Airplanes stay in the air due to a phenomenon called lift. Lift is generated by the wings of the airplane as it moves through the air. The shape of the wings and the angle at which they meet the oncoming air causes the air pressure above the wing to be lower than the air pressure below the wing. This pressure difference creates an upward force, called lift, that keeps the airplane airborne. Additionally, the engines provide thrust to move the airplane forward, and the control surfaces like ailerons and rudder help the pilot steer and stabilize the aircraft.
