Mickey, Minnie, Donald, Daisy, Goofy and Pluto are ready to take you on an adventure ride through the world of learning. Discover the secrets of science, nature, our world, the past and much more. Climb aboard and enjoy the ride. Just 100 years ago, the fastest way to travel over land was on horseback. Then cars and trains took over and became even more speedy, safe and comfortable. At about the same time, steam engines replaced wind filled sails as the power source for boats and ships. But our biggest travel adventure has been in the air. First there were balloons, blown along by the wind. Then bumpy biplanes led to today's sleek, high flying jets, which include a plane that travels twice as fast as a bullet.
