Airplanes have a lot of parts that are very complex. The science behind flying is simple. Airplane wings are shaped to make air move faster above the wing. This changes the air pressure around the wing and lifts the plane into the air. The pilot controls the plane from the cockpit. The cockpit has a control panel with lots of tools. The pilot talks to air traffic controllers on the ground for help. These controllers help keep air traffic safe and timely every day.
