Airplanes stay aloft because wings generate lift as they move through air. Their shape and angle help create a pressure difference and redirect airflow downward, while engines provide the forward thrust needed to keep air moving over the wings.
Flying is really a balance of four forces: lift, weight, thrust, and drag. Once that balance is understood, aviation feels less like magic and more like an elegant application of physics and engineering.
