We can't imagine our lives without transportation anymore. We enjoy bike rides, take buses or cars to school, travel on trains and planes... Fire trucks and ambulances, SUVs, construction equipment... Transportation shortens distances, makes our work easier, and helps save lives. That's why it's especially interesting to understand how it works. We'll tell you and show you what's inside. You'll learn why airplanes fly and ships float. See where rockets take off from and how submarines dive. You'll learn about the transportation of the past and even the future. Colorful, detailed pictures featuring every detail await you.
