Summer is typically a time for travel. Many people travel by air to get to their destination faster. Have you ever wondered what makes that airplane fly? This interactive site will help visitors understand more about the forces of flight. Understand how the engine has to deliver enough thrust to surmount the drag force. Also recognize why engineers try to make airplanes light and shape the blades to add lift. Once you think you have the aerodynamic principles down, you can try your hand at designing an airplane.
