The Wright brothers, Orville Wright (August 19, 1871 - January 30, 1948) and Wilbur Wright (April 16, 1867 - May 30, 1912), are generally credited with making the first controlled, powered, heavier-than-air flight on December 17, 1903. In the two years afterward, they developed their flying machine into the world's first practical airplane, along with many other aviation milestones.

In 1878 Wilbur and Orville were given a toy "helicopter" by their father. The device was made of paper, bamboo and cork with a rubber band to twirl its twin blades, and about a foot long. The boys played with it until it broke, then built their own. In later years, they pointed to their experience with the toy as the initial spark of their interest in flying.
