Text version of updated How Do Planes Fly slide show. ... Airplanes are designed to let air pass around them with less drag. An airplane flies when all four forces work together. But, most airplanes need one more thing: They need a pilot to fly them! ... Airplanes need four forces to fly. Lift is one of them. Image Credit: NASA...

Four forces push and pull an airplane in flight. The wings act as an airfoil and produce an upward force called lift . The opposite of lift is the force of gravity , which pulls the aircraft downward. A force called drag , caused by air res...

Many believe that this explanation is incorrect because flat wings (such as seen on balsa wood airplanes, paper planes and others) also have managed to create lift. Please read How planes fly: the physical description of flight as well to get a fuller understanding of the creation of lift.

If this were all there were too it, then how could some planes fly upside-down? ... The planes propeller or jet engine, meanwhile, has to work to provide enough thrust to overcome drag. ... One more way to think about it: Ever "fly" your hand out car window? Try it sometime. If your hand (the airfoil) is level, it zips through...
