world leaderboards.
