How Do Airplanes Stay in the Air? The Science of Flight Explained

How does a heavy airplane stay in the air? Join Professor X for an illustrated journey from the runway to cruising altitude—and safely back to the ground. In this 24-minute explainer, we'll follow one flight to see how wings, moving air, jet engines, and flight controls work together. Discover the four forces of flight, what a wing does to the air, why speed and angle matter, and how pilots manage takeoff, turns, turbulence, and landing. We'll also explore why wings flex, how an airplane can glide without engine power, and why an aerodynamic stall is about airflow—not simply an engine stopping.
