How Airplanes Fly. Airplanes fly because they are able to generate a force called Lift which normally moves the airplane upward. Lift is generated by the forward motion of the airplane through the air. This motion is produced by the Thrust of the engine(s).The figure below is a simple diagram of the four forces acting on an airplane Thrust, Lift, Drag and Weight.Drag is the force produced by the resistance of the air to the forward motion of the airplane. Swish your hand rapidly side-to-side and you will feel that resistance on your hand.his motion is produced by the Thrust of the engine(s). The figure below is a simple diagram of the four forces acting on an airplane Thrust, Lift, Drag and Weight. Drag is the force produced by the resistance of the air to the forward motion of the airplane.
