Features: "Little Kids Explore the World" is a series of books that amaze children. Realistic large photos showcase the world that children love to look at, think about, and explore; delicate illustrations reveal the mysteries of nature, society, and technology; and simple text is perfect for parent-child reading. Early biplanes used wooden frames, with one wing on each side of the fuselage, which could perform rolling maneuvers by twisting the wings. In 1912, a French pilot successfully flew a biplane across the English Channel. A trainer aircraft is specifically designed for training pilots, featuring two seats and two linked control systems. If the trainee makes a mistake in operation, the instructor can use the other system to correct it in time.
