If you go outside on a windy day, you realize just how strong air can be. It can lift a kite high in the sky and grab onto a balloon and carry it away. But even when the air is calm, you can feel its strength and resistance when you move. ""How Do Aircraft Fly?"" reveals the science behind air pressure and flying everything from hot-air balloons to helicopters to jet aircraft through eye-catching full-color photograph and illustrations, as well as through textual explanations of real-world examples.
