Caption: Aeroplane wing model, coloured wind tunnel image. This low-speed airfoil (wing) model is being studied in a smoke-flow-visualization wind tunnel. When at a large angle-of-attack to the oncoming flow, as shown here, such an airfoil 'stalls', with separated flow and turbulence on its upper surface. If this happens to a real aircraft, the loss of lift causes a dramatic drop in altitude.
