SimplePlanes is a game where you would be building airplanes by putting parts together, attaching engines, and designing wing sections. Once the airplane is made, you may step inside the cockpit and check the plane’s flying capabilities. If you don’t feel like building the plane and want to directly jump to the flying part, you may choose a plane from the more than 250,000 planes available for free download. You would find a variety of planes there – from old World War II bombers to sci-fi spacecrafts to modern fighters.
