In 1903, the Wright brothers created the first powered and controlled aircraft in history. In more than a century, the technological development of aviation has been phenomenal. Of course, the two world wars greatly increased the progress of aviation. In 1910, the first jet plane appeared on the scene. It took another 42 years to see the first airliner. One of the latest and most important developments in this field took place in 2004 with the Solar Impulse, the first solar-electric plane to fly around the world.
