Answer:
seems intuitive that sailboats, powered only by the wind, can travel easily with the wind at their backs, but it may seem impossible that they turn around and come home again, with the wind blowing straight against them.
But this reverse movement is possible because a moving boat's sail is shaped as an airfoil like the wing of a plane. When air moves over a plane's wing, from front to back, wind flowing over the top of the wing has to travel farther than wind flowing under the wing's bottom surface. This creates a pressure difference that lifts the plane.
