How Do Wings Keep a Plane in the Air?

A passenger jet can weigh hundreds of tons. How can its wings keep it in the air? Follow the air around a wing, look inside its structure, and discover what changes from takeoff to landing. With flight footage, research imagery and animated diagrams, we explore lift, pressure, wingtip vortices, flaps, slats and the moving panels you can see from a window seat. We also unpack a familiar mistake: air travelling above and below a wing does not have to meet again at the trailing edge. Welcome to Cutaway — one piece at a time. Subscribe for more visual explorations of how things work. What should we open up next?
